About this break even calculator

A break-even calculator tells you the sales volume where profit is zero — critical for startups and pricing decisions.

How to use

  1. Enter fixed costs, variable cost per unit, and selling price.
  2. Read break-even units and revenue.

Formula

Break-even units = Fixed costs ÷ (Price − Variable cost)

Worked examples

Example: Fixed $10,000, variable $12, price $25 → contribution $13 → break-even ≈ 769.23 units.

Tips

  • If price ≤ variable cost, you cannot break even by selling more.

Frequently asked questions

What are fixed vs variable costs?

Fixed costs stay roughly the same (rent, salaries). Variable costs rise with each unit (materials, shipping).
