Chapter 2
Job-Order Costing: Calculating Unit Product
Costs
Questions
2-1 Job-order costing is used in situations
where many different products, each with individ-
ual and unique features, are produced each pe-
riod.
2-2 In absorption costing, all manufacturing
costs, both fixed and variable, are assigned to
units of product—units are said to fully absorb
manufacturing costs. Conversely, all nonmanufac-
turing costs are treated as period costs and they
are not assigned to units of product.
2-3 Normal costing systems apply overhead
costs to jobs by multiplying a predetermined
overhead rate by the actual amount of the alloca-
tion incurred by the job.
2-4 Unit product cost is computed by taking
the total manufacturing costs assigned to a job
and dividing it by the number of units contained
in the job.
2-5 The first step is to estimate the total
amount of the allocation base (the denominator)
that will be required for next period’s estimated
level of production. The second step is to esti-
mate the total fixed manufacturing overhead cost
for the coming period and the variable manufac-
turing overhead cost per unit of the allocation
base. The third step is to use the cost formula Y
= a + bX to estimate the total manufacturing
overhead cost (the numerator) for the coming pe-
riod. The fourth step is to compute the predeter-
mined overhead rate.
2-6 The job cost sheet is used to record all
costs that are assigned to a particular job. These
costs include direct materials costs traced to the
job, direct labor costs traced to the job, and man-
ufacturing overhead costs applied to the job.

When a job is completed, the job cost sheet is
used to compute the unit product cost.
2-7 Some production costs such as a factory
manager’s salary cannot be traced to a particular
product or job, but rather are incurred as a result
of overall production activities. In addition, some
production costs such as indirect materials cannot
be easily traced to jobs. If these costs are to be
assigned to products, they must be allocated to
the products.
2-8 If actual manufacturing overhead cost is
applied to jobs, the company must wait until the
end of the accounting period to apply overhead
and to cost jobs. If the company computes actual
overhead rates more frequently to get around this
problem, the rates may fluctuate widely due to
seasonal factors or variations in output. For this
reason, most companies use predetermined over-
head rates to apply manufacturing overhead costs
to jobs.
2-9 The measure of activity used as the allo-
cation base should drive the overhead cost; that
is, the allocation base should cause the overhead
cost. If the allocation base does not really cause
the overhead, then costs will be incorrectly at-
tributed to products and jobs and product costs
will be distorted.
2-10 Assigning manufacturing overhead costs
to jobs does not ensure a profit. The units pro-
duced may not be sold and if they are sold, they
may not be sold at prices sufficient to cover all
costs. It is a myth that assigning costs to prod-
ucts or jobs ensures that those costs will be re-
covered. Costs are recovered only by selling to
customers—not by allocating costs.

2-11 No, you would not expect the total ap-
plied overhead for a period to equal the actual
overhead for that period. This is because the ap-
plied overhead relies on a predetermined over-
head rate that is based on estimates in the nu-
merator and denominator.
2-12 When a company applied less overhead to
production than it actually incurs, it creates what
is known as underapplied overhead. When it
applies more overhead to production than it actu-
ally incurs, it results in overapplied overhead.
2-13 A plantwide overhead rate is a single
overhead rate used throughout a plant. In a mul-
tiple overhead rate system, each production de-
partment may have its own predetermined over-
head rate and its own allocation base. Some com-
panies use multiple overhead rates rather than
plantwide rates to more appropriately allocate
overhead costs among products. Multiple over-
head rates should be used, for example, in situa-
tions where one department is machine intensive
and another department is labor intensive.

1. When the total fixed manufacturing overhead cost for the Milling De-
partment is changed to $300,000, the worksheet changes as show be-
low:

The selling price of Job 407 has dropped from $4,348.75 to $4,112.50
because the fixed manufacturing overhead in the Milling Department de-
creased from $390,000 to $300,000. This reduced the predetermined
overhead rate in the Milling Department from $8.50 per machine-hour to
$7.00 per machine-hour and hence the amount of overhead applied to
Job 407 in the Milling Department.

2. For the new Job 408, the worksheet should look like the following:

3. When the total number of machine-hours in the Assembly Department
increases from 3,000 machine-hours to 6,000 machine-hours, the work-
sheet looks like the following:

The selling price for Job 408 is not affected by this change. The reason
for this is that the total number of machine-hours in the Assembly De-
partment has no effect on any cost. There would have been a change in
costs and in the selling price if the total machine-hours in the Milling De-
partment would have changed. This is because the predetermined over-
head rate in that department is based on machine-hours and any
change in the total machine-hours would affect the magnitude of the
predetermined overhead rate in that department.

4. When the total number of direct labor-hours in the Assembly Depart-
ment decreases from 80,000 direct labor-hours to 50,000 direct labor-
hours, the worksheet looks like the following:

The selling price of Job 408 has increased from $2,905.00 to $2,944.38.
This occurs because the decrease in the total number of direct labor-
hours in the Assembly Department increases the predetermined over-
head rate in that department from $10.00 per direct labor-hour to
$13.75 per direct labor-hour. In effect, the same total fixed manufactur-
ing overhead cost is spread across fewer total direct labor-hours.

