Units needed for revenue to cover fixed and variable costs, with nothing left over.
How to calculate a break-even point
Enter fixed costs, price per unit, and variable cost per unit to see how many units — and how much revenue — you need to cover your costs.
How it's calculated
Each unit sold contributes its price minus its variable cost toward fixed costs. Dividing fixed costs by that contribution margin gives the number of units needed to break even.
Good to know
- The result is rounded up to a whole unit, since a fraction of a unit can't actually be sold.
- If price doesn't exceed variable cost, no number of units would ever break even.
Worked example
With $10,000 in fixed costs, a $50 price, and a $30 variable cost per unit, the $20 contribution margin means 500 units (500 × $20 = $10,000) covers the fixed costs exactly.

FAQ
What happens if my price is lower than my variable cost?
Every unit sold loses money, so there's no break-even point — the calculator shows an invalid result in that case.
Does this include fixed costs I haven't listed?
No — only the fixed costs total you enter is used. Include rent, salaries, and other recurring costs in that single figure.
Does the break-even point change if my fixed costs change?
Yes — higher fixed costs raise the number of units needed to break even, since more contribution margin is required to cover them.
