Markup & Margin Calculator — Cost, Price, Markup % and Margin %

Real-world use cases

• Price a retail product from a supplier markup

  Your supplier quotes goods at $12 a unit and your store's policy is a standard 60% markup. Enter cost 12 and markup 60 — the shelf price comes back at $19.20, with the margin shown right beside it at 37.5%. That second number is what you report to your accountant and what you compare against the rent-and-payroll line. Reading both at once stops the most common retail mistake: assuming a 60% markup means you keep 60 cents on the dollar, when you actually keep 37.5.

• Hit a target margin in an e-commerce listing

  Marketplace fees and ads mean you need at least a 35% margin to stay profitable, and the market won't bear more than $29.99 for the item. Switch to Price + Margin %, enter 29.99 and 35, and the tool tells you the most you can pay for stock: about $19.49. Now you have a hard ceiling to take into your next supplier negotiation instead of guessing and discovering the loss after the quarter closes.

• Set wholesale tiers that protect your floor

  You sell direct at a 50% margin but want a wholesale price that still leaves a 20% margin for you. Enter your cost in Cost + Margin %, read the retail price, then re-run with margin 20 to get the wholesale price. Sharing the URL with a buyer sends them the exact scenario, so the negotiation starts from the same numbers rather than two spreadsheets that disagree by a rounding error.

• Cost a restaurant dish to a food-cost target

  A plate that costs $4.20 in ingredients needs to clear the kitchen's 28% food-cost rule, which is the same thing as a 72% margin. Use Cost + Margin %, enter 4.20 and 72, and the menu price lands at $15. The markup readout (about 257%) is the multiple you'll see chefs quote as "price at 3.5x food cost" — seeing both framings confirms the menu price and the food-cost percentage agree before it goes to print.

• Explain markup vs margin to a new team member

  Someone on the team keeps setting "50% margin" by adding 50% to cost. Open Cost + Markup %, enter cost 10 and markup 50 to show the $15 price and 33.3% margin, then switch to Cost + Margin % with the same $10 cost and 50 margin to show the $20 price they actually meant. Two screenshots, side by side, end the argument faster than any whiteboard — and the shareable link lets them replay it later.

Common pitfalls

• Setting a markup percentage when you meant a margin percentage. A 50% markup is only a 33.3% margin, so pricing at 'cost + 50%' when your target was a 50% margin under-charges every order. Decide which base you mean — cost or selling price — before you type the number.

• Pricing off the tax-inclusive amount. Markup and margin must be computed on pre-tax cost and price; folding sales tax into the price inflates the reported margin above the money you actually keep. Keep tax in its own line.

• Trying to push margin to 100% or above. Margin caps below 100% because the formula divides by (1 − margin), and a 100% margin implies zero cost. If you need an extreme multiple over cost, use markup instead, which has no ceiling.
