Cost-Volume-Profit Analysis
QUESTIONS
1. A variable cost is one that varies proportionately with the volume of activity. For
2. Variable costs per unit stay the same (remain constant) when output volume
changes. This is because each unit consumes the same amount of variable costs
within the relevant range of activity.
3. Fixed costs per unit decrease when output volume increases. This is because the
4. Cost-volume-profit analysis is especially useful in the planning phase for a
5. A step-wise cost remains constant over a limited range of output activity, outside of
6. Contribution margin ratio means that for each sales dollar a specified percent is
7. Definition: Contribution margin ratio = Contribution margin / Sales price per unit.
8. Definition: Unit contribution margin = Sales price per unit - Variable costs per unit.
Unit contribution margin is the per unit dollars available to cover fixed costs, with
the remainder being profit.
9. A CVP analysis for a manufacturing company is simplified by assuming that the

10. The first is that although individual costs classified as fixed or variable might not
behave precisely in those patterns, some variations of individual components in the
11. By assuming a relevant range for operating activity, management can more
justifiably assume either fixed or variable relations between costs and volume, and
12. Three common methods for measuring cost behavior are: the scatter diagram, the
high-low method, and least-squares regression.
13. A scatter diagram is used to display the relation between past costs and sales
14. At break-even, profits are zero. Break-even is the point where sales equals fixed
plus variable costs.
15. This line represents total cost, which equals the sum of the fixed and variable costs
16. Fixed costs are depicted as a horizontal line on a CVP chart because they remain the
same (constant) at all volume levels within the relevant range.
17. Company A has a contribution margin of 50% [($20,000 – $10,000) / ($20,000)] and
Company B has a contribution margin of 80% [($20,000 – $4,000) / ($20,000)]. This
18. Margin of safety reflects the expected sales in excess of the level of break-even
sales.

manufacturing and inventory-related costs. The costs of operating the plant and
