How the Margin to Markup Converter works
Suppliers quote markup, accountants report margin, and the two numbers never match. This converts between them in either direction so a supplier's quote and your target margin can be compared without arithmetic errors in between.

Frequently asked questions
How do I convert margin to markup?
Markup = margin ÷ (1 − margin), with margin as a decimal. A 30% margin: 0.30 ÷ 0.70 = 42.9% markup.
How do I convert markup to margin?
Margin = markup ÷ (1 + markup). A 100% markup — doubling the cost — is a 50% margin, which is the conversion most people already know intuitively even if they have not seen the formula.
Can margin ever exceed 100%?
No. Margin is a share of the selling price, so it approaches 100% but cannot reach it — that would mean the goods cost nothing. Markup has no ceiling: a £1 item sold for £100 is a 9,900% markup.
Why do industries differ on which they quote?
Retail and wholesale grew up quoting markup because it applies directly to a known cost. Finance and accounting use margin because it is comparable across companies with different cost structures. Neither is wrong; mixing them is.
