How the calculation works

Break-even units equal fixed costs divided by contribution per unit. A target profit is added to fixed costs before using the same calculation.

Evaluate a product launch, event, small business offer or paid campaign before committing fixed expenses.

Important financial information

This calculator provides an educational estimate from the values you enter. It does not use live prices, predict returns or provide investment, tax or legal advice. Verify exchange rules, fees, rates and product terms before making a financial decision.

Private, fast and mobile-ready

The workspace runs with browser JavaScript and does not submit entered values to a Rantey calculation endpoint. Controls use readable labels, large touch targets and responsive result panels for narrow screens.
