Margin is the percentage of your selling price that you keep as profit.
Selling price = cost ÷ (1 − margin ÷ 100)

SAME PROFIT. A DIFFERENT PERSPECTIVE.
They sound similar. They tell different stories.
Here’s what happens with a $100 cost.
Margin is the percentage of your selling price that you keep as profit.
Selling price = cost ÷ (1 − margin ÷ 100)
Markup is the percentage you add to your cost to arrive at a selling price.
Selling price = cost × (1 + markup ÷ 100)
Subtract cost from selling price: profit = selling price − cost. A $135 selling price and $100 cost give $35 profit.
Markup (%) = margin ÷ (100 − margin) × 100. A 35% margin is approximately 53.85% markup.
Margin (%) = markup ÷ (100 + markup) × 100. A 35% markup is approximately 25.93% margin.
A 35% margin needs a higher selling price than a 35% markup. The calculator shows you both.

A real app screen. The same $100 example.

A FEW USEFUL ANSWERS
More understanding.
Better pricing decisions.
Yes. Use the website calculator without an account or subscription. The site is designed to be supported by advertising; adverts are disabled on this version of the site.
Use margin when your target profit is a percentage of the selling price. Use markup when you want to add a percentage to your cost. The calculator always shows the equivalent percentage so you can compare them.
No. AUD, USD, GBP, EUR, NZD, CAD, JPY and SGD change labels and display rounding only. There are no live exchange rates. JPY displays whole amounts; the other currencies display two decimal places.
No. The calculator estimates selling price and profit from your entered cost and percentage. It does not add tax, fees or discounts. It models non-negative profit; margin must be below 100%.
Your calculations run in your browser. Figures are not saved across visits or sent to an advertising or analytics service. Read our privacy information for this version of the site.
Markup measures profit relative to cost, so it is undefined when cost is zero and the percentage is positive. Enter a cost above zero, or enter zero for both cost and percentage.
