What this calculator does
Calculates how many units you need to sell to cover your fixed costs, plus the revenue at that break-even point, from fixed costs, price per unit and variable cost per unit.
How to use it
Enter your total fixed costs, the selling price per unit and the variable cost per unit. Price must exceed variable cost for a break-even point to exist. Results update as you type.
Worked example
With 10,000 in fixed costs, a 50 price per unit and a 30 variable cost per unit, the contribution margin is 20. Break-even is 500 units, for revenue of 25,000 at that point.
Formulas used
Contribution margin = price per unit − variable cost per unit. Break-even units = fixed costs ÷ contribution margin. Break-even revenue = break-even units × price per unit.
Rounding
Displayed break-even units are rounded up to the next whole unit, since you can't sell a fraction of a unit, while the revenue figure is based on the unrounded theoretical result — reconcile it against whole units before relying on it.
Limitations
The model assumes a constant price, variable cost and fixed cost regardless of volume, and excludes tax, production capacity limits, stepped costs and changes in demand at different price points.

Frequently Asked Questions
- How is the break-even point calculated?
- Break-even units = fixed costs / (price per unit − variable cost per unit). Revenue at break-even is units × price.
- What if price equals variable cost?
- If the price per unit doesn't exceed the variable cost per unit, there's no contribution margin and break-even is never reached, however many units you sell.
- Does this include one-time startup costs?
- Include any one-time costs in your fixed costs figure if you want them factored into the break-even point.
