About this tool
Before a product makes a profit it has to cover its costs, and the break-even point tells you exactly when that happens. This calculator divides your fixed costs by the contribution margin — price minus variable cost — to show how many units you must sell, and the revenue that represents.
It’s a fundamental check for pricing, budgeting and business plans: if the break-even volume looks unrealistic, the numbers need rethinking. Everything is computed in your browser.
Frequently asked questions
What is the contribution margin?
It's the price minus the variable cost per unit — the amount each sale contributes toward covering your fixed costs.
Why must price exceed variable cost?
If each unit costs more to make than it sells for, you lose money on every sale and can never break even, however much you sell.
