Cost-Volume-Profit AnalysisCost-Volume-Profit Analysis
Purpose of BudgetingPurpose of Budgeting
Planning• How many units of input do I need
to support a budgeted output? Control• Are operations effective and
efficient? Decision making• How do we decide on a price, and
choose quantity given constraints?
Learning objective 1: Identify common cost behavior patterns
Variable Costs Costs which change directly in
proportion to changes in quantity or activity
Fixed Costs Costs which do not change when
quantity or activity volume changes
Common Cost Behavior Patterns

Mixed Costs Costs that have both variable and
fixed elements
Step Costs Fixed for a range of output, but
increase when upper bound of range is exceeded

Learning objective 1: Identify common cost behavior patterns
Variable CostsVariable Costs
Costs that change in proportion to changes in volume or activity
An automobile manufacturer will need 400 tires to make 100 cars, but 4,000 tires to make 1,000 cars
A bakery will need 2 eggs to make 1 cake and 20 eggs to make 10 cakes
If activity increases by 10%, cost increases by 10%
Learning objective 1: Identify common cost behavior patterns
Variable CostsVariable Costs
A company has decided that direct labor costs are 100% variable. Last month total direct labor costs were $125,000 and total direct labor hours worked were 10,000.1.What is the direct labor cost per hour?
$125,000 / 10,000 hours = $12.50 per hour
2.Predict labor costs in a month when 12,000 labor hours are worked
$12.50 per hour × 12,000 hours = $150,000
Learning objective 1: Identify common cost behavior patterns
Variable CostsVariable Costs
Total Variable Cost = $91 × Units produced
Learning objective 1: Identify common cost behavior patterns
Fixed CostsFixed Costs
Do not change in response to changes in activity level
Typical fixed costs are depreciation, supervisory salaries, and building maintenance• Rent for a bakery will not double if
output increases from 100 to 200 cakes
Activity increases by 10%, costs remain unchanged
Learning objective 1: Identify common cost behavior patterns
Fixed CostsFixed Costs
Total fixed cost = $94,000
Learning objective 1: Identify common cost behavior patterns
Fixed CostsFixed Costs
Discretionary Fixed Costs Management can easily change Advertising, research and
development• Many companies cut back on these costs
when sales drop. This can be shortsighted. Why?
Committed Fixed Costs Cannot be easily changed Rent, insurance
Learning objective 1: Identify common cost behavior patterns
Fixed CostsFixed Costs
1.What happens to cost per unit when fixed costs remain the same but volume or activity declines?
2.Can you think of another way to set rates to make ratepayers less angry?
Learning objective 1: Identify common cost behavior patterns
LINK TO PRACTICE
Using Less Water but Paying Higher Rates!
Mixed CostsMixed Costs
Contain both variable and fixed cost elements
Can separate mixed costs into variable and fixed components

Cost Estimation MethodsCost Estimation Methods
Account Analysis-Classify costs into variable and fixed
pools Scattergraphs
-Can see cost relationships visually High-Low Method
-Linear estimation connects high and low volume observations
Regression Analysis-Linear estimation is best fit to observed
valuesLearning objective 2: Estimate the relation between cost and activity using account analysis and the high-low method
Account AnalysisAccount Analysis
Most common approach Requires professional judgment
of management Management classifies costs as
fixed, variable, or mixed• Total variable costs divided by
activity equals variable cost per unit• Variable cost per unit and total fixed
costs can be used in cost equation

Connect straight line from lowest activity level to highest activity level• Slope of the line (change in cost
divided by change in activity) equals variable cost per unit
• Total cost at lowest or highest activity level minus variable cost at that level equals fixed cost

Gabby’s Wedding Cakes creates elaborate wedding cakes. Each cake sells for $500. The variable cost of baking the cakes is $200 and the fixed cost per month is $6,000
1.Calculate the break-even point in units
$6,000 / ($500 - $200) = 20 cakes
2. How many cakes must be sold to earn a profit of $9,000?
($9,000 + $6,000) / ($500 - $200) = 50 cakes

Margin of SafetyMargin of Safety
The margin of safety is the difference between the expected level of sales and break-even sales
• If breakeven sales for Model DX375 is $293,600 and expected sales are $350,000, calculate the margin of safety.
• The margin of safety is:
$350,000 - $293,600 = $56,400.

Contribution MarginContribution Margin
Difference between revenue and variable costs
Contribution margin =Total revenue minus total variable costs
Unit contribution margin =Selling price minus variable cost per unit
- The unit contribution margin measures the amount of incremental profit generated by selling an additional unit
Learning objective 3: Perform cost-volume profit analysis for single products
Contribution Margin RatioContribution Margin Ratio
The contribution margin ratio measures the amount of incremental profit generated by an additional dollar of sales
Two methods to calculate the contribution margin ratio1. Contribution margin divided by
sales revenue (Sales – TVC) / Sales2. Unit contribution margin divided by
selling price (SP – VC) / SP

Rhetorix, Inc. produces stereo speakers. The selling price per pair of speakers is $800. The variable cost of production is $300 and the fixed cost per month is $50,000.
1.Calculate the unit contribution margin associated with a pair of speakers
$800 – $300 = $500 2.Calculate the contribution margin ratio
for Rhetorix associated with a pair of speakers
($800 – $300) / $800 = 0.625
Learning objective 3: Perform cost-volume profit analysis for single products
Contribution MarginContribution Margin Using the contribution margin and the
contribution margin ratioSP = $200.00, VC = $90.83, CM = 200 – 90.83 = $109.17, TFC = 160,285, profit = $40,000
Units to produce = (Profit + TFC) / Unit contribution margin
($40,000 + $160,285) / 109.17 = 1,835 units
Sales required (in dollars) = (Profit + TFC) / Contribution margin ratio
CM ratio = $109.17 / $200.00 = 0.5459($40,000 + $160,285) / 0.5459 = $366,890

Assumptions in CVP Analysis
Assumptions in CVP Analysis
Assumptions can affect the validity of the analysis1. Costs can be separated into fixed
and variable components2. Total fixed cost and unit variable
cost do not change over the levels of interest
3. Multiproduct analysis assumes the product mix does not change
Despite assumptions, CVP is useful

Operating LeverageOperating Leverage
Level of fixed versus variable costs in a company
High level of fixed costs has a high operating leverage- Companies with high operating
leverage have large fluctuations in profit when sales increase or decrease
Learning objective 5: Discuss the effect of operating leverage