1. The first step is to calculate the estimated total overhead costs in Mold-
ing and Fabrication:
Molding: Using the equation Y = a + bX, the estimated total manufac-
turing overhead cost is computed as follows:
Y = $10,000 + ($1.40 per MH)(2,500 MHs)
Estimated fixed manufacturing overhead .................. $10,000
Estimated variable manufacturing overhead:
$1.40 per MH × 2,500 MHs................................... 3,500

facturing overhead cost is computed as follows:
Y = $15,000 + ($2.20 per MH)(1,500 MHs)
$2.20 per MH × 1,500 MHs................................... 3,300
The second step is to combine the estimated manufacturing overhead
costs in Molding and Fabrication ($13,500 + $18,300 = $31,800) to en-
able calculating the predetermined overhead rate as follows:
Estimated total manufacturing overhead (a) . $31,800

3a. Given that the company is operating at 50% of its manufacturing ca-
pacity, an argument can made that the company should pursue any
business opportunities that generate a positive a contribution margin.

erate a positive contribution margin as shown below:

Variable overhead applied ($2.00 per MH × 72
MHs)............................................................ 144 2,124
Contribution margin......................................... $ 376

Exercise 2-9 (continued)
3b. The CFO’s argument is based on the assertion that Job P90 does not
generate enough revenue to cover the cost of the manufacturing re-
sources that it consumes. However, given that the company is operat-
ing at 50% of its manufacturing capacity, the overhead costs applied
to Job P90 in requirement 2 do not represent the cost of the overhead
resources consumed making Job P90. In other words, the overhead
applied in requirement 2 includes a charge for used and unused capac-
ity. This reality provides instructors an opportunity to introduce stu-
dents to the main idea underlying Appendix 2B.
If we estimate a capacity-based overhead rate for the company and
apply overhead costs to Job P90 using this rate, it reveals that the rev-
enue generated by the job ($2,500) is still insufficient to cover its man-
ufacturing costs of $2,556, as computed below:
The estimated total overhead cost (at capacity) is computed as follows
(keep in mind that 165,000 MHs ÷ 50% = 330,000 MHs):
Y = $1,980,000 + ($2.00 per MH)(330,000 MHs)
Estimated variable overhead: $2.00 per MH ×
330,000 MHs ...................................................... 660,000
The predetermined capacity-based overhead rate is computed as follows:
The total manufacturing cost assigned to Job P90 (using a capacity-based
overhead rate):
Direct labor ............................................................. 830
Overhead applied ($8 per MH × 72 MHs).................. 576
Total manufacturing cost..........................................
$2,556

1. Yes, overhead should be applied to Job W at year-end.
Because $6,000 of overhead was applied to Job V on the basis of
$8,000 of direct labor cost, the company’s predetermined overhead rate
must be 75% of direct labor cost.
Job W direct labor cost (a)............................................ $4,000
Predetermined overhead rate (b) .................................. 0.75
Manufacturing overhead applied to Job W (a) × (b) ....... $3,000
2. The direct materials ($2,500), direct labor ($4,000), and applied over-
head ($3,000) for Job W will be included in Work in Process on Sigma
Corporation’s balance sheet.

Note to the instructor: This exercise can be used as a launching pad for
a discussion of Appendix 2B.
1. The estimated total fixed manufacturing overhead can be computed us-
ing the data from any of quarters 1-3. For illustrative purposes, we’ll use
the first quarter as follows:
Total overhead cost (First quarter)........................... $300,000
Variable cost element ($2.00 per unit × 80,000 units) 160,000
Fixed cost element .................................................. $140,000
2. The fixed and variable cost estimates from requirement 1 can be used
to estimate the total manufacturing overhead cost for the fourth quarter
as follows:
Y = $140,000 + ($2.00 per unit)(60,000 units)
Estimated fixed manufacturing overhead ..................
Estimated variable manufacturing overhead
$140,000
$2.00 per unit × 60,000 units................................ 120,000
The estimated unit product cost for the fourth quarter
is computed as follows:
Direct materials .................................................... $180,000
Direct labor ........................................................ 96,000
Manufacturing overhead........................................ 260,000
Total manufacturing costs (a) .............................. $536,000
Number of units to be produced (b)..................... 60,000
Unit product cost (rounded) (a) ÷ (b) .................. $8.93

3. The fixed portion of the manufacturing overhead cost is causing the unit
product costs to fluctuate. The unit product cost increases as the level
of production decreases because the fixed overhead is spread over
fewer units.
4. The unit product cost can be stabilized by using a predetermined over-
head rate that is based on expected activity for the entire year. The cost
formula created in requirement 1 can be adapted to compute the annual
predetermined overhead rate. The annual fixed manufacturing overhead
is $560,000 ($140,000 per quarter × 4 quarters). The variable manufac-
turing overhead per unit is $2.00. The cost formula is as follows:
Y = $560,000 + ($2.00 per unit × 200,000 units)
$2.00 per unit × 200,000 units.............................. 400,000
The annual predetermined overhead rate is computed as follows:
Estimated total manufacturing overhead (a) $960,000
Estimated total units produced (b).............. 200,000
Predetermined overhead rate (a) ÷ (b)....... $4.80 per unit
Using a predetermined overhead rate of $4.80 per unit, the unit product
costs would stabilize as shown below:

Unit product cost (a) ÷ (b) $9.40 $9.40 $9.40 $9.40

1. The estimated total manufacturing overhead cost is computed as fol-
lows:
Y = $650,000 + ($3.00 per MH)(100,000 MHs)
Estimated fixed manufacturing overhead................. $650,000
per MH × 100,000 MHs ....................................... 300,000
Estimated total manufacturing overhead cost .......... $950,000
Estimated total manufacturing overhead (a) $950,000
2. Total manufacturing cost assigned to Job 400:
Direct materials ....................................................... $ 450
Direct labor ............................................................. 210
Manufacturing overhead applied ($9.50 per MH × 40
MHs).................................................................... 380
3. The unit product cost of Job 400 is computed as follows:
Total manufacturing cost (a)...................... $1,040
Number of units in the job (b).................... 52
Unit product cost (a) ÷ (b) ........................ $20
4. The selling price per unit is computed as follows:
Total manufacturing cost ........................... $1,040
Markup (120% of manufacturing cost) ....... 1,248
Selling price for Job 400 (a)....................... $2,288
Number of units in Job 400 (b) .................. 52
Selling price per unit (a) ÷ (b) ................... $44

