Margin vs Markup Converter
Margin and markup measure the same profit on different bases, and swapping them is the most common pricing mistake. This converter turns a profit margin into the equivalent markup (and back) and, if you enter the cost, also shows the selling price. A 40% margin is a 66.67% markup, not 40%.
Margin is measured on the selling price; markup is measured on the cost. That is why a 40% margin is a 66.67% markup, not 40%. Enter a cost (optional) to see the selling price. Use amounts excluding VAT.
How the result is worked out
| Profit margin (on the price) | 40% |
| Markup (on the cost) | 66.67% |
Educational estimate, not financial advice. It converts between a product’s margin and markup; it does not include the business’s overheads (rent, salaries, taxes) or VAT.
Margin and markup are different bases
Profit margin measures the profit as a percentage of the selling price (margin = profit ÷ price); markup measures the same profit as a percentage of the cost (markup = profit ÷ cost). Because the price is always higher than the cost, the markup is always larger than the margin. That is why “working at 40%” means different prices depending on whether you mean margin or markup.
From margin to markup
To turn a margin into the equivalent markup, divide the margin by (1 − margin): markup = margin ÷ (1 − margin). A 40% margin gives 0.40 ÷ 0.60 = a 66.67% markup. The higher the margin, the bigger the gap: a 50% margin is already a 100% markup.
From markup to margin
The other way round, divide the markup by (1 + markup): margin = markup ÷ (1 + markup). A 100% markup is 100 ÷ 200 = a 50% margin; a 50% markup is a 33.33% margin. The margin is always smaller than the markup, and never reaches 100%.
From cost to selling price
If you enter the product cost, the converter also shows the selling price and the profit per unit: price = cost × (1 + markup), the same as cost ÷ (1 − margin). With a €60 cost and a 40% margin (66.67% markup), the price is €100 and the profit €40. Leave the cost at zero for a percentage-only conversion.
Worked example
A shop wants a 40% margin. As a markup, that is 0.40 ÷ (1 − 0.40) = 0.40 ÷ 0.60 = 66.67%. If it applied a 40% markup to the cost (instead of 66.67%), it would end up with a margin of only 28.6%, well below what it wanted. On an item costing €60 excluding VAT, a 40% margin gives a €100 price (€40 profit); a 40% markup would give only €84.
