Break-Even Units Calculator
Used by developers, writers, and creators worldwide.
A break-even units calculator tells you how many units you must sell before a product starts making a profit. Enter your fixed costs, the price you charge per unit, and the variable cost to produce each unit, and it computes the contribution margin per unit, then divides your fixed costs by that margin to find the break-even quantity and the revenue it represents. Below that number you lose money; above it, every sale adds profit equal to the margin. Founders, product managers, and small business owners use it to test whether a price is viable, set sales targets, and understand the cost structure behind a product. If the price does not cover the variable cost, the tool flags that you can never break even. Use it to pressure-test a business idea, compare pricing options, or set the minimum volume your plan must reach.

FAQ
what is the contribution margin
It is the price per unit minus the variable cost per unit — the amount each sale contributes toward covering fixed costs. Once total contribution equals fixed costs, you break even, and every further unit becomes profit.
what if the price is below the variable cost
Then the contribution margin is zero or negative and you lose money on every unit, so no sales volume can reach break-even. The tool detects this and tells you to raise the price above the variable cost.
is this financial advice
No. This is a simplified planning estimate based on the costs you enter and assumes they stay constant. Real businesses face stepped and mixed costs. It is not financial advice — consult a qualified professional.
