About Break-Even Point Calculator

The break-even point calculator tells you how many units you must sell before a product stops losing money. Enter your fixed costs — rent, salaries and other expenses that do not change with volume — plus the selling price per unit and the variable cost per unit.

The math rests on the contribution margin: selling price minus variable cost, the amount each sale contributes toward fixed costs. Break-even units equal fixed costs divided by that margin, rounded up to a whole unit, and break-even revenue is those units at the selling price. The margin is also shown as a percentage of price.

It is a core check when pricing a product, writing a business plan or evaluating whether a side project can cover its overhead. The calculator is free and runs live in your browser.

How to use Break-Even Point Calculator

  1. Enter your total fixed costs for the period.
  2. Set the selling price per unit.
  3. Enter the variable cost per unit (materials, shipping, transaction fees).
  4. Read the break-even units, break-even revenue and contribution margin per unit and in percent.

Frequently asked questions

Selling price minus variable cost per unit — the slice of each sale left over to cover fixed costs. Once fixed costs are covered, that same margin becomes profit on every additional unit.

You cannot sell a fraction of a unit, and stopping just below the exact figure still leaves a small loss. Rounding up guarantees the reported quantity fully covers fixed costs.

Fixed costs stay the same regardless of volume: rent, salaries, insurance, software. Variable costs scale with each unit sold: materials, packaging, shipping, payment fees. Classify honestly — it drives the whole result.

Three levers: cut fixed costs, raise the price, or reduce the variable cost per unit. Adjust each input in the calculator to see which moves your break-even the most.

Then every sale loses money and no volume can reach break-even — the contribution margin is negative. You would need to reprice or cut unit costs before volume helps.
