Q4: Budget Variances
• Managers compare actual results to
budgeted results in order to
• Monitor operations, and
• Motivate appropriate performance.
• Differences between budgeted and
actual results are called budget
variances.
• Variances are stated in absolute value
terms, and labeled as Favorable or
Unfavorable.

Slide # 19
Q4: Budget Variances
• Reasons for budget variances are
investigated.
• The investigation may find:
• Inefficiencies in actual operations that can
be corrected.
• Efficiencies in actual operations that can be
replicated in other areas of the
organization.
• Uncontrollable outside factors that require
changes to the budgeting process.

Q3: Static Budgets
• A budget prepared for a single level of
sales volume is called a static budget.
• Static budgets are prepared at the
beginning of the year.
• Differences between actual results and
the static budget are called static budget
variances.

Slide # 21
Q3: Flexible Budgets
• A budget prepared for a multiple levels of sales
volume is called a flexible budget.
• Flexible budgets are prepared at the beginning
of the year for planning purposes and at the end
of the year for performance evaluation.
• Flexible budgets are also used for sensitivity
analysis and to manage risk due to uncertainty.
• Differences between actual results and the
flexible budget are called flexible budget
variances.

Q3, Q4: Performance Evaluation
• A static budget variance includes effects from
output volume.
• A flexible budget variance removes these
output volume effects.
• Other adjustments to the year-end flexible
budget may be made for a fair performance
evaluation, such as
• Input price changes outside the control of the
manager under evaluation
• Fixed cost increases outside the control of the
manager under evaluation

Slide # 26
Q5: Behavior Tensions in Budgeting
• Budgets used to evaluate performance and
compensation can create behavioral tension
• Participative budgeting – when managers who are
responsible for the budgets prepare the budget
forecasts
– Can result in budgetary slack – when managers set
targets so low that goals can be met easily (and bonuses
achieved)
• Budget ratcheting – when top managers set targets
– If targets unachievable, this can result in employees
having little motivation to meet targets
• Organizations must watch for budget manipulation

Slide # 27
Q6: Other Budgeting Approaches
• Zero based budgets are prepared without using
past information as justification.
• Rolling budgets are prepared frequently for
overlapping time periods and actual results may be
used to update the budget for the next period.
• Kaizen budgets plan cost reductions over time.
• Activity based budgets use more cost pools and
cost drivers.
• GPK and RCA budgets identify fixed and variable
cost functions at the resource center level.
• Beyond budgeting uses external benchmarks to
evaluate managers’ performance

Q1: Joint Processes and Costs
• A process that yields one or more products is
called a joint process.
• The products are called joint products.
• The costs of the process are called joint costs.
• The split-off point is the stage in the joint process
where the separate products become
identifiable.
• Joints costs are incurred prior to the split-off point.
• Costs incurred past split-off are separable costs.
• Joint products that have minimal sales value
compared to the main product are called byproducts.

Q2: Methods of Allocating Joint Costs
• Physical output methods
• Can be used only when joint products are
measured the same way (e.g. pounds or feet).
• Market-based methods
• Sales value at split-off method
• Often used when all products sold at split-off.
• Net realizable value (NRV) method
• NRV = Final selling price – Separable costs.
• Constant gross margin (GM) NRV method
• The two NRV methods can be used when
some products are processed past split-off.

Q2: Constant GM NRV Method
• Under the constant GM NRV method, all products
are allocated joint costs to achieve the same gross
margin ratio (GM%).
• First compute overall gross margin and GM%:
GM = Revenue – Joint costs – Separable costs
GM% = GM/Sales
• Then compute the GM for each product:
GM = Final sales value x GM%
• All products end up with the same gross margin ratio;
for each product solve for allocated joint costs:
Final sales value – joint costs – separable costs = GM

Q3: Choosing a Joint Cost Allocation Method
• Allocated joint costs should not be used in
decision making.
• Still, avoid a method that shows one product
to be unprofitable.
• Under the physical volume method, the
product with the greatest relative physical
volume is allocated the most joint costs,
regardless of product’s sales value.
• Both of the NRV methods allocate joint
costs based on the products’ “ability to
bear the cost”.

