Learning Objective 1
Understand the assumptions
underlying cost-volume-profit
(CVP) analysis.
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3-2
Cost-Volume-Profit Assumptions
and Terminology
1. Changes in the level of revenues and costs arise
only because of changes in the number of product
(or service) units produced and sold.
2. Total costs can be divided into a fixed component
and a component that is variable with respect to
the level of output.
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3-3
Cost-Volume-Profit Assumptions
and Terminology
3. When graphed, the behavior of total revenues
and total costs is linear (straight-line) in relation
to output units within the relevant range
(and time period).
4. The unit selling price, unit variable costs, and
fixed costs are known and constant.
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3-4
Cost-Volume-Profit Assumptions
and Terminology
5. The analysis either covers a single product or
assumes that the sales mix when multiple
products are sold will remain constant as the
level of total units sold changes.
6. All revenues and costs can be added and
compared without taking into account the time
value of money.

Cost-Volume-Profit Assumptions
and Terminology
Operating income
= Total revenues from operations
– Cost of goods sold and operating costs
(excluding income taxes)
Net income = Operating income – Income taxes

Learning Objective 2
Explain the features
of CVP analysis.

3-7
Essentials of Cost-Volume-Profit
(CVP) Analysis Example
Assume that the Pants Shop can purchase pants
for $32 from a local factory; other variable costs
amount to $10 per unit.
The local factory allows the Pants Shop to
return all unsold pants and receive a full $32
refund per pair of pants within one year.
The average selling price per pair of pants is $70
and total fixed costs amount to $84,000.
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3-8
Essentials of Cost-Volume-Profit
(CVP) Analysis Example
How much revenue will the business receive if
2,500 units are sold?
2,500 × $70 = $175,000
How much variable costs will the business incur?
2,500 × $42 = $105,000
$175,000 – 105,000 – 84,000 = ($14,000)
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3-9
Essentials of Cost-Volume-Profit
(CVP) Analysis Example
What is the contribution margin per unit?
$70 – $42 = $28 contribution margin per unit
What is the total contribution margin when
2,500 pairs of pants are sold?
2,500 × $28 = $70,000
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3 - 10
Essentials of Cost-Volume-Profit
(CVP) Analysis Example
Contribution margin percentage (contribution
margin ratio) is the contribution margin per
unit divided by the selling price.
What is the contribution margin percentage?
$28 ÷ $70 = 40%
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3 - 11
Essentials of Cost-Volume-Profit
(CVP) Analysis Example
If the business sells 3,000 pairs of pants,
revenues will be $210,000 and contribution
margin would equal 40% × $210,000 = $84,000.

Equation Method
(Selling price × Quantity sold) – (Variable unit cost
× Quantity sold) – Fixed costs = B/E in units
Let Q = number of units to be sold to break even
$70Q – $42Q – $84,000 = 0
$28Q = $84,000
Q = $84,000 ÷ $28 = 3,000 units
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3 - 17
Contribution Margin Method
(Fixed Costs ÷ CMU) = Breakeven point in units
$84,000 ÷ $28 = 3,000 units
Breakeven revenues = FC ÷ CM%
$84,000 ÷ [(28 ÷ 70) x 100] = $210,000
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3 - 18
Graph Method
1. Draw the Total Cost line
a. Start with the point at which the fixed cost intersects the vertical axis
($84,000 in our example)
b. Select a second point on the TC line. You need a second Q. For example,
assume Q = 2,000. TC = 42Q + $84,000 . TC = 168,000. Plot this point on
the graph. Extend a line horizontally from the first point in (a) above
through the second point as now calculated. This is the TC line.
2. Draw the Total Revenue line
a. Begin with the point ‘0’ on the graph where the two axes intersect
b. Select a quantity (you may use the same as for TC) and compute TR. Plot
point on the graph and extend a line from the (a) above through this new
point on the graph. This is now your TR line

Target Operating Income
(Fixed costs + Target operating income)
divided either by Contribution margin
percentage or Contribution margin per unit

3 - 21
Target Operating Income
Assume that management wants to have an
operating income of $14,000.
How many pairs of pants must be sold?
Units to be sold = (Fixed Costs + Target Income) ÷ CMU
($84,000 + $14,000) ÷ $28 = 3,500
What dollar sales are needed to achieve this income?
Revenue needed = (Fixed Costs + Target Income) ÷ CM%
($84,000 + $14,000) ÷ 40% = $245,000
** Remember CM% = (Price – VC per unit) x 100**

Learning Objective 4
Understand how income
taxes affect CVP analysis.