5. Possible critiques of Moody’s pricing tactics include (1) relying on a
plantwide overhead rate to allocate overhead costs to jobs may distort
the cost base used for cost-plus pricing, (2) relying on an absorption ap-
proach may allocate unused capacity costs to jobs thereby distorting the
cost base for cost-plus pricing, and (3) relying on absorption cost-plus
pricing ignores the customers’ willingness to pay based on their per-
ceived value of the product or service.

ment is computed as follows:

3. Yes; if some jobs require a large amount of machine time and a small
amount of labor time, they would be charged substantially less overhead
cost if a plantwide overhead rate based on direct labor hours were used.
It appears, for example, that this would be true of Job 203 which re-
quired considerable machine time to complete, but required a relatively
small amount of labor hours.

Exercise 2-15 (45 minutes)
1a. The first step is to calculate the estimated total overhead costs in
Molding and Fabrication:
Molding: Using the equation Y = a + bX, the estimated total manufac-
turing overhead cost would be calculated as follows:
Y = $700,000 + ($3.00 per MH)(20,000 MHs)
Estimated fixed manufacturing overhead................... $700,000
per MH × 20,000 MHs........................................... 60,000
facturing overhead cost would be calculated as follows:
Y = $210,000 + ($1.00 per MH)(30,000 MHs)
per MH × 30,000 MHs........................................... 30,000
The second step is to combine the estimated manufacturing overhead
costs in Molding and Fabrication ($760,000 + $240,000 = $1,000,000)
to enable calculating the predetermined overhead rate as follows:
Estimated total manufacturing overhead (a) $1,000,000
Predetermined overhead rate (a) ÷ (b) ...... $20.00 per MH

1b. Total manufacturing cost assigned to Jobs D-70 and C-200:
Direct materials .........................................
D-70
$ 700,000
C-200
$ 550,000
Direct labor ............................................... 360,000 400,000
Manufacturing overhead applied ($20.00
per MH × 20,000 MHs; $20.00 per MH ×
30,000 MHs)........................................... 400,000 600,000
Total manufacturing cost............................ $1,460,000 $1,550,000
1c. Bid prices for Jobs D-70 and C-200:
D-70 C-200
Total manufacturing cost (a) ...................... $1,460,000 $1,550,000
Markup percentage (b) .............................. 150% 150%
Bid price (a) × (b) ..................................... $2,190,000 $2,325,000
1d. Because the company has no beginning or ending inventories and
only Jobs D-70 and C-200 were started, completed, and sold during
the year, the cost of goods sold is equal to the sum of the manufac-
turing costs assigned to both jobs of $3,010,000 (=$1,460,000 +
$1,550,000).

2a. Molding Department:
Using the equation Y = a + bX, the estimated total manufacturing over-
head cost would be depicted as follows:
Y = $700,000 + ($3.00 per MH)(20,000 MHs)

Estimated total manufacturing overhead cost ............ $760,000
Estimated total manufacturing overhead (a). $760,000
Predetermined overhead rate (a) ÷ (b) ........ $38.00 per MH
Fabrication Department:
Using the equation Y = a + bX, the estimated total manufacturing over-
head cost would be depicted as follows:
Y = $210,000 + ($1.00 per MH)(30,000 MHs)
per MH × 30,000 MHs........................................... 30,000
Estimated total manufacturing overhead cost ............ $240,000
Estimated total manufacturing overhead (a). $240,000
Estimated total direct labor-hours (b)........... 30,000 MHs

Direct labor...................................................... 360,000 400,000
Molding Department (14,000 MHs × $38 per
MH; 6,000 MHs × $38 per MH)....................... 532,000 228,000
Fabrication Department (6,000 MH × $8 per
MH; 24,000 MH × $8 per MH) ........................ 48,000 192,000
Total manufacturing cost .................................. $1,640,000 $1,370,000
2c. Bid prices for Jobs D-70 and C-200:
D-70 C-200
Total manufacturing cost (a) ....................... $1,640,000 $1,370,000
Markup percentage (b) ............................... 150% 150%
Bid price (a) × (b) ...................................... $2,460,000 $2,055,000
2d. Because the company has no beginning or ending inventories and
only Jobs D-70 and C-200 were started, completed, and sold during
the year, the cost of goods sold is equal to the sum of the manufac-
turing costs assigned to both jobs of $3,010,000 (=$1,640,000 +
$1,370,000).
3. The plantwide and departmental approaches for applying manufacturing
overhead costs to products produce identical cost of goods sold figures.
However, these two approaches lead to different bid prices for Jobs D-
70 and C-200. The bid price for Job D-70 using the departmental ap-
proach is $270,000 (=$2,460,000 ‒ $2,190,000) higher than the bid
price using the plantwide approach. This is because the departmental
cost pools reflect the fact that Job D-70 is an intensive user of Molding
machine-hours. The overhead rate in Molding ($38) is much higher than
the overhead rate in Fabrication ($8). Conversely, Job C-200 is an inten-
sive user of the less-expensive Fabrication machine-hours, so its depart-
mental bid price is $270,000 lower than the plantwide bid price.

