Break-Even Point Calculator

It is the minimum number of units you must sell to cover all fixed and variable costs with zero profit or loss. Every unit sold beyond this point contributes its full contribution margin directly to profit.

The contribution margin is the selling price minus the variable cost per unit. It represents what each sale contributes toward covering fixed costs. Once total contributions equal fixed costs, you have reached break-even. After that, each additional unit sold generates contribution margin as profit.

There are three levers: raise the selling price, lower variable cost per unit, or reduce fixed costs. Raising price is often the fastest and most powerful lever because it increases contribution margin directly. Cutting variable costs through better sourcing or efficiency achieves the same effect. Reducing fixed overhead such as rent or salaries also helps but typically takes longer to implement.

The margin of safety is the difference between your expected sales and your break-even sales, expressed as a percentage of expected sales. It tells you how far sales can fall before you start losing money. A 30 percent margin of safety means sales could drop by nearly a third before the business is unprofitable, giving you a cushion against unexpected downturns.
