Cost Allocation and Activity-Based Costing
1. Indirect costs are allocated to (1) provide information for decision making, (2) reduce
frivolous use of common resources, (3) encourage evaluation of internally provided
services, and (4) calculate the “full cost” of products for GAAP reporting.
2. The statement is false. Cost allocation refers to the process of assigning indirect costs.
Direct costs are traced to cost objects. Costs are allocated for a variety of reasons. It is not
economically feasible to directly trace some costs to cost objects—these costs are classified
as indirect costs and are allocated to the cost object via the use of an allocation base.
3. Charging for internal services can reduce frivolous use of resources and encourage
departments being charged to critically evaluate the service. In addition, GAAP requires
that all manufacturing costs be assigned to goods being produced. Thus, cost allocation of
indirect manufacturing costs is required.
4. Cost-plus contracts specify that the contractor will be paid for the cost of production (or
services) plus some fixed amount or percentage of cost. Defense contracts with the federal
government are often cost-plus contracts.
A major problem with cost-plus contracts is that they give the contractor an incentive to
allocate as much cost as possible to the cost-plus contract (via the choice of an allocation
base) where it will be reimbursed.
5. A cost objective is a product, service, or department that receives an allocation of cost. For
example, a production department that receives an allocation of janitorial cost is a cost
objective. Likewise, a product in a department that receives an allocation of depreciation of
equipment is a cost objective.
6. A cost pool is a collection of individual indirect costs whose total is allocated using one
allocation base. Cost pools are often formed along department lines. For example, the
maintenance cost pool would include all costs of the maintenance department.
7. A concern in forming a cost pool is that the costs within the cost pool be similar or
homogeneous. It is unlikely that variable and fixed costs are similar (i.e., that one
allocation base is suitable for allocating both fixed and variable costs). Homogeneous cost
pools provide more accurate information.

8. Number of employees in a department would, most likely, result in a cause-and-effect
allocation (at least for the variable costs in the cafeteria).
9. (1) Benefits received (relative benefits)
(2) Ability to bear costs
(3) Equity or fairness
10. If budgeted costs are allocated, then service departments cannot pass on inefficiencies and
waste. Allocating actual costs gives the service department little incentive to be efficient.
11. In a responsibility accounting system, revenues and costs are traced to departments/
divisions and individuals with related responsibility for generating revenues and controlling
costs. This facilitates performance evaluation of managers and the operations under their
12. Sometimes managers are allocated costs beyond their control in order to make them aware
that the cost exist and must be covered by revenues of the firm.
13. Unitizing fixed costs make them appear to be variable. If the unitized fixed costs are then
allocated to divisions based on, for example, revenue, divisional managers may make
decisions in order to maximize divisional profits that are not in the company’s best interest.
This problem can be avoided by lump-sum allocations of fixed costs.
14. Traditional allocation methods use a small number of cost pools and allocation bases
related to production volume. However, some costly activities are not related to production
volume. Consider the costs associated with setups—in a traditional costing system setup
costs would be allocated based on production volume and high volume products will
receive most of the allocated cost even though low volume products may require an equal
number of setups.
15. The traditional costing approach typically uses allocation bases that are measures of
production volume (e.g., direct labor hours, direct labor cost, or machine hours). Also, few
cost pools are used under the traditional approach (e.g., one or two cost pools).
ABC focuses on major activities that cause overhead costs to be incurred. Many of these
activities are not related to production volume. Cost pools are formed for each major
activity and costs are assigned to products using an allocation base that is a cost driver.
Many of the cost drivers are not related to production volume. ABC typically uses more
cost pools and related cost drivers.
Chapter 6 Cost Allocation and Activity-Based Costing 6-3
16. ABC will tend to give more accurate costs than a traditional cost system when:
(1) the production process is complex and varied (high and low volume products),
(2) products consume resources differently, and
(3) there are activities that are not related to production volume (e.g., setups).
17. (1) ABC is more costly to develop and maintain than a traditional system.
(2) In practice, ABC is used to develop the full cost of products. The ABC cost per unit
does not measure the incremental costs needed to produce an item. Therefore, it is not
always useful for decision making.
18. ABC focuses on activities with the goal of measuring costs of products and services
produced by the firm. ABM focuses on activities with the goal of managing the activities
themselves. ABC has the goal of accurately computing costs of products and services while
ABM focuses on reducing the costs of or the demand for major activities.

