Operating Leverage Break-Even Calculator

About this calculator

Break-even units are fixed costs ÷ (unit price − variable cost per unit), where the denominator is the contribution margin per unit — the amount each sale contributes toward covering fixed costs after variable costs are paid. Break-even revenue is simply break-even units × unit price.

Business owners, financial analysts, and startup founders use this to find the minimum sales volume needed to cover fixed costs like rent, salaries, and equipment before turning a profit, and to see how sensitive that break-even point is to pricing changes — a business with high fixed costs and thin margins (high operating leverage) needs a much larger volume swing to break even than one with low fixed costs and fat margins.
