How to use the Break-Even Calculator

1Enter fixed costs. Costs that don't change with volume — rent, salaries, software, insurance.

3Enter variable cost per unit. The per-unit cost that scales with production — materials, shipping, fees.

Frequently asked questions

What is the break-even formula?

Break-even units = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit). The denominator is your contribution margin per unit.

What is contribution margin?

It's the price per unit minus the variable cost per unit — the amount each sale contributes toward covering fixed costs. If it's zero or negative, you can't break even at that price.
