About this calculator

Break-even is the sales volume at which total revenue exactly covers total costs. Every unit sold beyond that point adds contribution margin directly to profit.

Worked example

calculated with the default values below

Fixed costs 10,000 $ · Selling price per unit 25 $ · Variable cost per unit 10 $ Break-even units 667 · Break-even revenue 16,675.00 $ · Contribution margin per unit 15.00 $

Formula and variables

Q = ceil(F/(P − V)); R = Q·P

F
Fixed costs
P
Unit selling price
V
Variable cost per unit
Q
Break-even units
R
Revenue at break-even

Break-even requires P − V > 0. Whole units are rounded up so revenue covers fixed costs; when contribution is zero or negative, no finite break-even quantity exists.

Frequently asked questions

Why does the result round break-even units up?

Fixed costs divided by contribution per unit can produce a fraction, but you cannot sell a fraction of a unit. The calculator rounds the required quantity up to the next whole unit and reports the revenue at that quantity. If price is equal to or below variable cost, each sale makes no positive contribution, so there is no finite break-even quantity; the result is shown as a dash.
