What makes this tool more useful

Avoid confusing markup with margin. Enter cost and price to compare both percentages, then include volume and fixed costs for an operating estimate.

How the calculation works

Margin divides profit by selling price, while markup divides profit by cost. The tool presents both formulas beside the same inputs.

Price products, services or marketplace listings with clearer profit assumptions.

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.
