Contribution margin ratio:
Calculate contribution margin as a percentage of selling price.

Total contribution margin:
Multiply contribution margin per unit by units sold.

Target profit sales:
Enter fixed costs and target profit to calculate the units and revenue needed to reach that goal.

Why use a contribution margin calculator?

A contribution margin calculator helps with pricing, break-even analysis, product profitability, sales planning, cost control, and target-profit forecasting.

It can show whether each sale contributes enough to cover fixed costs and eventually create profit.

What your result means

Your result shows contribution margin per unit, contribution margin ratio, total contribution margin, break-even units, profit, target-profit units, and target-profit revenue. A higher contribution margin means each sale contributes more toward covering fixed costs and profit.
