Cost-Volume-Profit Analysis: A Managerial Planning Tool
Chapter Three
Fundamental Cornerstones of Managerial Accounting

Cost-Volume-Profit Analysis
A powerful tool for planning and decision making. It can be used to calculate:
The number of units that must be sold to
break-even
The impact of a given reduction in fixed
costs on the break-even point.
The impact of an increase in price on
profit.
3
Break-Even Point
Total Revenue
Or to put it another way:
– Total Cost
=
Total Revenue
Zero Profit
Total Cost
4
Contribution Margin
Sales - Variable Expense
Contribution Margin
=
Contribution Margin is then used to cover Fixed Costs
and Operating Income.
Using Operating Income inCost-Volume-Profit Analysis
5
Contribution Margin Income Statement
• Divides costs based on behavior
• Costs are divided into variable and fixed components
• Important subtotal is contribution margin
◦ Sales revenue minus variable expenses
6
Contribution Margin
Sales - Variable Expense
Contribution Margin
=
Break-even point is when Operating Income is zero.
Contribution Margin -
Fixed Costs =
Operating Income
7
Units to Be Sold to Achieve a Target Income
Two ways:
1.Using Operating Income equation2.Using the Basic Break-even equation
Cornerstone 4-5 will walk us through these computations
8
Number of units to earn target
income =
Fixed Cost + Target Income
$400 - $325
Price – Variable Cost per unit
$45,000 + $37,500 =
Units to Be Sold to Achieve a Target Income

Profit-Volume Graph
• Visually portrays the relationship between profits and units sold
• Operating Income is the dependent variable
• Units sold is the independent variable
11
Cost-Volume-Profit Graph
• Depicts the relationship among cost, volume, and profits
• To obtain the more detailed relationships, it is necessary to graph two separate lines:
◦ Total revenue
◦ Total cost
• The vertical axis is measured in dollars
• The horizontal axis is measured in units sold
12
Assumptions of Cost-Volume-Profit Analysis
• Revenue and cost functions are linear
• Price, total fixed costs, and unit variable costs can be identified and remain constant over relevant range
• All units produced are sold-there are no change in inventory levels
• Sales mix is constant
• Selling prices and costs are known with certainty
13
Linear Cost and Revenue Functions
Cost-Volume-Profit assumes that cost and revenue functions are linear. In other words they are straight lines.
14
Production Equal to Sales
• Cost-Volume-Profit assumes that what is produced is actually sold
• Inventory levels do not change over the period
• CVP focuses on current costs by excluding inventory costs of previous periods
15
Constant Sales Mix
Multiple product break-even analysis requires a constant sales mix.
Relative combination of products being sold by a firm
Sales mix is difficult to predict with certainty
16
Certainty of Prices and Costs
In actuality, firms seldom know prices, variable costs, and fixed costs with certainty. There are formal ways of
explicitly building uncertainty into the Cost-Volume-Profit model.
17
Multiple-Product Analysis
Cost-Volume-Profit analysis becomes more complex with multiple products.
We need to adapt the single-product formulas.
18
Direct Fixed Expenses
Those fixed costs that can be traced to each segment and would be avoided if the
segment did not exist.
19
Common Fixed Expenses
The fixed costs that are not traceable to the segments and would remain even if
one of the segments was eliminated.
20
Multiple-Product Analysis
Key is to identify the expected sales mix.
Sales mix is the relative combination of products being sold by a firm.
Break-even point in units
21
Sales Mix
• Measured in units sold
• Reduced to the smallest possible whole numbers
• Required in order to determine break even point in units
22
Changes in any of the above will affect the sales mix.
CVP Analysis: Risk and Uncertainty
• The break-even point can be affected by changes in:
◦ Price
◦ Unit contribution margin
◦ Fixed cost
23
Risk and Uncertainty Effects on Managers
• Management must realize the uncertain nature of future prices, costs, and quantities.
• Managers move from consideration of a break-even point to what might be called a “break-even band”.
• Managers may engage in sensitivity or what-if analysis.
24
Margin of Safety
• The units sold or the revenue earned above the break-even volume.
• Can be viewed as a crude measure of risk.
◦ When there is a downturn in sales, the risk of suffering losses will be less if the firm’s margin of safety is large than if the margin of safety is small.
25
Margin of Safety
Margin of Safety in units =
Sales in units
Break-even units-
Margin of Safety in units = 1,000 - 600
Margin of Safety in units = 400
26
Margin of Safety
Margin of Safety in sales revenue = Sales
Break-even sales -
Margin of Safety in sales revenue = $400(1,000) - $400(600)
Margin of Safety in sales revenue = $160,000
27
Operating Leverage
• The relative mix of fixed costs to variable costs in a company
• Higher proportions of fixed costs to the amount of variable costs create higher operating leverage
• The greater the degree of operating leverage, the larger the effect on operating income when sales change
Degree of Operating Leverage Operating Income
Contribution Margin=
28
The degree of operating leverage (DOL) can be measured for a given level of sales.