Q4: Sell or Process Further Decisions
• Companies often can choose to sell a product
at the split-off point or to process it further.
• Compare the incremental revenue of
processing further to the product’s separable
costs.
• Incremental revenue of processing further
= Final sales value – Sales value at split-off
• Process further only when the incremental
revenue exceeds the separable costs.

Q5: Accounting for By-Products
• When by-products have no sales value, there
is no reason to account for them.
• Otherwise, there are two accounting methods
available:
• Recognize by-product value at time of
production
• Recognize by-product value at time of
by-product sale

Q5: Recognize By-Product Value
at Time of Production
• This method is also known as the offset approach or
the NRV approach.
• Joint cost of the main products is reduced by the
NRV of the by-products, even if by-products are not
yet sold.
• NRV of the by-products is kept in ending
inventory until sold.
• At sale of by-product, ending inventory is
reduced; there is no gain/loss on sale.
• This method allows managers to control by-products.

• Joint cost information is required for
financial statement & tax return preparation
when production does not equal sales
(inventory and cost of goods sold).
• Allocated joint costs are irrelevant for most
decisions, especially regarding individual
products
• Joint cost information should not be

Q1: Activity-Based Costing (ABC)
• ABC is a method of cost system refinement.
• Indirect costs are divided into “sub-pools” of
costs of activities.
• Activity costs are then allocated to the final cost
objects using a cost allocation base (more
commonly called cost drivers in ABC).
• Activities are measurable, making it more likely
that cost drivers can be found so that a final cost
object will absorb indirect costs in proportion to
its use of the activity.

Q5: What are GPK and RCA?
• Costing approaches similar to ABC because they
involve multiple pools and multiple drivers
• GPK can be described as marginal planning and
cost accounting
– Each cost is traced to a cost center (smaller than a
department) which performs a single repetitive activity,
and is the responsibility of one manager)
– Output measures tracks the volume of resource use
– Costs are segregated into proportional (change with
volume in resource use) and fixed
– Practical capacity is used for estimated allocation rate
volumes

Slide # 22
Q5: Capacity Definitions
• Theoretical capacity – maximum assuming
continuous, uninterrupted operations 365 days/year
• Practical capacity – typical operating conditions
• Budgeted capacity – expected volume for the
upcoming time period
• Idle/excess capacity – difference between activity
capacity used and one of the above measures of
capacity

Slide # 23
Q5: What are GPK and RCA?
• Resource Consumption Accounting (RCA)
• Builds on GPK and ABC principles
• Each cost is assigned to a resource cost pool
– Labor and machinery are often placed in different cost
pools since they are different types of resources
– RCA involves a significantly larger number of cost pools
than traditional accounting
– Like GPK, segregates proportional and fixed costs
– Utilizes theoretical rather than practical capacity for
allocating fixed costs
• More likely to focus manager attention on reducing idle and nonproductive resource time

Slide # 24
Q5: Benefits/Drawbacks to GPK/RCA
• Benefits
– Generates multi-level internal income statements useful
for short terms decisions because it focuses on marginal
cost
– Increases cause & effect awareness among managers
– Categorizes costs (and generates profit margin) at the
product, product group, division, and company level
– Avoids arbitrary allocations of fixed costs

Q1: Support versus Operating Departments
• The operating departments of an organization
produce products or services that generate
revenue.
• The support departments of an organization
produce products or provide services to the
operating and other support departments.
• The support department costs are common
costs that are shared between two or more
other departments.

Q2: Process for Allocating Support
Department Costs
1. Clarify allocation purpose
•
if the purpose is to motivate the use of the services
of a newly formed department, perhaps no costs
should be allocated
•
if the purpose is to discourage operating department
managers from over-use of the services of support
departments, then a rate per unit of service might be
large and not based on actual costs
•
if the purpose is to determine the full cost of products
or services for long-term pricing decisions, then all
support costs should be allocated

Q4: The Step-Down Method of Allocating
Support Department Costs
• The step-down method allocates some (but not all)
support department costs to other support
departments.
• The first support department’s costs are allocated
to all operating and support departments that use
its services.
• Each subsequent support department’s costs are
allocated to all operating and support departments
that use its services, except any support
department whose costs were already allocated.
• Allocation order must be determined.

