How to calculate
Find how many units cover your fixed costs.
Break-even units = fixed costs ÷ (price − variable cost), rounded up
Worked example
Fixed costs: 10000; Selling price per unit: 50; Variable cost per unit: 30.
Units to break even: 500 ; Revenue at break-even units: 25,000 .
Assumptions and limits
Assumes constant price and cost per unit. Selling price must exceed variable cost.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
The unit count covers fixed costs using each unit’s contribution: selling price minus variable cost. Fractional units are rounded up.
When this tool is useful
Estimate a minimum sales volume for a product with a constant selling price and unit cost.
Understanding your inputs
| Input | What to enter |
|---|---|
| Fixed costs | Enter a number of at least 0 and no more than 1000000000000. |
| Selling price per unit | Enter a number of at least 0.000001 and no more than 1000000000000. |
| Variable cost per unit | Enter a number of at least 0 and no more than 1000000000000. |
Frequently asked questions
What if variable cost is as high as the price?
There is no positive contribution to fixed costs. A finite break-even sales volume cannot be found under those assumptions.
Does selling the break-even quantity guarantee profit?
It covers the entered costs in this simplified model. Additional costs, unsold stock, or changing unit economics can alter the outcome.
