About
Work out how many units you need to sell before a product or offer becomes profitable.
What this calculator does
The Break Even Calculator shows how many units you need to sell to recover your fixed costs, how much contribution margin each sale creates, and how much revenue that break-even point represents.
How the calculation works
First, the calculator subtracts variable cost per unit from selling price per unit to find contribution margin. Then it divides fixed costs by that margin to estimate the exact break-even unit count. Because businesses usually sell whole units, it also rounds the result up to the next full sale.
Why target profit matters
If you enter a target profit, the calculator extends the same logic beyond break-even. This helps you plan the unit count and revenue needed not only to cover costs, but also to reach a chosen profit goal for a launch, campaign, or product line.
Who can use it
- Freelancers pricing services or retainers.
- Online shops evaluating a product margin.
- Restaurants, cafes, and local businesses testing menu or offer pricing.
- Founders building simple sales targets for a launch.
Important limitations
This calculator assumes one average selling price and one average variable cost per unit. If your mix changes by season, discount level, or channel fees, treat the result as a planning estimate and recalculate with updated assumptions when your cost structure changes.