Whether a job-order costing system relies on plantwide overhead cost allo-
cation or departmental overhead cost allocation does not usually have an
important impact on the accuracy of the cost of goods sold reported for the
company as a whole. However, it can have a huge impact on internal deci-
sions with respect to individual jobs, such as establishing bid prices for
those jobs. Job-order costing systems that rely on plantwide overhead cost
allocation are commonly used to value ending inventories and cost of
goods sold for external reporting purposes, but they can create costing in-
accuracies for individual jobs that adversely influence internal decision
making.

1a. The estimated total overhead cost is computed as follows:
Y = $784,000 + ($2.00 per DLH)(140,000 DLHs)
Estimated fixed manufacturing overhead................. $ 784,000
per DLH × 140,000 DLH...................................... 280,000

2c. The selling price for Job 550 is computed as follows:
Job 550
Markup (200%)....................................................... 952
Selling price ............................................................ $1,428
3. The price for Job 550 using direct labor-hours as the allocation base
($1,542) is $114 higher than the price derived using machine-hours as
the allocation base ($1,428). If machine-hours is the better choice for
an allocation base, then if Landen continues to use direct labor-hours as
its overhead allocation base, it will overprice jobs that are intensive us-
ers of direct labor-hours and non-intensive users of machine-hours. In a
bidding situation, Landen will tend to lose bids on jobs such as Job 550
if its competitors have more accurate cost accounting systems.

1a. The first step is to calculate the total estimated overhead costs in ICU
and Other:
ICU: Using the equation Y = a + bX, the estimated total overhead cost
would be calculated as follows:
Y = $3,200,000 + ($236 per patient-day)(2,000 patient-days)
Estimated fixed overhead.................................... $3,200,000
Estimated variable overhead:
$236 per patient-day × 2,000 patient-days........ 472,000
Estimated total overhead cost ............................. $3.672,000
Other: Using the equation Y = a + bX, the estimated total overhead cost
would be calculated as follows:
Estimated fixed overhead .................................... $14,000,000
$96 per patient-day × 18,000 patient-days ........ 1,728,000
Estimated total overhead cost.............................. $15.728,000
The second step is to combine the estimated overhead costs in ICU and
Other ($3,672,000 + $15,728,000 = $19,400,000) to enable calculating the
predetermined overhead rate as follows:
Estimated total overhead (a)............... $19,400,000
Estimated total patient-days (b) .......... 20,000 patient-days
Predetermined overhead rate (a) ÷ (b) $970 per patient-day

1b. The total cost assign to Patients A and B is computed as follows:
Patient A Patient B
Direct materials...................................... $ 4,500 $ 6,200
Direct labor............................................ 25,000 36,000
Overhead applied ($970 per patient-day
× 14 patient days; ($970 per patient-
day × 21 patient days) ........................ 13,580 20,370
Total cost .............................................. $43,080 $62,570
2a. The overhead rate in ICU is computed as follows:
Estimated fixed overhead.................................... $3,200,000
$236 per patient-day × 2,000 patient-days........ 472,000
Estimated total overhead cost ............................. $3,672,000
Estimated total overhead (a) ............... $3,672,000
Estimated total patient-days (b)........... 2,000 patient-days
Predetermined overhead rate (a) ÷ (b) $1,836 per patient-day
The overhead rate in Other is computed as follows:
Estimated fixed overhead .................................... $14,000,000
$96 per patient-day × 18,000 patient-days ........ 1,728,000
Estimated total overhead cost.............................. $15,728,000
Estimated total overhead (a) ............... $15,728,000
Estimated total patient-days (b)........... 18,000 patient-days
Predetermined overhead rate
(rounded) (a) ÷ (b).......................... $873.78 per patient-day

2b.The total cost assigned to Patient A:
Direct materials................................................ $ 4,500
Direct labor...................................................... 25,000
ICU ($1,836 per patient-day × 0 patient-days)... $ 0
Other ($873.78 per patient day × 14 patient-
days) (rounded to nearest dollar) ................... 12,233 12,233
Total cost assigned to Patient A ........................ $41,733
The total cost assigned to Patient B:
Direct materials................................................ $ 6,200
Direct labor...................................................... 36,000
ICU ($1,836 per patient-day × 7 patient-days)... $12,852
Other ($873.78 per patient day × 14 patient-
days) (rounded to nearest dollar) ................... 12,233 25,085
Total cost assigned to Patient B ........................ $67,285
3. Relying on just one predetermined overhead rates overlooks the fact
that some departments are more intensive users of overhead resources
than others. As the name implies, patients in the ICU require more in-
tensive (and expensive) care than other patients in other departments.
Broadly, speaking, relying on only one overhead rate, will most likely
overcost patients with less severe illnesses and undercost patients with
more severe illnesses.

