Behind the answer

Break-even units = ceil(fixed costs ÷ (price − variable cost))

How to use this calculator

Find break-even units, units for a profit target, profit at a volume, or required price at a target volume. Contribution is price minus variable cost. Indivisible required units round upward.

Enter find, fixed costs, variable cost per unit and review the remaining options.
Select Calculate or change a value to update the result. Read the result label and units before copying.

Formula and method

Break-even units = ceil(fixed costs ÷ (price − variable cost))

Price must exceed variable cost. Assumes constant price, unit cost, and fixed costs within the modeled range.

Worked example

10,000 fixed costs and 20 contribution per unit require 500 units.

Questions about break-even calculator

What if the price does not cover variable cost?

No positive contribution remains to cover fixed costs, so the tool rejects a price at or below variable cost. With fixed cost 10,000 and contribution 20 per unit, 500 whole units are needed to break even.

What assumptions should I check?

Price must exceed variable cost. Assumes constant price, unit cost, and fixed costs within the modeled range.