Q4: The Step-Down Method Example
Given the information for Philco, use the step-down method to allocate
support department costs. Allocate the costs of the support department that
provides the largest percentage of its services to the other support
department first.
First determine
allocation order:
Accounting provided 4/(4+22+16) = 4/42
= 9.5% of its services to Info Systems.
Information Systems provided 4/(4+3+3) = 4/10 = 40% of its
services to Accounting, so Information Systems goes first.

Q5: The Reciprocal Method of Allocating
Support Department Costs
• The reciprocal method allocates all support
department costs to other support
departments.
• The first step is to compute the total costs of
each support department when its usage of
other support department services is taken
into consideration.
• Support department costs are then allocated
to all other operating and support
departments that consume its services.

Slide # 21
Q5: The Reciprocal Method Example
Given the information for Philco, use the reciprocal method to allocate
support department costs.
First determine total costs for each support department by writing an equation for its
costs (use A and IS as abbreviations).
A = $48,000 + [4/(4+3+3)] x IS; IS = $72,000 + [4/(4+22+16)] x A
Then solve: A = $48,000 + (4/10) x [$72,000 + (4/42) x A]
A = $48,000 + $28,800 + (16/420) x A]
(404/420) x A = $76,800
A = $76,800 x (420/404) = $79,842
IS = $72,000 + (4/42) x $79,842 = $79,604

• In single-rate allocation, each cost pool
includes fixed and variable costs.
• In dual-rate allocation, fixed and variable
costs are in separate cost pools.
• Both methods can be employed with the

Q7: Decision Making with Support Costs
• Support costs need to be considered when
evaluating decisions such as make/buy, keep/drop,
special order, and constrained resource
• Necessary to isolate relevant support costs
– This may not be the same as the allocated support costs
– For example, outsourcing an operating department may
not result in a reduction in support department costs

Q7: Establishing Transfer Prices for
Support Departments
• Transfer prices should be set to motivate efficient
use of the support department resources
– If transfer price is set too high, user departments may
outsource the service
– If transfer price is set too low, user departments may
utilize the support department inefficiently
• The best transfer pricing approach is the
Opportunity Cost approach
– Each department is charged an amount that reflects the
value of any opportunities forgone by not using the
service for its next best alternative use.
– This is often difficult in practice so most companies use a
cost based or market based transfer pricing policy

Q7: Estimated versus Actual
Support Costs and Rates
• Actual rates and consumption may be
required for some types of government
contracts.
• Most federal grants to educational institutions
allow the use of estimates.
• Using an actual rate means that support
service users are affected by
• inefficiencies of support department managers
• changes in the consumption of support services by other
users

Q7: Other Common Cost Allocation Methods
• Other cost allocation purposes may require the
allocation to
• be perceived as “fair”
• be based on the user’s “ability to bear” the cost
• Under the stand-alone method, a common cost is
allocated based on information about the users’
consumption of the cost.
• Under the incremental cost allocation method, a
“primary user” is allocated the bulk of the common
cost and the secondary user is allocated only the
increment in cost that it caused.

Q7: Stand-Alone versus Incremental Cost
Allocation Methods Example
Leslie has a job interview with Big Co. next month in New York City. Her
plane ticket cost $300, and she will need to spend $125/night for 2 nights in
a hotel. She estimates that she will spend $50 in cab fares and $50 for
food. Big Co. has promised to reimburse her actual costs. After this trip
was arranged, Small Co., also located in New York City, called her for an
interview. If she interviews with Small Co. while she’s there, she will spend
an additional $125 for another night at a hotel, and another estimated $40
in cab fares and food. Think of at least two ways to allocate Leslie’s travel
costs using the stand-alone method. Discuss the merits of each.
1. Compute the total cost of the trip and divide it by 2, since
there are 2 interviews.
2. Compute the total cost of the trip and allocate 2/3 of it to
Big Co. and 1/3 to Small Co. since she is spending 2 of
the 3 nights in NYC for the Big Co. interview.

