How to calculate break-even point

The break-even point is the sales level where total revenue covers total costs. At this point, the business is not making a profit or a loss. To calculate it, you need fixed costs, selling price per unit, and variable cost per unit.

Calculate contribution per unit

Selling price per unit
Variable cost per unit
Contribution per unit

Contribution per unit = Selling price per unit − Variable cost per unit

Contribution per unit shows how much each sale contributes toward covering fixed costs after variable costs are paid.

Calculate contribution margin ratio

Contribution per unit
Selling price per unit
Contribution margin ratio

Contribution margin ratio = Contribution per unit ÷ Selling price per unit

Contribution margin ratio shows the percentage of each sale that contributes to fixed costs and profit.

Calculate break-even units

Fixed costs
Contribution per unit
Break-even units

Break-even units = Fixed costs ÷ Contribution per unit

Break-even units show how many units you need to sell to cover your fixed costs.

Calculate break-even revenue

Contribution margin ratio
Break-even revenue

Break-even revenue = Fixed costs ÷ Contribution margin ratio

Break-even revenue shows the total sales amount needed to cover all costs.

Recalculate break-even when prices, supplier costs, salaries, or operating costs change.
Use break-even revenue to set sales targets.
