Break-Even Calculator
Find how many units you must sell to cover fixed and variable costs.
Every business plan eventually faces the same question: how much do we need to sell before we stop losing money? The break-even point is where total revenue equals total costs — below it every sale still leaves a deficit, above it each sale contributes profit.
This calculator takes your fixed costs (rent, salaries, tooling), your selling price per unit, and your variable cost per unit (materials, shipping, transaction fees), and returns the break-even point in both units and revenue. The gap between price and variable cost — the contribution margin — is what chips away at fixed costs with every sale, and seeing it explicitly often reshapes pricing decisions.
