Quick answer
Markup = Margin ÷ (1 − Margin) and Margin = Markup ÷ (1 + Markup), using decimals. A 40% margin equals a 66.67% markup; a 50% markup equals a 33.33% margin.
Conversion formulas
Markup % = Margin % ÷ (100 − Margin %) × 100
Margin % = Markup % ÷ (100 + Markup %) × 100
Examples
- 25% margin → markup: 25 ÷ 75 × 100 = 33.33%
- 60% markup → margin: 60 ÷ 160 × 100 = 37.5%

Why converting matters
Suppliers, sales teams and spreadsheets often speak different "languages". A buyer may be told to keep a 35% margin while the pricing sheet applies a markup. If the sheet adds 35% to cost, the real margin is only 25.93% — nearly ten points short. Converting first avoids that gap. For full pricing with a dollar cost, use the markup calculator or the profit margin calculator.

Frequently asked questions
How do you convert margin to markup?
Divide the margin by (1 − margin), using decimals. A 30% margin is 0.30 ÷ 0.70 = 0.4286, or a 42.86% markup.
How do you convert markup to margin?
Divide the markup by (1 + markup), using decimals. A 100% markup is 1 ÷ 2 = 0.5, or a 50% margin.
What markup gives a 50% margin?
A 100% markup — selling at double the cost — gives exactly a 50% profit margin.
Why is markup always higher than margin?
Both use the same profit, but markup divides it by cost and margin divides it by price. Price is larger than cost on a profitable sale, so the margin figure is always smaller.
