Introduction
Find how many units you must sell to cover fixed costs given price and variable cost per unit.
Formula
Break-even quantity is fixed costs divided by contribution margin per unit (price minus variable cost).
- F — Total fixed costs
- P — Selling price per unit
- V — Variable cost per unit
- Q — Break-even units
Step-by-step
- Enter total fixed costs.
- Enter selling price per unit.
- Enter variable cost per unit.
- Read break-even units and revenue.
Worked example
With $50,000 fixed costs and $15 contribution per unit, break-even is about 3,333.33 units.
Use cases
- Plan a product launch target
- Check if a price covers costs
- Estimate sales needed before profit
