Frequently asked questions
What's the difference between markup and margin?
Markup is profit as a percentage of cost; margin is profit as a percentage of the selling price. On a $10 item sold for $15, the $5 profit is a 50% markup (5/10) but a 33.3% margin (5/15). Same profit, different base.
How do I convert markup to margin?
Margin equals markup divided by one plus the markup. A 50% markup is 0.5 / 1.5 = 33.3% margin; a 100% markup is 0.5, or 50% margin. To go the other way, markup equals margin divided by one minus margin.
Why does the difference matter?
Setting prices from markup but reporting or targeting margin without converting leads to underpricing. Retailers routinely mark up by a percentage but their accounting speaks in margin, so mixing them up quietly erodes profit. This converter keeps the two straight.
About this tool
The markup to margin converter turns a markup percentage into the equivalent gross margin and vice versa. They describe the same profit from different bases: markup is profit as a percentage of cost, margin is profit as a percentage of the selling price. Because price is always larger than cost, the margin is always the smaller number — a 50% markup is a 33.3% margin. Edit either field to convert, with a quick-reference table of common markups. Everything is calculated in your browser.
