Break-Even & Contribution Margin Analyzer

Three numbers, price, variable cost, and fixed cost, are enough to know exactly how many units stand between you and your first dollar of profit.

How To Use This Calculator

Enter your selling price and variable cost per unit, your fixed costs, and what you actually expect to sell.

Every unit above break-even drops its full contribution margin straight to profit, which is why operating leverage cuts both ways: a small change in volume swings profit by a lot more once fixed costs are covered. The chart shows exactly where revenue crosses total cost.

Your Inputs

Selling Price Per Unit $50.00

Variable Cost Per Unit $30.00

Total Fixed Costs $50,000

Expected Unit Sales 3,500

Assumes a single product (or a constant sales mix across products), and that variable cost per unit and price stay constant across the volumes shown, no quantity discounts or step-fixed costs.

Total Revenue Total Cost

Operating leverage here is measured at your expected sales level specifically, it changes at every volume, highest just above break-even and lower as sales climb well past it.