3 - 23
Target Net Income
and Income Taxes Example
Management would like to earn
an after tax income of $35,711.
The tax rate is 30%.
What is the target operating income?
Target operating income
= Target net income ÷ (1 – tax rate)
TOI = $35,711 ÷ (1 – 0.30) = $51,016

Explain CVP analysis
in decision making and
how sensitivity analysis helps
managers cope with uncertainty.
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3 - 27
Using CVP Analysis Example
Suppose the management anticipates
selling 3,200 pairs of pants.
Management is considering an advertising
campaign that would cost $10,000.
It is anticipated that the advertising will
increase sales to 4,000 units.
Should the business advertise?

$ 18,000
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3 - 29
Using CVP Analysis Example
Instead of advertising, management is
considering reducing the selling price
to $61 per pair of pants.
It is anticipated that this will increase
sales to 4,500 units.
Should management decrease the selling
price per pair of pants to $61?

3 - 30
Using CVP Analysis Example
3,200 pairs of pants sold with no change
in the selling price:
Operating income = $5,600

Sensitivity Analysis and
Uncertainty Example
Assume that the Pants Shop can sell
4,000 pairs of pants.
Fixed costs are $84,000.
Contribution margin ratio is 40%.
At the present time the business cannot
handle more than 3,500 pairs of pants.
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3 - 32
Sensitivity Analysis and
Uncertainty Example
To satisfy a demand for 4,000 pairs, management
must acquire additional space for $6,000.
Should the additional space be acquired?
Revenues at breakeven with existing space are
$84,000 ÷ .40 = $210,000.
Revenues at breakeven with additional space are
$90,000 ÷ .40 = $225,000
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3 - 33
Sensitivity Analysis and
Uncertainty Example
Operating income at $245,000 revenues with
existing space = ($245,000 × .40)
– $84,000 = $14,000.
(3,500 pairs of pants × $28) – $84,000 = $14,000
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3 - 34
Sensitivity Analysis and
Uncertainty Example
Operating income at $280,000 revenues with
additional space = ($280,000 × .40) – $90,000
= $22,000.
(4,000 pairs of pants × $28 contribution margin)
– $90,000 = $22,000

Alternative Fixed/Variable Cost
Structures Example
Suppose that the factory the Pants Shop is using to
obtain the merchandise offers the following:
Decrease the price they charge from $32 to $25 and
charge an annual administrative fee of $30,000.
What is the new contribution margin?
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3 - 37
Alternative Fixed/Variable Cost
Structures Example
$70 – ($25 + $10) = $35
Contribution margin increases from $28 to $35.
What is the contribution margin percentage?
$35 ÷ $70 = 50%
What are the new fixed costs?
$84,000 + $30,000 = $114,000
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3 - 38
Alternative Fixed/Variable Cost
Structures Example
Management questions what sales volume
would yield an identical operating income
regardless of the arrangement.
28x – 84,000 = 35x – 114,000
114,000 – 84,000 = 35x – 28x
7x = 30,000
x = 4,286 pairs of pants
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster

Alternative Fixed/Variable Cost
Structures Example
Cost with existing arrangement
= Cost with new arrangement
.60x + 84,000 = .50x + 114,000
.10x = $30,000  x = $300,000
($300,000 × .40) – $ 84,000 = $36,000
($300,000 × .50) – $114,000 = $36,000

Effects of Sales Mix on Income
Pants Shop Example
Management expects to sell 2 shirts at $20 each
for every pair of pants it sells.
This will not require any additional fixed costs.

3 - 42
Effects of Sales Mix on Income
Contribution margin per shirt: Price – VC per unit
$20 – $9 = $11
What is the contribution margin of the mix?
CMU for pants + CMU for shirts
$28 + (2 × $11) = $28 + $22 = $50
*** The $28 is from the previous slides**

Effects of Sales Mix on Income
$84,000 fixed costs ÷ $50 = 1,680 packages
1,680 × 2 = 3,360 shirts
1,680 × 1 = 1,680 pairs of pants
Total units = 5,040

Effects of Sales Mix on Income
What is the weighted-average budgeted
contribution margin?
Pants: 1 × $28 + Shirts: 2 × $11
= $50 ÷ 3 = $16.667
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
3 - 46
Effects of Sales Mix on Income
The breakeven point for the two products is:
$84,000 ÷ $16.667 = 5,040 units
5,040 × 1/3 = 1,680 pairs of pants
5,040 × 2/3 = 3,360 shirts

Effects of Sales Mix on Income
Now, let’s assume the sales mix in dollars
is 63.6% pants and 36.4% shirts.
Weighted contribution would be:
40% × 63.6% = 25.44% pants
55% × 36.4% = 20.02% shirts
45.46%

Effects of Sales Mix on Income
Breakeven sales dollars is $84,000
÷ 45.46% = $184,778 (rounding).
$184,778 × 63.6% = $117,519 pants sales
$184,778 × 36.4% = $ 67,259 shirt sales