Problem 2-21 (30 minutes)
1. The plantwide predetermined overhead rate is computed as follows:
Predetermined overhead rate (a) ÷ (b)....... $10 per DLH
The overhead applied to Job A is computed as follows:
Direct labor-hours worked on Job A (a) ...... 15
Predetermined overhead rate (b) ............... $10 per DLH
Overhead applied to Job A (a) × (b)........... $150
The overhead applied to Job B is computed as follows:
Direct labor-hours worked on Job B (a) ...... 9
Predetermined overhead rate (b) ............... $10 per DLH
Overhead applied to Job B (a) × (b)........... $90
2. The predetermined overhead rate in Machining is computed as follows:
Predetermined overhead rate (a) ÷ (b)....... $10 per MH
The predetermined overhead rate in Assembly is computed as follows:
Predetermined overhead rate (a) ÷ (b)....... $2 per DLH
The overhead applied to Job A is computed as follows:
Machining Assembly Total
Quantity of allocation base used (a) . 11 10
Predetermined overhead rate (b) ..... $10 $2
Overhead applied to Job A (a) × (b). $110 $20 $130

Problem 2-21 (continued)
The overhead applied to Job B is computed as follows:
Machining Assembly Total
Quantity of allocation base used (a) . 12 5
Predetermined overhead rate (b) ..... $10 $2
Overhead applied to Job B (a) × (b). $120 $10 $130
3. The plantwide approach will overcost jobs that are intensive users of As-
sembly and minimal users of Machining. Conversely, it will undercost
products that are intensive users of Machining and minimal users of As-
sembly. These cost distortions will adversely impact the company’s pric-
ing process. Jobs that get overcosted will have selling prices that are
greater than the prices that would be established using departmental
overhead allocation. Jobs that get undercosted will have selling prices
that are less than the prices that would be established using depart-
mental overhead allocation.

$500 × 400% ............................... 2,000
Assembly Department:
$6,200 × 30% .............................. 1,860
Total applied overhead..................... $8,760
3. The bulk of the labor cost on the Koopers job is in the Assembly Depart-
ment, which incurs very little overhead cost. The department has an
overhead rate of only 30% of direct labor cost as compared to much
higher rates in the other two departments. Therefore, as shown above,
use of departmental overhead rates results in a relatively small amount
of overhead cost being charged to the job.
Use of a plantwide overhead rate in effect redistributes overhead costs
proportionately between the three departments (at 140% of direct labor

Case 2-22 (continued)
cost) and results in a large amount of overhead cost being charged to
the Koopers job, as shown in Part 1. This may explain why the company
bid too high and lost the job. Too much overhead cost was assigned to
the job for the kind of work being done on the job in the plant.
On jobs that require a large amount of labor in the Fabricating or Ma-
chining Departments the opposite will be true, and the company will
tend to charge too little overhead cost to the jobs if a plantwide over-
head rate is being used. The reason is that the plantwide overhead rate
(140%) is much lower than the rates would be if these departments
were considered separately.
4. The company’s bid was:
Direct labor................................................. 9,500
Manufacturing overhead applied (see require-
ment 1b).................................................. 13,300
Total manufacturing cost ............................. $27,400
Bidding rate ................................................ × 1.5
Total bid price............................................. $41,100
If departmental overhead rates had been used, the bid would have
been:
Direct labor................................................. 9,500
Manufacturing overhead applied (see require-
ment 2b).................................................. 8,760
Total manufacturing cost ............................. $22,860
Bidding rate ................................................ × 1.5
Total bid price............................................. $34,290
Note that if departmental overhead rates had been used, Teledex Com-
pany would have been the low bidder on the Koopers job because the
competitor underbid Teledex by only $2,000.

3. The unit product cost of the high-volume product, Parcel, declines under
the activity-based approach, whereas the unit product cost of the low-
volume product, Rascon, increases. This occurs because half of the
overhead is applied on the basis of engineering design hours instead of
direct labor-hours. When the overhead was applied on the basis of di-
rect labor-hours, most of the overhead was applied to the high-volume
product. However, when the overhead is applied on the basis of engi-
neering-hours, more of the overhead cost is shifted over to the low-vol-
ume product. Engineering-hours is a product-level activity, so the higher
the volume, the lower the unit cost and the lower the volume, the
higher the unit cost.

Overhead cost per unit (a) ÷ (b)......... $39.50

b. The unit product cost of each model under the activity-based ap-
proach would be computed as follows:
Model
X200 X99
Direct materials ..................................... $ 72.00 $50.00
Direct labor:
$20 per DLH × 1.8 DLHs, 0.9 DLHs...... 36.00 18.00
Manufacturing overhead (above) ............ 123.00 39.50
Total unit product cost........................... $231.00 $107.50
Comparing these unit cost figures with the unit costs in Part 1(b), we
find that the unit product cost for Model X200 has increased from
$198 to $231, and the unit product cost for Model X99 has decreased
from $113 to $107.50.
3. It is especially important to note that, even under activity-based costing,
70% of the company’s overhead costs continue to be applied to prod-
ucts on the basis of direct labor-hours:
Machine setups (number of setups)... $ 360,000 20%
Special processing (machine-hours)... 180,000 10
General factory (direct labor-hours)... 1,260,000 70
Total overhead cost.......................... $1,800,000 100%
Thus, the shift in overhead cost from the high-volume product (Model
X99) to the low-volume product (Model X200) occurred as a result of re-
assigning only 30% (=20% + 10%) of the company’s overhead costs.
The increase in unit product cost for Model X200 can be explained as
follows: First, where possible, overhead costs have been traced to the
products rather than being lumped together and spread uniformly over
production. Therefore, the special processing costs, which are traceable
to Model X200, have all been assigned to Model X200 and none as-
signed to Model X99 under the activity-based approach. It is common in
industry to have some products that require special handling or special
processing of some type. This is especially true in modern factories that
produce a variety of products. Activity-based costing provides a vehicle
for assigning these costs to the appropriate products.

