The Break-Even Point in Units
The controller of More-Power Company has prepared the
following projected income statement:
Sales (72,500 units @ $40)
Less: Variable expenses
Contribution margin
Less: Fixed expenses
Operating income
$2,900,000
1,740,000
$1,160,000
800,000
$ 360,000
3
The Break-Even Point in Units
Operating Income Approach
0 = ($40 x Units) – ($24 x Units) – $800,000
0 = ($16 x Units) – $800,000
$1,740,000 ÷ 72,500
($16 x Units) = $800,000
Units = 50,000
Proof
Sales (50,000 units @ $40)
Less: Variable expenses
Contribution margin
Less: Fixed expenses
Operating income

The Break-Even Point in Units
Contribution Margin Approach
Number of units = $800,000 ÷ ($40 - $24)
= $800,000 ÷ $16 contribution margin per unit
= 50,000
5
The Break-Even Point in Units
Target Income as a Dollar Amount
$424,000 = ($40 x Units) – ($24 x Units) – $800,000
$1,224,000 = $16 x Units
Units = $1,224,000 ÷ $16
= 76,500
Proof
Sales (76,500 units @ $40)
Less: Variable expenses
Contribution margin
Less: Fixed expenses
Operating income
$3,060,000
1,836,000
$1,224,000

The Break-Even Point in Units
Target Income as a Percentage of Sales Revenue
More-Power Company wants to know the number of sanders that
must be sold in order to earn a profit equal to 15 percent of sales
revenue.
0.15($40)(Units) = ($40 x Units) – ($24 x Units) – $800,000
$6 x Units = ($40 x Units) – ($24 x Units) – $800,000
$6 x Units = ($16 x Units) – $800,000
$10 x Units = $800,000
Units = 80,000
7
The Break-Even Point in Units
After-Tax Profit Targets
Net income = Operating income – Income taxes
= Operating income – (Tax rate × Operating income)
= Operating income × (1 – Tax rate)
Or
Net income
Operating income =
(1 - Tax rate)
8
The Break-Even Point in Units
After-Tax Profit Targets
More-Power Company wants to achieve net income of
$487,500 and its income tax rate is 35 percent.
$487,500 = Operating income – 0.35(Operating income)
$487,500 = 0.65(Operating income)
$750,000 = Operating income
Units = ($800,000 + $750,000) ÷ $16
= $1,550,000 ÷ $16
= $96,875

Break-Even Point in Sales Dollars
To determine the break-even in sales dollars, the contribution
margin ratio must be determined ($1,160,000 ÷ $2,900,000)
Sales

Break-Even Point in Sales Dollars
Operating income = Sales – Variable costs – Fixed Costs
0 = Sales – (Variable cost ratio × Sales) – Fixed costs
0 = Sales × (1 – Variable cost ratio) – Fixed costs
0 = Sales × (1 – .60) – $800,000
Sales × 0.40 = $800,000
Sales = $2,000,000

Profit Targets
How much sales revenue must More-Power generate to earn a
before-tax profit of $424,000?
Sales = ($800,000 + $424,000) ÷ 0.40
= $1,224,000 ÷ 0.40
= $3,060,000

Multiple-Product Analysis
Break-Even Point in Units
Regular sander break-even units
= Fixed costs ÷ (Price – Unit variable)
= $250,000 ÷ $16
= 15,625 units
Mini-sander break-even units
= Fixed costs ÷ (Price – Unit variable)
= $450,000 ÷ $30
= 15,000 units

Assumptions of C-V-P Analysis
1.
2.
3.
4.
5.
The analysis assumes a linear revenue function and
a linear cost function.
The analysis assumes that price, total fixed costs,
and unit variable costs can be accurately identified
and remain constant over the relevant range.
The analysis assumes that what is produced is sold.
For multiple-product analysis, the sales mix is
assumed to be known.
The selling price and costs are assumed to be
known with certainty.
25
Changes in the CVP Variables
Alternative 1: If advertising expenditures increase by
$48,000, sales will increase from 72,500 units to
75,000 units.
26
Changes in the CVP Variables
Alternative 2: A price decrease from $40 per sander
to $38 would increase sales from 72,500 units to
80,000 units.
27
Changes in the CVP Variables
Alternative 3: Decreasing price to $38 and increasing
advertising expenditures by $48,000 will increase sales
from 72,500 units to 90,000 units.

CVP Analysis and
Activity-Based Costing
• Differences between ABC break-even and
conventional break-even
– Fixed costs differ
• Costs by vary with non-unit cost drivers
– The numerator of the ABC break-even
equation has two nonunit-variable cost terms
• Batch-related activities
• Product-sustaining activities

Same data using the ABC
Units = ($20,000 + $50,000 + $20,000 + $30,000) ÷ ($20 – $10)
= $120,000 ÷ $10

35
CVP Analysis and
Activity-Based Costing
Example Comparing Conventional and ABC Analysis
Suppose that marketing indicates that only 10,000 units can
be sold. A new design reduces direct labor by $2 (thus, the
new variable cost is $8). The new break-even is :
Units = Fixed costs ÷ (Price – Unit variable cost)
= $100,000 ÷ ($20 – $8)
= 8,333
36
CVP Analysis and
Activity-Based Costing
Example Comparing Conventional and ABC Analysis
Projected income if 10,000 units are sold:

CVP Analysis and
Activity-Based Costing
Example Comparing Conventional and ABC Analysis
Suppose that the new design requires a more complex
setup, increasing the cost per setup from $1,000 to $1,600.
Also, suppose that the new design requires a 40 percent
increase in engineering support.
New cost equation:
