The core formula

Break-even happens when contribution profit covers fixed costs.

Break-even units Fixed costs ÷ (selling price − variable cost)

For a revenue-only calculation, divide fixed costs by the gross margin percentage expressed as a decimal.

Use the result

Three numbers to watch after calculating

Contribution margin

The amount each sale contributes toward fixed costs and profit after direct variable costs.

Break-even revenue

The minimum sales revenue needed before the business begins producing operating profit.

Margin of safety

The distance between expected sales and break-even. A larger cushion generally means less operating risk.
