25% Margin to Markup: a 25% margin needs a 33.3% markup

The formula
25 ÷ 75 × 100 = 33.3%
price = cost ÷ (1 − 25/100) = cost ÷ 0.75
The conversion is markup = margin ÷ (100 − margin). For 25% that is 25 ÷ 75 = 33.3%. As the target margin rises the denominator shrinks, which is why high margins need markups that look extreme when quoted on cost.

Margins near 25%
Between 15% and 35% margin the markup needed runs from 17.6% to 53.8%: it climbs faster than the margin because the cost share of the price keeps shrinking. The multiplier column turns a cost list into prices at that margin in one step.
Worked example
Numbers: cost $199.00, margin 25%, markup 33.3%, price $265.33, profit $66.33. The same $66.33 is a small share of $265.33 and a larger share of $199.00; that is the whole difference between the two percentages.
The margin-as-markup trap
Marketplaces and retailers state their requirements as margin. A buyer who needs "25% margin" will not accept a 25% markup: at 25% markup they keep 20%, 5 points less than agreed.
When a margin target is the right tool
Set prices from a margin target when the business is judged on gross margin: an online store, a wholesaler with published margin bands, or any company preparing accounts for a lender. A 25% margin target converts to a 33.3% markup for the person entering prices.
Coming from the other direction: a 25% markup, the number people often type by mistake, produces only a 20% margin. The 25% margin on this page needs the full 33.3% markup.
