About the Break-Even Calculator
Break-even is the sales quantity needed to cover a fixed cost using profit contribution from each unit sold.
Formula or method
Contribution per unit = price − variable cost. Break-even units = ceiling(fixed costs ÷ contribution per unit), provided contribution is positive.
Worked example
A product priced at 50 with a variable cost of 30 contributes 20 per sale. With 1,000 of fixed expenses, the modeled break-even point is 50 units.
How to use the tool
Start with the example values above, then replace each input with your own figures. The results update immediately. Review the units, denominators, and assumptions before using any number in an important decision.
Assumptions and limitations
If contribution is zero or negative and fixed costs are positive, no quantity achieves break-even. Taxes, changing prices, capacity limits and cash-flow timing are outside this simplified model.
Frequently asked questions
Why does the calculator round up?
You cannot usually sell a fraction of a physical item. The smallest whole quantity that covers fixed costs is the practical break-even unit count.
