Enter a cost and a markup percentage to instantly see the selling price, your profit, and the true profit margin (which is not the same as the markup).
Results update as you type. Markup is profit over cost; margin is profit over selling price.
Multiply the cost by one plus the markup percentage divided by 100: selling price = cost × (1 + markup ÷ 100). For example, an $80 item with a 25% markup sells for 80 × 1.25 = $100.
Markup is the profit as a percentage of cost, while margin is the profit as a percentage of the selling price. An item costing $80 sold for $100 has a 25% markup but a 20% margin, because $20 profit is 25% of the $80 cost but only 20% of the $100 price.
Divide profit by the selling price and multiply by 100: margin = (price − cost) ÷ price × 100. The selling price must be greater than zero.