E1. Fixed costs (e.g., administrative costs) are sometimes allocated based on a
measure of business activity (e.g., sales). This makes the costs appear to be
variable (e.g., the higher sales, the higher the allocation of administrative
cost). In turn, this may lead to poor decisions if managers treat the allocated
costs as incremental.
E2. This allocation is potentially harmful. A hotel manager will tend to
overestimate the costs that increase with revenue. And this may lead to poor
decisions that affect revenue. For example, suppose a hotel manager is
considering a trade association’s request for a special convention rate of $70
per room during a slow season. The manager estimates that variable costs per
room are $75 including $10 of allocated costs for general administration. In
this case, the manager will turn down the request even though his or her
company would really make $5 of incremental profit per room. Remember,
$10 of allocated costs appear variable but, in fact, are fixed. Thus, actual
incremental costs are only $65, which is $5 less than incremental revenue of
E3. According to Table 1 displayed at this Web site, building depreciation is
allocated based on square footage, telecommunications costs are allocated
based on number of phone numbers (referred to as direct telephone ID), and
administrative and general costs are allocated based on a unit’s total expense
as a percent of the total expense of all units.
These allocations are not “cause and effect” allocations. Consider building
depreciation. When a unit occupies space, it doesn’t cause cost equal to
allocated depreciation. It may be that the space wasn’t occupied, in which
case no cost was caused. Or, occupancy may have led to a need to rent
additional space, causing a cost much higher than allocated depreciation.
Rather, the allocations are based on “relative benefit.” Thus, for example, if
you occupied space you benefited! And the assumption is that your benefit
was proportionate to space occupied.
E4. Star might want to encourage department managers to evaluate security
services. When security costs are allocated, departments have an incentive to
Chapter 6 Cost Allocation and Activity-Based Costing 6-5
voice concerns about the cost of security service. This may make the security
department more efficient. In addition, allocation of security costs that relate
to manufacturing are required under GAAP.
E5. a. Service Department Allocation Base
Human resources Number of employees
Duplicating Number of pages copied
Janitorial Floor space
Accounting Number of sales transactions
Graphic design Time spent on design work
Food services Number of employees
b. Under the direct method costs are not allocated between service
departments. Thus, the Human Resource department would not receive a
share of Food Services costs.
E6. Total fixed costs to be allocated = $60,000 + 15,000 + 15,000 + 2,000 =
Fixed costs allocated to Sales ($92,000 × .3) $ 27,600
Variable costs allocated to Sales (1,500,000 copies × $.02) 30,000
Total costs allocated to Sales $ 57,600
Fixed costs allocated to Admin. ($92,000 × .7) $ 64,400

Square footage $1,200,000 $1,800,000
Direct labor hrs. $1,800,000 $1,200,000
(1) As indicated, the choice of the allocation base greatly affects the
allocations of cost. Use of square footage as the allocation base assigns 60%
of the cost to department 2 and 40% to department 1. However, use of direct
labor hours allocates 60% of the cost to department 1 and only 40% to
Jiambalvo Managerial Accounting6-6
department 2. Department 1 would prefer to be allocated cost based on square
footage and department 2 would prefer direct labor hours as the base.
(2) An allocation base that results in a cause and effect allocation is preferred.
If maintenance costs are mostly related to building maintenance, then square
footage is more likely to result in a cause and effect allocation. However, if
maintenance costs are mostly made up of machine maintenance, then machine
hours might be a better allocation base.
E8. P1 has 150/375 = 40% of production department employees.
P2 has 225/375 = 60% of production department employees.

