About the Break-Even Calculator
Every business owner needs to know one number before anything else: how much they must sell just to cover their costs. Below the break-even point you are losing money; above it, you are finally making a profit.
This Break-Even Calculator finds the number of units you must sell to cover your fixed and variable costs, using your price per unit. It is an essential sanity check before launching a product or setting a price.
How to use the Break-Even Calculator
- Enter your fixed costs.
- Enter the variable cost per unit.
- Add your selling price per unit.
- See the break-even point in units and revenue.
Key features of the Break-Even Calculator

How the Break-Even Calculator works
This calculator uses the established mathematical formulas that banks, lenders and financial institutions rely on — for interest, amortization, EMI, compounding, tax and investment growth. Where local rules apply (such as tax bands or GST/VAT rates), the tool follows the relevant published structure, and figures can be expressed in the currency you work in.
Every calculation runs in your browser, so the financial figures you enter stay completely private.
Tips & best practices
- The gap between your price and variable cost per unit — the contribution margin — is what pays down your fixed costs, so protect it.
- Lowering fixed costs or raising the contribution margin both reduce how many units you must sell to break even.
- Run a worst-case scenario with higher costs before committing, so you know your margin of safety.
Standards & accuracy
Uses the same standard financial formulas as banks and lenders, with support for multiple currencies and international tax rules.
