How the business break-even calculator works
Calculate the units and revenue needed to cover fixed costs or reach a target profit.
Required units = (fixed costs + target profit) ÷ (price − variable cost), rounded up.
Read our calculation methodology and limitations.
Example
With $25,000 fixed costs and $60 contribution per unit, break-even requires 417 whole-unit sales.
What affects the result
- Price must exceed variable cost.
- Results assume constant unit economics.
- Product mix, capacity, tax, and cash timing can change real outcomes.
Frequently asked questions
Why are units rounded up?
A fraction of a unit normally cannot be sold, so the threshold rounds up to the first whole unit that covers the goal.
What belongs in fixed costs?
Include costs that do not change with each unit over the period, such as base rent, salaries, and software commitments.
