Title: Cost Management MSCM8615
1Cost ManagementMSCM8615
2Definition of cost
- A monetary measure of the resources given up to
acquire a good or service
3Why Incur Costs?
- If the organization believes that incurring a
cost provides a future benefit that exceeds the
cost, then it would be a worthwhile use of the
companys resources
4The Value of Cost Info
- Cost information assists management in the
decision making, planning, directing, and
controlling functions - Examples of the use of cost info
- Pricing services or activities
- deciding among program alternatives
- how much of a raise to give employees
- income measurement and asset valuation
- etc.
5Cost Concepts
- Cost object the entity (product, service,
department, process, decision, etc.) which we
want to know the cost of - Cost accumulation gathering cost data in an
organized manner - Cost allocation assigning costs to a cost object
based on a cost driver - Cost driver a characteristic of an event or
activity that causes costs to be incurred
6Direct vs. Indirect Costs
- Direct cost a cost that can be traced in an
economically feasible manner to a cost object - Indirect cost a cost that cannot be traced in an
economically feasible manner to a cost object - Note that the choice of the cost object
determines whether a particular cost is
considered direct or indirect - Example
7Example of Direct vs. Indirect Costs
8Cost Behavior
- Fixed costs those costs that, in total, do not
change when the level of activity changes - Variable costs those costs that, in total,
change in direct proportion to changes in the
level of activity
9What is the benefit of understanding how costs
behave?
- Having knowledge of how costs behave is useful
for planning purposes (cost prediction) - Having knowledge of how costs should behave is
useful for control purposes (comparing what
actual costs were to what we thought they should
have been) - Having knowledge of how costs behave is useful
for decision making
10Cost Behavior Basics
- Fundamental to cost behavior is trying to
understand what causes or influences cost changes - Sometimes, management has influence over the
level of cost incurred - Other times, accountants try to determine what is
driving (influencing or causing) cost changes - We refer to the activity or process or output
factor that influences cost behavior as the cost
driver
11Management Influence on Cost Behavior
- Discretionary vs. committed costs
- Discretionary costs are those costs that
management has the option of incurring or not
incurring and at different levels. However, once
the decision has been made as to what level of
cost to incur, they are viewed as fixed,
locked-in costs - an example would be advertising costs or training
costs - Committed costs are the basic costs necessary
just to have the capacity or potential to operate - an example would be the salary of the VP-
Manufacturing
12Fixed Costs
Fixed costs remain unchanged as the activity
level (cost driver) varies. Examples of fixed
costs include rent, salaries and property taxes.
13Example of Fixed Costs
Month Activity Level Total Cost Cost Per
Unit Jan 1200 4,000 3.33 Feb 1400 4,000

21Determining How Costs Behave
- There are several approaches to determining cost
behavior - account classification expert judgment but
subjective, not very analytical - industrial engineering methods works well when
there is a well-defined input-output
relationship, time consuming, intrusive - historical cost analysis
- Focus is usually on mixed costs
22Historical Cost Analysis
- Visual Fit method
- High-low method
- Simple linear regression
23Example of Historical Cost Analysis

26Simple Linear Regression for Cost Estimation
- Accountants take advantage of the power of linear
regression techniques to assist them in cost
estimation - Once again, accountants will assume that the
slope of the regression equation is the variable
cost estimate and that the Y-intercept is the
fixed cost estimate - You should be aware that the Y-intercept data
point is most likely outside of the relevant
range!
