What Is Break-Even Analysis?

A break-even analysis identifies the exact point where total revenue equals total costs — the moment your business neither gains nor loses money. Every unit sold beyond the break-even point generates pure profit. This break-even calculator helps entrepreneurs, managers, and analysts understand the minimum sales volume required for profitability.

The Break-Even Formula

BEP (units) = Fixed Costs ÷ Contribution Margin. Where Contribution Margin = Price Per Unit − Variable Cost Per Unit. BEP (revenue) = Fixed Costs ÷ Contribution Margin Ratio. These formulas are foundational in cost-volume-profit (CVP) analysis used in managerial accounting.

Understanding Your Results

The break-even units tell you the minimum quantity to sell each period to cover all costs. The contribution margin ratio shows what percentage of each revenue dollar flows toward fixed costs and ultimately profit. Margin of safety indicates how far above break-even your target sales are.

Key Inputs and Benchmarks

Fixed costs include rent, salaries, insurance, and depreciation — costs that don't change with production volume. Variable costs change directly with output: raw materials, direct labor, shipping. Selling price should reflect market positioning and target margin. Most businesses aim for 20–40% contribution margin ratios in manufacturing, 50–80% in services.

Using Break-Even in Business Planning

Use BEP when launching a new product to validate pricing. Compare BEP scenarios across different price points. Calculate how many customers or subscriptions you need before becoming profitable. Investors often ask founders about break-even timelines during due diligence.
