Break-Even Calculator

The break-even point is the level of sales at which a business's total revenue equals its total costs, producing neither profit nor loss. Below it, the business loses money; above it, each additional sale contributes to profit. Break-even analysis is one of the most fundamental tools in business planning because it translates costs and pricing into a clear, concrete sales target.

The analysis rests on separating costs into two types. Fixed costs stay the same regardless of how much you produce or sell — rent, salaries, insurance, equipment leases. Variable costs change directly with output — raw materials, packaging, per-unit labor, payment processing fees. The distinction matters because fixed costs must be covered no matter what, while variable costs rise with each unit sold.

The bridge between them is the contribution margin: the price per unit minus the variable cost per unit. This is the amount each sale "contributes" toward covering fixed costs and, eventually, generating profit. Dividing total fixed costs by the contribution margin gives the break-even point in units — the exact number you must sell before you start making money. Multiplying that by the price gives break-even revenue.

Break-even analysis drives several important decisions. In pricing, it shows how a higher or lower price changes the sales target: raising the price increases the contribution margin and lowers the units needed, while discounting does the opposite. In planning, it sets a realistic sales goal and tests whether a venture is viable — if the break-even volume far exceeds what the market could plausibly buy, the idea may need rethinking. It also reveals the margin of safety: how far current or projected sales sit above break-even, indicating how much of a sales drop the business could absorb before slipping into a loss.

The model does make simplifying assumptions — that price and variable cost per unit are constant, and that costs split cleanly into fixed and variable — so real-world results vary. Even so, break-even analysis offers a powerful, quick gut-check for any product or business. Knowing your number focuses pricing, cost control and sales targets around the single threshold that separates loss from profit.