E9. a. The manufacturing overhead allocation includes $52 of fixed cost which
will not increase if the special order is accepted (i.e., it is not an
incremental cost). The incremental revenue and incremental costs
associated with the order suggests that the company will be better off by
$45,000 if the order is accepted.
Incremental revenue (1,000 × $175) $175,000
Material (1,000 × $80) 80,000
Labor (1,000 × $40) 40,000
Variable overhead (($1,000 × $10) 10,000 130,000
Incremental profit $ 45,000
b. Managers who focus on reported cost may (incorrectly) treat the $52 of
fixed cost as an incremental cost. In this case they will (incorrectly)
conclude that the order should not be accepted because the total cost
($182) is greater than the offer ($175).
Chapter 6 Cost Allocation and Activity-Based Costing 6-7
E10. a. The reason that allocated general and administrative costs are higher for
the Services Department is that revenue in the Sales Department has
decreased. Since general and administrative costs are allocated based on
actual revenues, changes in one department’s revenue affects another
department’s allocation of overhead costs (since it has a higher
proportion of total revenue).
b. If accounting department costs are affected by Rex Kerr’s decisions, then
he should be held responsible for those costs. However, it appears that
his department is being allocated costs over which he has no control.
Allocating cost beyond Kerr’s control may cause him to feel that he has
been treated unfairly, especially if his performance is based on the
service department’s profits.
E11. a. The manager of Keller Auto Insurance will perceive that allocated service
department costs are variable cost (when auto insurance revenue
increases, the allocated costs increase).
b. In performing incremental analysis, the president of Keller Auto
Insurance will tend to overestimate incremental costs because he or she
will treat allocated costs as incremental costs (when some of the costs
are, in all likelihood, fixed).
Jiambalvo Managerial Accounting6-8
E12.a. The use of a single cost pool causes A1 to be undercosted and B1 to be
overcosted. With a single cost pool, both products receive the same
allocation of cost per labor hour. However, A1 uses relatively more time
in P1 where overhead costs are high while B1 uses relatively more time
in P2 where overhead costs are low.
The one-cost pool overhead rate is:
$3,000,000 ÷ 400,000 DLH = $7.50 /DLH
Each product requires 5 direct labor hours in total. Therefore, each will be
allocated $37.50 in overhead costs ($7.50 × 5)
Now let’s calculate the amount of overhead allocated to each product if Mott
used a separate overhead cost pool for each production department.
P1’s overhead rate will be $2,000,000 ÷ 100,000 DLH = $20.00 per direct
P2’s overhead rate will be $1,000,000 ÷ 300,000 DLH = $3.33 per direct
Overhead allocated to each unit of A1 will be:
(2 labor hours × $20) + (3 labor hours × $3.33) $49.99
Overhead allocated to each unit of B1 will be:
(1 labor hour × $20) + (4 labor hours × $3.33) $33.32
Note that the overhead allocated to B1 is lower with two cost pools while the
allocation to A1 is higher.
E13. a. If the costs of the design department are fixed and the department is able
to complete jobs on a timely basis, then the opportunity cost of using the
department is approximately zero and equal to the allocation (which is
b. Subsidiaries often have to go outside for design work because of time
delays. Thus, there is an opportunity cost associated with use that is
greater than the allocation (which is zero).
c. The allocation of $50 per hour must be less than the opportunity cost
(subsidiaries are willing to pay $70 per hour to avoid delays). Thus, they
must have a benefit that exceeds $70.
Chapter 6 Cost Allocation and Activity-Based Costing 6-9
d. The opportunity cost of using design services may be less than $50 since
no one is being turned away or delayed. Thus, there does not appear to be
a benefit foregone because of use.
E14. COST POOL COST DRIVER

E15. Cost per setup = $1,500,000 ÷ 1,000 = $1,500
Cost of setups related to EP150 = 2 × $1,500 = $3,000
Setup cost per unit of EP150 = $3,000 ÷ 750 = $4
E16. If the cost to process an order is much higher at one plant than at the other
and the orders are similar, then there is a good chance that the costs are out
of control at the higher cost location and a manager should investigate the
situation. Conceivably, the company can adopt “best practices” from the
low cost plant.
E17. a. The cost of filling orders at PorcheParts.com is:
($250,000 + $300,000) ÷ 100,000 = $5.50 per order.
The cost of filling orders at the auto supply chain is only $4 per hour.
While this is lower, it may be that that, due to its size, the auto supply
chain has a “state of the art” warehouse. It may be unrealistic for
PorcheParts.com, which is relatively small, to compare itself to such a
b. Possibly, order “pickers” can take multiple order sheets out to the
warehouse when individual orders are small. This will save considerable
time going back and forth to the warehouse and may lead to lower costs
if the company is willing to fire or reassign one or more of the five
workers who pick parts.

b. Assuming the controller’s assumptions are correct (that benefits and
telecommunications costs are driven by headcount while rent is driven by
space occupied and general and administrative costs are driven by relative
sales), then the multiple cost pools provide better information on the resources
consumed and the profitability of the two divisions.

