Costs that stay the same for the period whether you sell one unit or many — rent, insurance and base salaries are common examples.
What a customer pays for one unit, before tax.
The cost that rises by this amount for each unit sold — materials, packaging and per-sale fees are common examples.
Contribution margin is price per unit minus variable cost per unit. Break-even units are fixed costs divided by that margin.
The formula. Contribution margin per unit = price per unit − variable cost per unit. Break-even units = fixed costs ÷ contribution margin per unit, rounded up to the next whole unit. Break-even revenue = break-even units (exact, before rounding) × price per unit. Contribution margin as a share of price = contribution margin per unit ÷ price per unit.
Assumptions printed. The result uses exactly the three numbers you entered, for one period, with no tax and no change in price or costs across the period.
