Calculate selling price from cost and a target markup or margin, with both percentages shown.
Your inputs stay on your device. All calculations run in your browser without uploading, storing or tracking the numbers you enter. Clear formulas and visible assumptions let you review the estimate.
Markup: price = cost × (1 + rate/100). Margin: price = cost / (1 − rate/100).
Cost must be positive. Target margin must be below 100%; markup may exceed 100%. Taxes and additional selling expenses are excluded.
Decimal arithmetic uses exact fractions. Currency displays round to two decimals; exact unrounded values are included where relevant. Date calculations use whole Gregorian calendar days. Results are estimates under the stated assumptions.
No. Inputs are processed locally and not persisted. Only the theme preference is stored. Copy and report downloads happen when you choose them.
