How to use this calculator

- Choose Calculate or press Enter in a single-line field.
- Review the result and the assumptions below before using it.
Formula and method
Break-even units = fixed costs / (price per unit − variable cost per unit). Round up for whole units.
Worked example
Fixed costs of 10,000 and a contribution of 20 per sale require 500 units, or 25,000 revenue.
What the result assumes
Prices and variable costs must stay constant. The model assumes one product or a stable sales mix.
Common question
What happens when the price is below variable cost?
Each sale adds a loss, so there is no finite break-even volume under these assumptions.
