Convert markup percentage into profit margin before you set a selling price
Formula: Margin % = Markup % ÷ (100 + Markup %) × 100. Markup uses cost as the base; margin uses selling price as the base.

Use this converter when you know the markup on cost but need to understand the real profit margin on selling price. Enter a markup percentage, plus an optional cost example, to convert markup into margin and see the matching selling price and profit. It is useful for retailers, ecommerce sellers, Amazon sellers, Etsy shops, wholesalers, and small businesses comparing keystone pricing, supplier cost, product pricing, and target margin. The page is intentionally narrow: it answers the common pricing question, 'What margin does this markup actually give me?' Use it before sharing wholesale terms, setting a retail price, checking a marketplace listing, or explaining why a 50% markup does not leave a 50% margin after the sale.
A 50% markup means the selling price is 1.5x cost. On a $100 cost example, price is $150 and profit margin is 33.3%.
A 100% markup doubles cost. On a $20 cost example, price is $40, profit is $20, and equivalent margin is 50%.

Markup and margin use different bases. Markup is calculated from cost, while margin is calculated from selling price. These steps help you convert one number into the other without mixing the two, then decide whether the resulting margin is strong enough for fees, discounts, returns, and shipping. Keep this page for percentage conversion; use a full pricing calculator when you need to include channel fees or ad costs.
Start with the markup you plan to add on top of cost. For example, a 50% markup means the selling price is cost plus half of cost again. This is common in cost-plus pricing, wholesale quotes, and quick retail pricing, but the percentage does not represent profit as a share of the final sale price.
The conversion works from percentage alone, but adding a cost example makes the result easier to understand. Use landed cost, product cost, or a simple $100 example. For ecommerce sellers, landed cost is usually better than supplier cost because freight, packaging, and prep can change the real price floor.
The calculator converts markup to margin using the formula Margin % = Markup % ÷ (100 + Markup %) × 100. A 50% markup equals a 33.3% margin, while a 100% markup equals a 50% margin. This gap matters because margin is the number most sellers use to judge profitability.
Use the price and profit example to see what the percentage means in dollars. This helps avoid confusing a high markup with the same high profit margin. If the dollar profit looks too small after marketplace fees, ad spend, or shipping, move to a full selling price or profit calculator before publishing the price.
If the converted margin is lower than your target, use the Selling Price Calculator to work backward from the margin you need instead of guessing a markup. This is especially helpful when you know the business needs a 30% margin but a supplier, retailer, or spreadsheet is talking in markup terms.
Use this formula: Margin % = Markup % ÷ (100 + Markup %) × 100. For example, 50% markup becomes 50 ÷ 150 × 100 = 33.3% margin. The formula works because markup compares profit to cost, while margin compares the same profit to the final selling price.
No. Markup is based on cost, while margin is based on selling price. A product with $100 cost and 50% markup sells for $150 and has $50 profit, but the margin is 33.3%, not 50%. Mixing them up can cause sellers to overestimate profit before fees and discounts.
A 100% markup equals a 50% margin. If cost is $20, a 100% markup creates a $40 selling price and $20 profit. That $20 profit is half of the $40 selling price. This is why keystone pricing doubles cost but does not produce a 100% profit margin.
Use markup when you build a price from cost. Use margin when you want to measure how much of the final sale price remains as profit. Ecommerce sellers usually need both because fees, shipping, discounts, returns, and ads reduce the final margin. Markup is useful for quick pricing; margin is better for profitability decisions.
Because markup divides profit by cost, but margin divides profit by selling price. Selling price is always larger than cost when there is profit, so the margin percentage is lower than the markup percentage. The higher the markup, the larger the dollar profit, but the margin still uses the final sale price as its base.
