What is a Break-Even Calculator?
A break-even calculator helps entrepreneurs and business owners determine the exact point at which total revenue equals total costs — producing neither profit nor loss. Knowing your break-even point is one of the most fundamental steps in validating a business model, setting prices, and planning production volumes. It answers the critical question: "How many units do I need to sell before I start making money?"
This tool uses the standard break-even formula: Break-Even Units = Fixed Costs ÷ (Selling Price − Variable Cost per Unit). The denominator — selling price minus variable cost — is called the contribution margin per unit. All calculations happen instantly in your browser; no data is sent to any server.
How to Use
- Enter your total Fixed Costs — costs that don't change regardless of sales volume (rent, salaries, software subscriptions).
- Enter the Variable Cost per Unit — what it costs you to produce or deliver each individual unit (materials, shipping, commissions).
- Enter the Selling Price per Unit — the price you charge customers for each unit.
