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
- Enter fixed costs, variable cost per unit, and selling price.
- 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?