27Linear Regression Example
28 Using Historical Data - Comments
- First and foremost, does the relationship between
the activity level (cost driver) and the cost
make sense (is it PLAUSIBLE) - Make sure the data is accurate and available
- Make sure you are using matching time periods
- Be aware of outliers
- Be careful of your interpretation of the results
29Other Ways of Classifying Costs
- Robin Cooper has developed what is referred to as
a cost hierarchy. This was done in response to
observing actual cost behavior and noting that
the simple distinction between fixed and variable
cost was not sufficient - The cost hierarchy
- unit level costs respond to changes in activity
level in a one-to one relationship - batch level cost respond not to individual
changes in activity levels, but changes in the
number of batches - product sustaining level costs respond to
activities related to product lines, not
individual or batch output levels - facility level costs related to the basic
ability of the firm to operate
30Cost Hierarchy
- The cost hierarchy is more reflective of the
relationship that exists between costs and
activity. It is a basic building block for
Activity-Based Costing (ABC) systems - The cost hierarchy will be discussed more as part
of ABC
31Activity Based Costing and Management Systems
- ABC systems focus on the activities and the
business processes as the foundation for
determining the cost of goods, services,
processes, or any cost object - ABC systems attempt to address the problems found
with traditional costing systems, such as
ignoring volume differences, diversity, and
resource demands of different cost objects
32ABC Basics
- ABC systems use the cost hierarchy discussed
earlier unit level, batch level, product
sustaining level, and facility sustaining level - ABC systems, as part of identifying the relevant
activities, also classify these activities into
value-added and non-value added activities, so it
becomes a management tool - ABC systems recognize not only economies of scale
but economies of scope - At the heart of ABC is a two stage allocation
process
33The Two Stage Process in ABC
- Stage 1 Create homogeneous cost pools e.g.,
group all purchasing costs together, all set-up
costs together, all delivery costs together. This
may take some work since most accounting systems
gather cost by account categories such as
salaries, depreciation, supplies, etc. and these
accounts have to be studied in order to break
them down into homogeneous costs pools - Stage 2 Allocate from the cost pools to the cost
object (usually a product) using second stage
cost drivers e.g., number of deliveries, number
of setups
34Mapping Resource Expenses to Activities Stage One
Salaries and Fringes 313,000
Occupancy 111,000
Equipment and Technology 146,000
Materials and Supplies 30,000
Total 600,000

Margin 0.9 1.5 2.8
Other Costs are allocated in proportion to Gross
Margin. Supermarkets share of gross margin is
(108,000/438,000), or 24.66. Thus, Supermarkets
are allocated 24.66 of Other Costs, which equals
74,239.
36An ABC Example, 2
The manager of this pharmaceutical distribution
company heard about ABC and thought it may be
useful for his operations. He identified 5 key
activities, and their corresponding cost
drivers. Activity Cost Driver Order
Processing Number of Orders Line Item
Ordering Number of Line Items Store
Delivery Number of Store Deliveries Cartons
Shipped to Stores Number of Cartons
shipped/delivery Shelf Stacking at Store Number
of hours of shelf stacking
37An ABC Example, 3
Each order consists of one or more line items. A
line item represents a single product (such as
Extra Strength Tylenol. Each Store delivery
entails delivery of one or more cartons of
products. Each product is delivered in one or
more separate cartons. The delivery staff stock
cartons directly onto display shelves in a store.
Currently there is no charge for this service,
and not all customers use this service.

the following costs to each of the five activity

44An ABC Example, 11
- Note that the total profit for the firm has not
changed at all as a result of using ABC vs.
traditional costing techniques - So whats the big deal??