P2. a. The opportunity cost of producing a Model 350 motor is simply the
incremental cost of production (given that Binder has excess capacity and
sales to Dacon will not affect sales to other customers).
Direct material $20
Direct labor 10
Variable overhead ($.80 × direct labor)* 8
* Variable overhead rate is equal to $4,000,000 of variable overhead ÷
$5,000,000 of direct labor.
b. Since 60 percent of the overhead is fixed ($12 per motor), the incremental cost
to produce the motors is $38 per motor ($20 + 10 + 8). Any bid greater than
$38 (that’s accepted) will generate incremental profit. If Binder can get the
order with a bid of $48, the company should bid this amount. It will generate
incremental profit of $50,000 [($48 - $38) × 5,000 motors].
c. The opportunity cost related to overhead, in this case, is simply the variable
overhead amount. An allocation based on the opportunity cost idea, helps

b. The price charged for the civilian version of the Model KV10 does not
depend on allocated costs. However, the military version is sold for “cost”
plus 10 percent of cost. Therefore, the company has an incentive to make
cost appear higher rather than lower. This can be accomplished by
allocating overhead cost using direct labor cost as the allocation base. This
base results in a higher cost ($12,400) compared to an allocation based on
machine hours which results in a cost of only $11,400.
c. Many, if not most, managers believe that “it is well known that allocation
is somewhat arbitrary and the government is not at all surprised that
companies pick allocation bases to maximize their profit.” Since no one is
being “fooled,” the behavior is not illegal, and the “right” allocation isn’t
obvious, picking an allocation base to maximize profit does not appear to

b. The best cause-and-effect relation is probably between maintenance costs
and air miles flown (the most suspect relation is between ticketing and air
miles flown—more miles do not lead to higher ticketing costs). Given that
international passengers have more baggage and have more transfers than
domestic flyers, the relation between baggage handling costs and air miles
flown is probably stronger than the relation between air miles and ticketing
but weaker than the relation between air miles and maintenance.
A better allocation base for ticketing might be number of tickets issued. A
better allocation base for baggage handling might be number of bags

The current overhead cost for an 8 labor-hour job is 60% more than the prior
b. Small jobs in the current year appear to be less profitable compared to the
prior year. This is because they are allocated overhead costs as if they
required use of the new equipment. Therefore, small jobs will be
overcosted. In all likelihood, the jobs do not really cost more than they did
in the prior year. One way to avoid miscosting of small (labor-intensive)
jobs would be to develop a separate overhead allocation rate for jobs that
are labor intensive and do not make use of the new equipment.

d. The traditional allocation method used by Summit is essentially a volume-
based method. In this problem, each unit of the competition kayak used the
same amount of direct labor as a recreation kayak, but required much more of
some overhead resources. For example, total competition kayaks accounted
for 10 percent of volume and required 10 percent of direct labor but needed
66.7 percent of set up and drafting resources. Using a single traditional
allocation base assumes that each product uses all overhead resources in the
same proportion that the allocation base is used. Except for supervision,
competition kayaks use more than 10 percent of overhead resources. Better
information will be provided by an ABC system. With an ABC system, cost
pools will be formed for key activities and overhead drivers (allocation bases)
need not be based on production volume.

Overhead assigned to each unit of Remote Mouse
($1.91 × $6.00 direct labor cost) $11.46
ABC assigns $6.44 more overhead to each unit of Remote Mouse than is
assigned using a traditional production volume base. Remote Mouse
production uses only 1.2 percent of direct labor dollars, but requires 10
percent of materials ordering, 15 percent of materials inspection, and 10
percent of quality control resources. Remote Mouse production uses a
relatively a small amount of direct labor dollars and is therefore undercosted a
traditional approach to allocation.

P12. With 6,000 employees and turnover of 15%, 900 people leave the company
and 900 are added to take their place each year (.15 x 6,000). With this in
mind, having 6 employees to handle new employee training appears
excessive. Suppose each new employee requires a half day of training. That
implies 450 training days. Assume that each trainer works 5 days per week
for 48 weeks per year. Then, each trainer covers 240 training days. Thus,
only 2 trainers are needed (450 ÷ 240 = 1.875). Reducing trainers by 4 would
save $20,000 in salary each month.
Now, consider operations. It’s not clear that 5 clerks are needed. Suppose
paperwork related to resignations and new hires is 2 hours per person. This
implies a need for 3,600 hours (2 hours x 1,800 resignations or hires).
Assuming each clerk works 8 hours per day, with a 5 day work week for 48
weeks, a clerk has 1,920 hours. Again, it appears that only 2 clerks are
needed (3,600 ÷ 1,920 = 1.875). A reduction of 3 clerks would save $7,500
Based on the above analysis, which admittedly required some “ballpark”
assumptions, the low hanging fruit is in operations and training.
Note that the total savings is estimated to be $27,500 per month or $330,000
per year. Assuming the ABM study reduced waste for 3 years, the company
would save approximately $1,000,000. If similar savings could be found in
other departments, ABM would create substantial shareholder value.