Q7: Stand-Alone versus Incremental Cost
Allocation Methods Example
Perform the calculations for your two versions of the cost allocation under
the stand-alone method. Then allocate the travel costs using the
incremental cost allocation method. Which is more appropriate? Why?
Estimated total costs:
Plane ticket
Hotel
Cab fares & food
Total
If shared equally, then this is
$300 $407.50 for each company; if
375 Big Co. is allocated 2/3 of the
140 cost then $543.33 is allocated
$815
to Big Co. and $271.67 is
allocated to Small Co.
Under the incremental cost allocation method, Big Co. is most
likely to be considered the primary user. Since Leslie’s budgeted
travel costs were $300 + $250 + $50 + $50 = $650 before she
was offered the Small Co. interview, Big Co. is allocated $650
and Small Co. is allocated $815 – $650 = $165.

Q7: Fixed Price versus Cost-Based Contracts
• Under fixed price contracts, vendors provide
products or services for a specified price.
• Under cost-based contracts, the price is
computed based on the actual cost of the
products or services.
• may be necessary for research & new product development
• vendors are not motivated to control costs
• vendors may be motivated to inappropriately allocate
common costs

• A static budget variance includes effects from
output volume.
• A flexible budget variance removes these
output volume effects.
• Other adjustments to the year-end flexible
budget may be made for a fair performance
evaluation, such as
• Input price changes outside the control of the
manager under evaluation
• Fixed cost increases outside the control of the

Q5: Behavior Tensions in Budgeting
• Budgets used to evaluate performance and
compensation can create behavioral tension
• Participative budgeting – when managers who are
responsible for the budgets prepare the budget
forecasts
– Can result in budgetary slack – when managers set
targets so low that goals can be met easily (and bonuses
achieved)
• Budget ratcheting – when top managers set targets
– If targets unachievable, this can result in employees
having little motivation to meet targets
• Organizations must watch for budget manipulation

Q6: Other Budgeting Approaches
• Zero based budgets are prepared without using
past information as justification.
• Rolling budgets are prepared frequently for
overlapping time periods and actual results may be
used to update the budget for the next period.
• Kaizen budgets plan cost reductions over time.
• Activity based budgets use more cost pools and
cost drivers.
• GPK and RCA budgets identify fixed and variable
cost functions at the resource center level.
• Beyond budgeting uses external benchmarks to
evaluate managers’ performance

• A process that yields one or more products is
called a joint process.
• The products are called joint products.
• The costs of the process are called joint costs.
• The split-off point is the stage in the joint process
where the separate products become
identifiable.
• Joints costs are incurred prior to the split-off point.
• Costs incurred past split-off are separable costs.
• Joint products that have minimal sales value
compared to the main product are called byproducts.

Q2: Methods of Allocating Joint Costs
• Physical output methods
• Can be used only when joint products are
measured the same way (e.g. pounds or feet).
• Market-based methods
• Sales value at split-off method
• Often used when all products sold at split-off.
• Net realizable value (NRV) method
• NRV = Final selling price – Separable costs.
• Constant gross margin (GM) NRV method
• The two NRV methods can be used when
some products are processed past split-off.

Q2: Constant GM NRV Method
• Under the constant GM NRV method, all products
are allocated joint costs to achieve the same gross
margin ratio (GM%).
• First compute overall gross margin and GM%:
GM = Revenue – Joint costs – Separable costs
GM% = GM/Sales
• Then compute the GM for each product:
GM = Final sales value x GM%
• All products end up with the same gross margin ratio;
for each product solve for allocated joint costs:
Final sales value – joint costs – separable costs = GM

Q3: Choosing a Joint Cost Allocation Method
• Allocated joint costs should not be used in
decision making.
• Still, avoid a method that shows one product
to be unprofitable.
• Under the physical volume method, the
product with the greatest relative physical
volume is allocated the most joint costs,
regardless of product’s sales value.
• Both of the NRV methods allocate joint
costs based on the products’ “ability to
bear the cost”.

Q4: Sell or Process Further Decisions
• Companies often can choose to sell a product
at the split-off point or to process it further.
• Compare the incremental revenue of
processing further to the product’s separable
costs.
• Incremental revenue of processing further
= Final sales value – Sales value at split-off
• Process further only when the incremental
revenue exceeds the separable costs.

