Markup & Margin Calculator

About this calculator

This calculator converts a markup percentage into selling price, profit, and profit margin, clarifying a distinction that trips up a lot of business owners: markup is profit expressed as a percentage of cost (price = cost × (1 + markup%)), while margin is that same profit expressed as a percentage of the selling price (margin% = profit ÷ price × 100). Because the two use different denominators, the same dollar profit produces a markup percentage that's always higher than the margin percentage — a 100% markup, for example, corresponds to only a 50% margin.

Retailers and small business owners use it to set prices that hit a target margin rather than guessing from markup alone; accountants and bookkeepers use it to reconcile pricing sheets with profitability reports; and e-commerce sellers use it to price products consistently across a catalog while protecting margin against fees and discounts. Enter a unit cost and either a markup or margin percentage to get the full breakdown.