- Some people argue that for many firms using ABC
is analogous to re-arranging the chairs on the
deck of the Titanic - it really doesnt stop a
firm from failing - also, ABC is not GAAP
- also, implementing ABC is a significant task
- This is true if figuring out new product costs is
the only thing ABC is used for
45So What is the Value of ABC
- Like any accounting system, ABC is an INFORMATION
system - it provides info to assist decision
makers, but in and of itself this info DOES
NOTHING, unless management acts upon it - ABC provides insights into your business that
management was probably not aware of before - The old system simply charged each line 68.7
(301,080/438,000) of its gross margin to arrive
at product line profitability - peanut butter
costing
46So What is the Value of ABC, 2
- The ABC system reveals however that the MA and PA
stores actually consume 95.9 of its gross margin
with other operating expenses - This is because the MA and PA stores are more
activity intense, and thus more cost intensive - Under the old system, MA and PA stores were
charged 41.1 (180,000/438,000) of overhead,
since this was their share of gross margin - However, if you look at the activities, you can
see that MA and PA stores account for well over
41.1 of the activities (75 of the orders, 70
of the deliveries, etc)
47How can managers act on this info
- Now that managers know the cost of these
activities, they can work to try and reduce those
costs - Also, they can see why Ma and Pa stores are so
expensive (they order more often, they have more
deliveries, etc.) and they work with these stores
to try and reduce those activities i.e., less
frequent ordering, less frequent deliveries - Also, since part of ABC is activity
identification and classification as VA or NVA,
managers can attempt to eliminate or minimize NVA
48When Would ABC not be Useful(at least from a
product costing view)
- If the company only has one product
- If all products use all resources in the same
proportions, which is the same proportion used to
allocate costs in a traditional system (little
diversity) - Cost control is not critical at this stage for
the company (growth stage companies)
49When Would ABC be most Useful
- The Willie Sutton rule
- large expenses in indirect and support resources
- High diversity (products, customers, processes)
- When a firm wants to better understand its
activities and the costs of those activities,
even if the firm only makes one product
50Economic Characteristics of Costs
- Out-of-pocket cost the cost actually incurred
that required the expenditure of cash or other
assets - Opportunity costs the benefit passed up when
selecting one alternative over another - opportunity costs are ALWAYS relevant in decision
making - Sunk costs the costs incurred in the past and
cannot be altered by any current or future
decision - sunk costs are NEVER relevant in decision making,
but often are erroneously considered relevant - Example
- Marginal Cost
51Example of Opportunity and Sunk Costs
- You have a ticket to the NCAA Mens basketball
championship game you paid 85 (non-refundable)
for the ticket. - What is the out-of-pocket cost for the ticket?
- Scenario 1 You are walking to the game and
someone offers you 120 for your ticket. You
refuse the offer and proceed into the game. - What is the opportunity cost of attending the
game? - Would your answer differ if your out-of-pocket
cost had been 60? What if it had been 150? - Scenario 2 On the day of the game, you become
violently ill and would be better off staying in
bed. However, you decide to go to the game,
arguing that you cant waste 85 just because you
are sick. - The 85 is an example of what type of cost
(besides out-of-pocket)? - If the 85 is not relevant to this decision, what
costs are relevant in the decision to go or not
go to the game?
52Relevant Costs for Decision Making
- When making a decision among alternatives, only
those costs that DIFFER among the alternatives
are relevant - Example You are trying to decide between
offering a summer Bible camp or summer service
camp. The office manager makes 65,000 per year.
Her salary is irrelevant to your decision. - Opportunity costs are always relevant, sunk costs
are never relevant
53Responsibility Accounting
- Costs can be considered controllable or
non-controllable by a manager - Controllable costs are those that a manager has
some influence over - Non-controllable costs are those that a manager
has little or no influence over - A manager should NOT be held responsible for
non-controllable costs
54Decision Making Relevant Costs and Benefits
- Quantitative and qualitative information
- Characteristics of information
- Identifying relevant costs and benefits
- Analysis of special decisions
- Short-run vs. long-run
- Pitfalls to avoid
55Characteristics of information
- Relevance future costs or benefits that are
different between alternatives - Accuracy
- Timeliness
56Identifying relevant costs and benefits
- Sunk costs are never relevant
- Example book value of assets
- Costs/benefits that do not differ between
alternatives are not relevant - Opportunity costs are always relevant
57Short-run vs. long-run
- Time frame does have an impact on decision making
- Some costs that are labeled fixed in the short
run may be variable in the long run - Time value of money becomes relevant
58Pitfalls to avoid
- Sunk Costs
- Fixed costs per unit
- Allocated fixed costs vs. avoidable fixed costs
- Opportunity costs
59Cost Volume Profit (CVP) Analysis
- Once management has developed reasonable cost
estimates, how can that knowledge be useful for
estimating profits? - What is meant by the breakeven point?
