Plain definition
Break-even sales expresses the break-even point in revenue rather than units. In a stable single-margin model it equals fixed costs divided by contribution margin ratio, where the ratio is contribution divided by sales. It is useful where products are priced differently or management plans in revenue, but it is only as sound as the margin assumption beneath it.
Revenue is not enough by itself. A sales target can cover fixed cost under a 60% contribution margin and fail under a 30% margin.
Illustrative example
Monetary examples use Saudi riyals (SAR). The same principles apply in other currencies.
Suppose fixed costs are and each of sales contributes after variable cost. The contribution margin ratio is 40%, so break-even sales are : 60,000 ÷ 40%. A discount that reduces the ratio changes the required sales before it changes the headline revenue target.
This gives sales leaders a mechanism: improve price, mix, or variable cost—or accept that more revenue is required.
| Fixed costs | |
|---|---|
| Contribution margin ratio | |
| Break-even sales |
Use a weighted margin when products have different margins; do not apply one product’s ratio to all revenue.
Why it matters
It stops revenue targets from being treated as profit targets without showing the economic conversion between them.
Practical consequence
Calculate the margin ratio from current pricing and variable costs, state the expected sales mix, and reconcile it with unit break-even. Recalculate when a promotion or cost change affects margin. Pair the sales target with collection timing and capacity so a revenue threshold does not conceal a cash need.