Q5: Accounting for By-Products
• When by-products have no sales value, there
is no reason to account for them.
• Otherwise, there are two accounting methods
available:
• Recognize by-product value at time of
production
• Recognize by-product value at time of
by-product sale

Slide # 17
Q5: Recognize By-Product Value
at Time of Production
• This method is also known as the offset approach or
the NRV approach.
• Joint cost of the main products is reduced by the
NRV of the by-products, even if by-products are not
yet sold.
• NRV of the by-products is kept in ending
inventory until sold.
• At sale of by-product, ending inventory is
reduced; there is no gain/loss on sale.
• This method allows managers to control by-products.

Approach or the RV Approach.
• Joint cost of the main products is not reduced by
the NRV of the by-products, regardless if byproducts are sold.
• NRV of the by-products is not kept in ending
inventory.
• At sale of by-product, either Other Income is
recorded or Cost of Goods Sold is reduced.

Q7: Decision Making & Joint Cost
• Joint cost information is required for
financial statement & tax return preparation
when production does not equal sales
(inventory and cost of goods sold).
• Allocated joint costs are irrelevant for most
decisions, especially regarding individual
products
• Joint cost information should not be
used to make product mix decisions.

Q1: Activity-Based Costing (ABC)
• ABC is a method of cost system refinement.
• Indirect costs are divided into “sub-pools” of
costs of activities.
• Activity costs are then allocated to the final cost
objects using a cost allocation base (more
commonly called cost drivers in ABC).
• Activities are measurable, making it more likely
that cost drivers can be found so that a final cost
object will absorb indirect costs in proportion to
its use of the activity.

Alphabet Co. makes products A & B. Product A is a low-volume
specialty item and B is a high-volume item. Estimated factory- wide
overhead is $800,000, and the number of DL hours for the year is
estimated to be 50,000 hours. DL costs are $10/hour. Each product
uses 2 DL hours. Compute the traditional cost of each product if
Products A & B use $25 and $10 in direct materials, respectively.
First, compute the estimated overhead rate:
Estimated overhead rate = $800,000/50,000 hours = $16/hour.

Traditional costing
assigned $77 to a unit of
Product A and $62 to a
unit of Product B.
•
The only difference between the two costing systems is that
Product A is assigned more overhead costs under ABC.
•
The additional overhead assigned to Product A reflects Product
A’s consumption of resources.

Q4: Activity-Based Management (ABM)
• ABM is the process of using ABC information to
evaluate opportunities for improvements in an
organization.
• Examples include managing & monitoring
• customer profitability
• product and process design
• environmental costs
• quality
• constrained resources

Q4: ABM & Customer Profitability
• Activities can be defined so that different costs of
servicing customers are accumulated.
• Examples include
• analyzing the types of bank transactions used
by various categories of customers
• comparing the costs of servicing insurance
contracts sold to married versus single
individuals
• comparing the costs of different distribution
channels

Q4: ABM & Product/Process Improvements
• Activities can be defined so that the costs of stages
of production or of a business process are
accumulated.
• Examples include
• determining the costs of non-value-added
activities so the most costly can be reduced or
eliminated
• changing the steps in the accounts payable
function to reduce the number of personnel
• determining the most costly stages of product
development so that the time to market is

Q5: What are GPK and RCA?
• Costing approaches similar to ABC because they
involve multiple pools and multiple drivers
• GPK can be described as marginal planning and
cost accounting
– Each cost is traced to a cost center (smaller than a
department) which performs a single repetitive activity,
and is the responsibility of one manager)
– Output measures tracks the volume of resource use
– Costs are segregated into proportional (change with
volume in resource use) and fixed
– Practical capacity is used for estimated allocation rate
volumes

Q5: Capacity Definitions
• Theoretical capacity – maximum assuming
continuous, uninterrupted operations 365 days/year
• Practical capacity – typical operating conditions
• Budgeted capacity – expected volume for the
upcoming time period
• Idle/excess capacity – difference between activity
capacity used and one of the above measures of
capacity

