Cost-Volume-Profit Analysis: Additional Issues
FOR INSTRUCTOR USE ONLY
CHAPTER LEARNING OBJECTIVES
1. Describe the essential features of a cost–volume-profit income statement. The CVP
income statement classifies costs and expenses as variable or fixed and reports contribution
margin in the body of the statement.
2. Apply basic CVP concepts. Contribution margin is the amount of revenue remaining after
deducting variable costs. It can be expressed as a per unit amount or as a ratio. The break–
even point in units is fixed costs divided by contribution margin per unit. The break-even
point in dollars is fixed costs divided by the contribution margin ratio. These formulas can
also be used to determine units or sales dollars needed to achieve target net income, simply
by adding target net income to fixed costs before dividing by the contribution margin. Margin
of safety indicates how much sales can decline before the company is operating at a loss. It
can be expressed in dollar terms or as a percentage.
3. Explain the term sales mix and its effects on break-even sales. Sales mix is the relative
proportion in which each product is sold when a company sells more than one product. For a
company with a small number of products, break-even sales in units is determined by using
the weighted-average unit contribution margin of all the products. If the company sells many
different products, then calculating the break-even point using unit information is not
practical. Instead, in a company with many products, break-even sales in dollars is
calculated using the weighted-average contribution margin ratio.
4 Determine sales mix when a company has limited resources. When a company has
limited resources, it is necessary to find the contribution margin per unit of limited resource.
This amount is then multiplied by the units of limited resource to determine which product
maximizes net income.
5. Understand how operating leverage affects profitability. Operating leverage refers to the
degree to which a company’s net income reacts to a change in sales. Operating leverage is
determined by a company’s relative use of fixed versus variable costs. Companies with high
fixed costs relative to variable costs have high operating leverage. A company with high
operating leverage will experience a sharp increase (decrease) in net income with a given
increase (decrease) in sales. The degree of operating leverage can be measured by dividing
contribution margin by net income.
a6. Explain the difference between absorption costing and variable costing. Under
absorption costing, fixed manufacturing costs are product costs. Under variable costing, fixed
manufacturing costs are period costs.
a7. Discuss net income effects under absorption costing versus variable costing. If
production volume exceeds sales volume, net income under absorption costing will exceed
net income under variable costing by the amount of fixed manufacturing costs included in
ending inventory that results from units produced but not sold during the period. If production
volume is less than sales volume, net income under absorption costing will be less than
under variable costing by the amount of fixed manufacturing costs included in the units sold
during the period that were not produced during the period.
a8. Discuss the merits of absorption versus variable costing for management decision–
making. The use of variable costing is consistent with cost-volume-profit analysis. Net
income under variable costing is unaffected by changes in production levels. Instead, it is
closely tied to changes in sales. The presentation of fixed costs in the variable costing
approach makes it easier to identify fixed costs and to evaluate their impact on the
company’s profitability.