Second, the costs associated with the batch-level activity (machine set-
ups) have also been assigned to the specific products to which they re-
late. These costs have been assigned according to the number of setups
completed for each product. However, because a batch-level activity is
involved, another factor affecting unit costs comes into play. That factor
is batch size. Some products are produced in large batches and some
are produced in small batches. The smaller the batch, the higher the per
unit cost of the batch activity. In the case at hand, the data can be ana-
lyzed as follows:
Model X200:
Cost to complete one setup (see requirement 2a)........ $2,400 (a)
Number of units processed per setup
(5,000 units per setup ÷ 50 setups = 100 units)....... 100 units (b)
Setup cost per unit (a) ÷ (b)...................................... $24
Model X99:
Cost to complete one setup (see requirement 2a)........ $2,400 (a)
Number of units processed per setup
(30,000 units per setup ÷ 100 setups = 300 units) ... 300 units (b)
Setup cost per unit (a) ÷ (b)...................................... $8
Thus, the cost per unit for setups is three times as great for Model
X200, the low-volume product, as it is for Model X99, the high-volume
product. Such differences in cost are obscured when direct labor-hours
(or any other volume measure) is used as a basis for applying overhead
cost to products.
In sum, overhead cost has shifted from the high-volume product to the
low-volume product as a result of more appropriately assigning some
costs to the products on the basis of the activities involved, rather than
on the basis of direct labor-hours.

Problem 2A-5 (60 minutes)
1. The company’s estimated direct labor-hours can be computed as fol-
lows:
Deluxe model: 5,000 units × 2 DLHs per unit .... 10,000 DLHs
Regular model: 40,000 units × 1 DLH per unit... 40,000 DLHs
Total direct labor hours .................................... 50,000 DLHs
Using just direct labor-hours as the base, the predetermined overhead
rate would be:
Estimated overhead cost
=
$900,000
= $18 per DLH
Estimated direct labor-hours 50,000DLHs
The unit product cost of each model using the company’s traditional

b. Using activity-based absorption costing, the unit product cost of each
model would be:
Deluxe Regular
Direct materials.......................... $ 40.00 $25.00
Direct labor................................ 38.00 19.00
Manufacturing overhead (above). 79.80 12.53
Total unit product cost................ $157.80 $56.53
4. Unit costs appear to be distorted as a result of using direct labor-hours
as the base for assigning overhead cost to products. Although the
deluxe model requires twice as much labor time as the regular model, it
still is not being assigned enough overhead cost, as shown in the analy-
sis in part 3(a).
When the company’s overhead costs are analyzed on an activities basis,
it appears that the deluxe model is more expensive to manufacture than
the company realizes. Note that the deluxe model accounts for a major-
ity of the machine-hours worked, even though it accounts for only 20%
(= 10,000 DLHs ÷ 50,000 DLHs) of the company’s direct labor-hours.
Also, it requires just as many scrap/rework orders as the regular model,
and scrap/rework orders are very costly to the company.
When activity-based absorption costing is used and the company’s
transactions are analyzed by product, the overhead cost increases for
the deluxe model from $36.00 per unit to $79.80 per unit. This suggests
that less than half the overhead cost is being assigned to the deluxe
model that ought to be assigned, and unit costs for the deluxe model
are understated. If these costs are being used as a basis for pricing,
then the selling price for the deluxe model may be too low. This may be
the reason why profits have been steadily declining over the last several
years. It may also be the reason why sales of the deluxe model have
been increasing rapidly.

(a)

Before we can determine the amount of overhead cost to assign to
the products we must first determine the activity for each of the
products in the six activity centers. The necessary computations fol-
low:
Number of purchase orders:
Kenya Dark: 80,000 pounds ÷ 20,000 pounds per order = 4 orders
Viet Select: 4,000 pounds ÷ 500 pounds per order = 8 orders
Number of setups:
Kenya Dark: (80,000 pounds ÷ 5,000 pounds per batch) × 2 setups
per batch = 32 setups
Viet Select: (4,000 pounds ÷ 500 pounds per batch) × 2 setups per
batch = 16 setups
Number of batches:
Kenya Dark: 80,000 pounds ÷ 5,000 pounds per batch = 16 batches
Viet Select: 4,000 pounds ÷ 500 pounds per batch = 8 batches
Roasting hours:
Kenya Dark: 1.5 hours × (80,000 pounds ÷ 100 pounds) = 1,200
hours
Viet Select: 1.5 hours × (4,000 pounds ÷ 100 pounds) = 60 hours
Blending hours:
Kenya Dark: 0.5 hour × (80,000 pounds ÷ 100 pounds) = 400 hours
Viet Select: 0.5 hour × (4,000 pounds ÷ 100 pounds) = 20 hours
Packaging hours:
Kenya Dark: 0.3 hour × (80,000 pounds ÷ 100 pounds) = 240 hours

3. MEMO TO THE PRESIDENT: Analysis of JSI’s data shows that several
activities other than direct labor drive the company’s manufacturing
overhead costs. These activities include purchase orders issued, number
of setups for material processing, and number of batches processed.
The company’s present costing system, which relies on direct labor time
as the sole basis for assigning overhead cost to products, significantly
undercosts low-volume products, such as the Viet Select coffee, and sig-
nificantly overcosts high-volume products, such as our Kenya Dark cof-
fee.
An implication of the activity-based approach is that our low-volume
products may not be covering the costs of the manufacturing resources
they use. For example, Viet Select coffee is currently priced at $5.15 per
pound ($4.12 plus 25% markup), which is only one cent higher than its
activity-based cost of $5.14 per pound. Under our present costing and
pricing system, our high-volume products, such as our Kenya Dark cof-
fee, may be subsidizing our low-volume products. Some adjustments in
prices may be required.

