How to use the Break-Even Calculator
Enter the fixed costs, selling price per unit and variable cost per unit and the result appears straight away. Everything runs in your browser, so nothing you type is uploaded.
The formula
Break-even units = fixed costs ÷ (selling price − variable cost).
Examples
- Fixed 10,000, price 50, variable 30
Break-even volume: 500.00 units Whole units to break even: 500 Break-even revenue: 25,000
- Fixed 4,200, price 18, variable 7.50
Break-even volume: 400.00 units Whole units to break even: 400 Break-even revenue: 7,200
- Fixed 75,000, price 400, variable 260
Break-even volume: 535.71 units Whole units to break even: 536 Break-even revenue: 214,400
Limitations and assumptions
Assumes constant costs and price, one product and no sales mix, tax or capacity constraints.
Frequently asked questions
What is the break-even formula?
Units = fixed costs ÷ (price − variable cost per unit).
What is the contribution margin?
Price minus variable cost, the amount each unit contributes toward fixed costs.
What if the price is below variable cost?
Break-even is impossible because each sale adds to the loss.
How do I plan for a profit target?
Add the target profit to fixed costs and divide as usual.
