Margin = profit ÷ selling price — the percentage of the sale price that's profit.
Markup = profit ÷ cost price — the percentage added on top of cost to set the price. Margin and markup are always different numbers for the same sale (e.g. a 50% markup is only a 33% margin).
100% in-browser — all math runs locally, no data leaves your device.
Profit Margin & Markup Calculator computes margin percentage and markup percentage from a cost price and selling price, or works backward to suggest the selling price needed to hit a target profit margin — clarifying the common confusion between margin (profit ÷ price) and markup (profit ÷ cost), which are always different numbers for the same sale.
Choose a calculation mode
Cost + price → margin, cost + price → markup, or cost + target margin → suggested price.