Case 2A-6 (continued)
ALTERNATIVE SOLUTION:
Most students will compute the manufacturing overhead cost per pound
of the two coffees as shown above. However, the per pound cost can
also be computed as shown below. This alternative approach provides
additional insight into the data and facilitates emphasis of some points
made in the chapter.
Kenya Dark Viet Select
Total
Per Pound
(÷ 80,000) Total
Per Pound
(÷ 4,000)
Purchasing........... $ 1,120 $0.014 $2,240 $0.560
Material handling.. 6,176 0.077 3,088 0.772
Quality control ..... 2,880 0.036 1,440 0.360
Roasting .............. 13,200 0.165 660 0.165
Blending .............. 2,400 0.030 120 0.030
Packaging............ 1,200 0.015 60 0.015
Total ................... $26,976 $0.337 $7,608 $1.902
Note particularly how batch size impacts unit cost data. For example, the
cost to the company to process a purchase order is $280, regardless of
how many pounds of coffee are contained in the order. Twenty thousand
pounds of the Kenya Dark coffee are purchased per order (with four orders
per year), and just 500 pounds of the Viet Select coffee are purchased per
order (with eight orders per year). Thus, the purchase order cost per
pound for the Kenya Dark coffee is just 1.4 cents, whereas the purchase
order cost per pound for the Viet Select coffee is 40 times as much, or 56
cents. As stated in the text, this is one reason why unit costs of low-vol-
ume products, such as the Viet Select coffee, increase so dramatically
when activity-based costing is used.

Appendix 2B
The Predetermined Overhead Rate
and Capacity
Exercise 2B-1 (20 minutes)
1. There were no beginning or ending inventories, so all of the jobs were
started, finished, and sold during the month. Therefore cost of goods
sold equals the total manufacturing cost. We can verify that by compu-
ting the cost of goods sold as shown below:
Manufacturing costs charged to jobs:
Direct labor (all variable)..............................
Manufacturing overhead applied
(150 hours × $82 hour) ............................
8,860
12,300
Total manufacturing cost charged to jobs........ 26,510
Add: Beginning work in process inventory ....... 0
26,510
Deduct: Ending work in process inventory ....... 0
Cost of goods manufactured........................... $26,510
Beginning finished goods inventory................. $ 0
Add: Cost of goods manufactured ................... 26,510
Goods available for sale.................................. 26,510
Deduct: Ending finished goods inventory......... 0
Cost of goods sold ......................................... $26,510
At the end of the month, the cost of unused capacity is computed as
shown below:
Amount of the allocation base at capacity (a) . 180 hours
Actual amount of the allocation base (b) ........ 150 hours
Unused capacity in hours (a) – (b)................. 30 hours
Unused capacity in hours (a) ......................... 30 hours
Predetermined overhead rate (b) ................... $82 per hour
Cost of unused capacity (a) × (b) .................. $2,460

Consequently, the income statement, prepared for internal management
purposes, would appear as follows:
Wixis Cabinets
Income Statement
Sales.................................................... $43,740
Cost of goods sold (see above).............. 26,510
Gross margin ........................................ 17,230
Other expenses:
Cost of unused capacity...................... $2,460
Selling and administrative expenses .... 8,180 10,640
Net operating income............................ $ 6,590
2. When the predetermined overhead rate is based on capacity, unused
capacity costs ordinarily arise because manufacturing overhead usually
contains significant amounts of fixed costs. Suppose, for example, that
manufacturing overhead includes $10,000 of fixed costs and the capac-
ity is 100 hours. Then the portion of the predetermined overhead rate
that represents fixed costs is $10,000 divided by 100 hours or $100 per
hour. Because the plant is seldom (if ever) operated beyond capacity,
less than $10,000 will ordinarily be applied to jobs. In other words, $100
per hour multiplied by something less than 100 hours always yields less
than $10,000. Therefore, unused capacity costs will arise.

Predetermined overhead rate (b)........................ $51.75 $51.75
Cost of unused capacity (a) × (b)....................... $72,450 $77,625
Proponents of this method of computing predetermined overhead rates
suggest that the cost of unused capacity should be treated as a period
expense that is disclosed separately on the income statement.

Unused capacity in hours (a) – (b)...................... 850 1,100
Unused capacity in hours (a).............................. 850 1,100
Predetermined overhead rate (b)........................ $100 $100
Cost of unused capacity (a) × (b)....................... $85,000 $110,000
Proponents of this method suggest that the cost of unused capacity should
be treated as a period expense that is disclosed separately on the income
statement.

Problem 2B-3 (continued)
4. Platinum Track’s fundamental problem is the competition that is drawing
customers away. The competition is able to offer the latest equipment,
excellent service, and attractive prices. The company must do some-
thing to counter this threat or it will ultimately face failure.
Under the conventional approach in which the predetermined overhead
rate is based on the estimated studio hours, the apparent cost of the
Verde Baja job has increased between last year and this year. That hap-
pens because the company is losing business to competitors and there-
fore the company’s fixed overhead costs are being spread over a smaller
base. This results in costs that seem to increase as the volume declines.
Under this method, Platinum Track’s managers may be misled into
thinking that the problem is rising costs and they may be tempted to
raise prices to recover their apparently increasing costs. This would al-
most surely accelerate the company’s decline.
Under the alternative approach, the overhead cost of the Verde Baja job
is stable at $4,000 and lower than the costs reported under the conven-
tional method. Under the conventional method, managers may be mis-
led into thinking that they are actually losing money on the Verde Baja
job and they might refuse such jobs in the future—another sure road to
disaster. This is much less likely to happen if the lower cost of $4,000 is
reported. It is true that the cost of unused capacity under the alterna-
tive approach is much larger than under the conventional approach and
is growing. However, if it is properly labeled as the cost of unused ca-
pacity, management is much more likely to draw the appropriate conclu-
sion that the real problem is the loss of business (and therefore more
idle capacity) rather than an increase in costs.
While basing the predetermined rate on capacity rather than on esti-
mated activity will not solve the company’s basic problems, at least this
method is less likely to send managers misleading signals.

