Break-even calculator — units and revenue needed
Work out how many units you need to sell to cover your costs, what revenue that represents, and how many more it takes to hit a target profit.

Rent, salaries, tooling — costs that do not change with volume.
Materials, shipping, payment fees.

A single-product model. It assumes fixed costs stay fixed and that every unit sells at the same price — real businesses have step costs, discounts and product mix.
How to use
- Enter your fixed costs. Rent, salaries, software — anything that does not change with volume.
- Enter price and variable cost per unit. Variable costs are materials, shipping and payment fees.
- Read the break-even point. In units and in revenue.
- Add a target profit. To see the units needed to actually make money, not just survive.
Questions
How is break-even calculated?
Fixed costs divided by the contribution per unit, where contribution is price minus variable cost. €10,000 fixed, €25 price, €15 variable: €10,000 ÷ €10 = 1,000 units.
What is contribution margin?
The share of each sale left after variable costs, available to cover fixed costs. At €25 price and €15 variable cost it is €10, or 40%. The higher it is, the fewer units you need.
What if my variable cost exceeds my price?
Then you lose money on every sale and never break even — volume makes it worse, not better. The tool says so rather than returning a nonsense number.
What does this model miss?
It assumes one product, one price and genuinely fixed fixed-costs. Real businesses have discounts, product mix, and step costs that jump when you add a shift or a warehouse.