Slide # 23
Q5: What are GPK and RCA?
• Resource Consumption Accounting (RCA)
• Builds on GPK and ABC principles
• Each cost is assigned to a resource cost pool
– Labor and machinery are often placed in different cost
pools since they are different types of resources
– RCA involves a significantly larger number of cost pools
than traditional accounting
– Like GPK, segregates proportional and fixed costs
– Utilizes theoretical rather than practical capacity for
allocating fixed costs
• More likely to focus manager attention on reducing idle and nonproductive resource time

Q5: Benefits/Drawbacks to GPK/RCA
• Benefits
– Generates multi-level internal income statements useful
for short terms decisions because it focuses on marginal
cost
– Increases cause & effect awareness among managers
– Categorizes costs (and generates profit margin) at the
product, product group, division, and company level
– Avoids arbitrary allocations of fixed costs
• Drawbacks
– Can be costly to implement
– Can result in a large number of variances to analyze

Q1: Support versus Operating Departments
• The operating departments of an organization
produce products or services that generate
revenue.
• The support departments of an organization
produce products or provide services to the
operating and other support departments.
• The support department costs are common
costs that are shared between two or more
other departments.

Q2: Process for Allocating Support
Department Costs
1. Clarify allocation purpose
•
if the purpose is to motivate the use of the services
of a newly formed department, perhaps no costs
should be allocated
•
if the purpose is to discourage operating department
managers from over-use of the services of support
departments, then a rate per unit of service might be
large and not based on actual costs
•
if the purpose is to determine the full cost of products
or services for long-term pricing decisions, then all
support costs should be allocated

Q4: The Step-Down Method of Allocating
Support Department Costs
• The step-down method allocates some (but not all)
support department costs to other support
departments.
• The first support department’s costs are allocated
to all operating and support departments that use
its services.
• Each subsequent support department’s costs are
allocated to all operating and support departments
that use its services, except any support
department whose costs were already allocated.
• Allocation order must be determined.

Q4: The Step-Down Method Example
Given the information for Philco, use the step-down method to allocate
support department costs. Allocate the costs of the support department that
provides the largest percentage of its services to the other support
department first.
First determine
allocation order:
Accounting provided 4/(4+22+16) = 4/42
= 9.5% of its services to Info Systems.
Information Systems provided 4/(4+3+3) = 4/10 = 40% of its
services to Accounting, so Information Systems goes first.

Q5: The Reciprocal Method of Allocating
Support Department Costs
• The reciprocal method allocates all support
department costs to other support
departments.
• The first step is to compute the total costs of
each support department when its usage of
other support department services is taken
into consideration.
• Support department costs are then allocated
to all other operating and support
departments that consume its services.

Slide # 21
Q5: The Reciprocal Method Example
Given the information for Philco, use the reciprocal method to allocate
support department costs.
First determine total costs for each support department by writing an equation for its
costs (use A and IS as abbreviations).
A = $48,000 + [4/(4+3+3)] x IS; IS = $72,000 + [4/(4+22+16)] x A
Then solve: A = $48,000 + (4/10) x [$72,000 + (4/42) x A]
A = $48,000 + $28,800 + (16/420) x A]
(404/420) x A = $76,800
A = $76,800 x (420/404) = $79,842
IS = $72,000 + (4/42) x $79,842 = $79,604

Q6: Single- versus Dual-Rate Allocation
• In single-rate allocation, each cost pool
includes fixed and variable costs.
• In dual-rate allocation, fixed and variable
costs are in separate cost pools.
• Both methods can be employed with the
direct, step-down, or reciprocal methods.
• The prior three examples used the singlerate allocation method.

Q6: Single- versus Dual-Rate Example
Philco has decided to use the direct method and allocate variable
Accounting costs based on the number of transactions and fixed
Accounting costs based on the number of employees. The Info Systems
variable costs will be allocated based on the number of service requests
and fixed costs will be allocated based on the number of computers. The
required information is presented below.

