What is the contribution margin per unit and why is it important?

• A. Price minus variable cost; indicates how much each unit contributes to fixed costs and profit
• B. Gross profit margin
• C. Net income per unit
• D. Price minus fixed costs

Answer: (A)

Contribution margin per unit shows how much each unit sale contributes to covering fixed costs and to profit. It’s calculated as the selling price per unit minus the variable cost per unit. This matters because fixed costs must be covered before you can earn profit, and the contribution margin tells you how much of every sale is available for that purpose after paying variable costs. It’s essential for break-even analysis—divide fixed costs by the contribution margin per unit to find the number of units you must sell to break even. For example, selling a unit for 50 with a variable cost of 30 yields a 20 contribution margin per unit; with fixed costs of 1,000, you’d need 50 units to break even. Knowing this margin also helps with pricing decisions, cost control, and evaluating different product lines, since higher margins make it easier to cover fixed costs and earn profit. The other concepts either bundle fixed costs into the per-unit figure or exclude variable costs, so they don’t precisely capture what each unit contributes toward fixed costs and profit.