- How can the simple concept of breakeven be
extended even further? - Is there a more meaningful way to display
operating results as compared to what you learned
in financial accounting?
60Assumptions of CVP
- Variable costs and revenues are linear and
constant - Fixed cost is constant
- Sales and Production are equal
- If multiple products, the sales mix is constant
- No fundamental changes in the underlying
structure of the business - The analysis is within the relevant range
61The Basic CVP Model
- Revenue (SP/unit X units sold)
- -Variable Costs -(VC/unit X units sold)
- Contribution Margin (CM/unit X units sold)
- -Fixed Costs -FC
- Profit Profit
- This format is known as the contribution format.
It is different than the format you learned in
financial accounting. - Or, (SP-VC)/unit X units sold - FC Profit
62Calculating the Breakeven Point
- (SP-VC)/unit X units sold - FC Profit
- (SP-VC)/unit X units sold FC Profit
- If you are trying to determine the number of
units sold - Units Sold FC Profit
- (SP-VC)/unit
- At breakeven, profit 0
- Units sold FC Breakeven
point - (SP-VC)/unit
63Example of Using CVP
- Program Fee Per Camper 12/unit
- Variable costs (food) 4/unit
- Variable costs (supplies) 3/unit
- Fixed costs (space rental) 600
- Fixed costs (staff member) 900
- Calculate the breakeven point
64Solution to example
- Breakeven point FC
- (SP-VC)/unit
- Breakeven point 1,500
- (12-7)/unit
- Breakeven Point 300 campers
65Extensions of the Basic CVP Model
- Solving for different profit levels, not just the
breakeven point - Solving for any one of the variables, as long as
all the other variables are given (price,
variable cost per unit, fixed cost)
66CVP Example 2
- Program Fee Per Camper 12/unit
- Variable costs (food) 4/unit
- Variable costs (supplies) 3/unit
- Fixed costs (space rental) 600
- Fixed costs (staff member) 900
- Expected number of campers 500
- What should we charge to breakeven?
67Solution to CVP Example 2
- FC
- (Fee-VC)/unit units
- 600900
- (Fee-7)/unit 500 campers
- 1,500 (Fee-VC)/camper 3/camper
- 500 campers
- If VC 7, then Fee would have to be 10/camper
68Final Thoughts on CVP
- CVP is a useful starting point for analyzing
different scenarios - It is limited because of its underlying
assumptions and these need to be remembered while
you are doing the analysis
69Make vs. Buy (Outsourcing)
- The WWW Church prints 2,000 Sunday bulletins each
week at the following costs variable costs 2
per unit fixed costs include a person whose sole
responsibility is to print the bulletins and is
paid 1,000 per week and other weekly fixed costs
allocated to the bulletins equal 600 - Thus, cost per unit equals 2.80 (20002 plus
1600/2,000) - The Just Print Bulletins Co. has offered to print
the bulletins for WWW at a cost of 2.60 - How should the Church print the bulletins?
70Make vs. Buy, 2
- One of the key issues is what will happen to
fixed costs - If nothing happens, then you are comparing a
variable cost of printing the bulletin of 2 to a
cost of paying an outside firm 2.60 - If the supervisors costs go away if we use the
outside service, then what? - Fixed costs that go away are relevant!
- The relevant cost to print the bulletin then is
2.50 (2.00 .50) - This is till cheaper
- If the bid from the outside printer was 2.40,
then it would be cheaper to go with the outside
firm - The allocated fixed costs are irrelevant to the
decision, since they are the same no matter what
our decision
71Make vs. Buy, 4
- Other issues
- Quality of vendors product
- Delivery schedule
- Maintaining/establishing vendor relationships
- Cost control
- Impact on organization of outsourcing