Q7: Decision Making with Support Costs
• Support costs need to be considered when
evaluating decisions such as make/buy, keep/drop,
special order, and constrained resource
• Necessary to isolate relevant support costs
– This may not be the same as the allocated support costs
– For example, outsourcing an operating department may
not result in a reduction in support department costs

Q7: Establishing Transfer Prices for
Support Departments
• Transfer prices should be set to motivate efficient
use of the support department resources
– If transfer price is set too high, user departments may
outsource the service
– If transfer price is set too low, user departments may
utilize the support department inefficiently
• The best transfer pricing approach is the
Opportunity Cost approach
– Each department is charged an amount that reflects the
value of any opportunities forgone by not using the
service for its next best alternative use.
– This is often difficult in practice so most companies use a
cost based or market based transfer pricing policy

Q7: Estimated versus Actual
Support Costs and Rates
A department’s allocation
of support department costs
=
the allocation
rate
x
the department’s
consumption
of the allocation base
Either of these could be estimated or actual.

Q7: Estimated versus Actual
Support Costs and Rates
the allocation
rate
x
the department’s
consumption
of the allocation base
Using actual rates and actual consumption provides the
best measure of the cost of support services; it is the
most accurate but the least timely.
The purpose of the cost allocation will determine
whether actual or estimated rates, and actual or
estimated consumption, should be used.

Q7: Estimated versus Actual
Support Costs and Rates
• Actual rates and consumption may be
required for some types of government
contracts.
• Most federal grants to educational institutions
allow the use of estimates.
• Using an actual rate means that support
service users are affected by
• inefficiencies of support department managers
• changes in the consumption of support services by other
users

Q7: Other Common Cost Allocation Methods
• Other cost allocation purposes may require the
allocation to
• be perceived as “fair”
• be based on the user’s “ability to bear” the cost
• Under the stand-alone method, a common cost is
allocated based on information about the users’
consumption of the cost.
• Under the incremental cost allocation method, a
“primary user” is allocated the bulk of the common
cost and the secondary user is allocated only the
increment in cost that it caused.

Q7: Stand-Alone versus Incremental Cost
Allocation Methods Example
Leslie has a job interview with Big Co. next month in New York City. Her
plane ticket cost $300, and she will need to spend $125/night for 2 nights in
a hotel. She estimates that she will spend $50 in cab fares and $50 for
food. Big Co. has promised to reimburse her actual costs. After this trip
was arranged, Small Co., also located in New York City, called her for an
interview. If she interviews with Small Co. while she’s there, she will spend
an additional $125 for another night at a hotel, and another estimated $40
in cab fares and food. Think of at least two ways to allocate Leslie’s travel
costs using the stand-alone method. Discuss the merits of each.
1. Compute the total cost of the trip and divide it by 2, since
there are 2 interviews.
2. Compute the total cost of the trip and allocate 2/3 of it to
Big Co. and 1/3 to Small Co. since she is spending 2 of
the 3 nights in NYC for the Big Co. interview.

Q7: Stand-Alone versus Incremental Cost
Allocation Methods Example
Perform the calculations for your two versions of the cost allocation under
the stand-alone method. Then allocate the travel costs using the
incremental cost allocation method. Which is more appropriate? Why?
Estimated total costs:
Plane ticket
Hotel
Cab fares & food
Total
If shared equally, then this is
$300 $407.50 for each company; if
375 Big Co. is allocated 2/3 of the
140 cost then $543.33 is allocated
$815
to Big Co. and $271.67 is
allocated to Small Co.
Under the incremental cost allocation method, Big Co. is most
likely to be considered the primary user. Since Leslie’s budgeted
travel costs were $300 + $250 + $50 + $50 = $650 before she
was offered the Small Co. interview, Big Co. is allocated $650
and Small Co. is allocated $815 – $650 = $165.

Q7: Fixed Price versus Cost-Based Contracts
• Under fixed price contracts, vendors provide
products or services for a specified price.
• Under cost-based contracts, the price is
computed based on the actual cost of the
products or services.
• may be necessary for research & new product development
• vendors are not motivated to control costs
• vendors may be motivated to inappropriately allocate
common costs

Appendix 8A: Excel Solver
and the Reciprocal Method
• Solving the simultaneous equations required for
the reciprocal method can be tedious when
there are 3 or more support departments.
• Excel Solver can be used to solve these
equations.
• Refer to Appendix 4A for help with using
Excel Solver.

Appendix 8A: Excel Solver
and the Reciprocal Method
• Set up a “change cell” for each support
department’s total costs.
• The target function is the sum of the change
cells.
• The simultaneous equations are entered as
constraints; one constraint per equation.
