Units to break even

Revenue at break-even$25,000.00

Contribution margin (unit)$20.00

Contribution margin (%)40%

Above this number of sales you turn a profit; below it, a loss.

How the calculation works

Contribution margin is price − variable cost. The break-even point is fixed costs ÷ contribution margin — the number of units that brings the result to zero.

Frequently asked questions