Vault Hard Drives, Inc.
Income Statement: New Approach
Sales (150,000 units × $60 per unit) ................... $9,000,000
Cost of goods sold:
Variable manufacturing
(150,000 units × $15 per unit)....................... $2,250,000
(150,000 units × $20 per unit)....................... 3,000,000 5,250,000

Cost of unused capacity [(200,000 units –
160,000 units) × $20 per unit]....................... 800,000
Selling and administrative expenses.................. 2,700,000
Net operating income ......................................... $ 250,000

Case 2B-4 (continued)
2. Under the traditional approach, all of the company’s fixed manufacturing
overhead must be included in either cost of goods sold (in the income
statement) or ending inventory (in the balance sheet) at the end of an
accounting period. For each additional unit produced but not sold, it en-
ables the company to include an extra $25 of fixed overhead in ending
inventory, which in turn lowers the company’s cost of goods sold by
$25.
Since the company has net operating income of $300,000 when it pro-
duces 160,000 units and sells 150,000 units, it needs to produce enough
additional units, beyond 160,000 units, to raise net operating by
$200,000 to achieve a desired profit of $500,000. The following compu-
tations show that the company would need to produce 8,000 more units
(or 168,000 units in total) to achieve net operating income of $500,000.
Additional net operating income required to attain target
net operating income ($500,000 – $300,000) (a)......... $200,000
Fixed overhead applied to each unit of additional inven-
tory (b) ..................................................................... $25 per unit
Additional output required to attain target net operating
income (a) ÷ (b)........................................................ 8,000 units
Estimated number of units produced .............................. 160,000 units
Actual number of units to be produced ........................... 168,000 units
* Although overapplied overhead is not explored in detail until the next
chapter, astute students may be curious to know that this answer of
168,000 units assumes that the overapplied overhead of $200,000 is closed
entirely to Cost of Goods Sold.

Case 2B-4 (continued)
3. Under the new approach, all of the company’s fixed manufacturing
overhead must be included in either cost of goods sold (in the income
statement), ending inventory (in the balance sheet), or cost of unused
capacity (in the income statement) at the end of an accounting period.
For each additional unit produced but not sold, it enables the company
to include an extra $20 of fixed overhead in ending inventory, which in
turn lowers the company’s cost of unused capacity by $20.
Since the company has net operating income of $250,000 when it pro-
duces 160,000 units and sells 150,000 units, it needs to produce
enough additional units, beyond 160,000 units, to raise net operating
by $250,000 to achieve a desired profit of $500,000. The computations
below show that the company would need to produce 12,500 more
units (or 172,500 units in total) to achieve net operating income of
$500,000.
Additional net operating income required to attain target
net operating income ($500,000 – $250,000) (a)........... $250,000
Fixed overhead applied to each unit of additional inven-
tory (b) ....................................................................... $20 per unit
Additional output required to attain target net operating
income (a) ÷ (b).......................................................... 12,500 units
Estimated number of units produced ............................... 160,000 units
Actual number of units to be produced ............................ 172,500 units
4. Net operating income is more volatile under the new method than under
the old method. The reason for this is that the reported profit per unit
sold is higher under the new method by $5, the difference in the prede-
termined overhead rates. As a consequence, swings in sales in either di-
rection will have a more dramatic impact on reported profits under the
new method.

5. The “hat trick” is a bit harder to perform under the new method. Under
the old method, the target net operating income can be attained by pro-
ducing an additional 8,000 units. Under the new method, the production
would have to be increased by 12,500 units. Again, this is a conse-
quence of the difference in predetermined overhead rates. The drop in
sales has had a more dramatic effect on net operating income under the
new method as noted above in part (4). In addition, because the prede-
termined overhead rate is lower under the new method, producing ex-
cess inventories has less of an effect per unit on net operating income
than under the traditional method and hence more excess production is
required.
6. One can argue that whether the “hat trick” is unethical depends on the
level of sophistication of the owners of the company and others who
read the financial statements. If they understand the effects of excess
production on net operating income and are not misled, it can be ar-
gued that the hat trick is not unethical. However, if that were the case,
there does not seem to be any reason to use the hat trick. Why would
the owners want to tie up working capital in inventories just to artifi-
cially attain a target net operating income for the period? And increasing
the rate of production toward the end of the year is likely to increase
overhead costs due to overtime and other costs. Building up inventories
all at once is very likely to be much more expensive than increasing the
rate of production uniformly throughout the year. In this case, we as-
sumed that there would not be an increase in overhead costs due to the
additional production, but that is likely not to be true.
In our opinion, the hat trick is unethical unless there is a good reason
for increasing production other than to artificially boost the current pe-
riod’s net operating income. It is certainly unethical if the purpose is to
fool users of financial reports such as owners and creditors or if the pur-
pose is to meet targets so that bonuses will be paid to top managers.
