Fixed, variable, and contribution margin
Fixed costs (rent, salaries, insurance) don't change with sales volume; variable costs (materials, per-unit shipping) scale directly with each unit sold. Contribution margin — price minus variable cost — is what each sale contributes toward covering fixed costs. Once cumulative contribution margin equals fixed costs, you've broken even; every unit after that is profit, which is exactly where the revenue and cost lines cross in the chart above.
Frequently asked questions
What's the difference between fixed and variable costs?
Fixed costs don't change with sales volume — rent, salaries, insurance. Variable costs scale with each unit sold — materials, per-unit shipping, sales commissions. Break-even analysis needs both split out correctly to be accurate.
What's contribution margin?
Price per unit minus variable cost per unit — the amount each sale contributes toward covering fixed costs before you start generating profit. It's the key number this calculator uses to find your break-even volume.
