About this tool

Markup Calculator turns the four most common retail-pricing questions into one tool. Pick a mode and the calculator does the algebra in your browser: cost plus a markup percent gives the selling price (and the resulting margin); cost and a chosen selling price give both the markup and margin percents and the gross profit per unit; cost and a target margin percent give the price you need to charge to hit that margin; and a selling price plus a target margin percent give the maximum cost you can pay to hit that margin (useful when sizing a wholesale order against a fixed retail price). Markup is computed as (price minus cost) divided by cost, expressed as a percent of cost. Margin is computed as (price minus cost) divided by price, expressed as a percent of price. They are not the same number, which is why the page also shows a permanent Markup vs Margin panel that converts between the two for the same scenario, with the formulas printed underneath: 25% markup is a 20% margin, 50% markup is a 33.33% margin, 100% markup (keystone pricing) is a 50% margin, and 200% markup is a 66.67% margin. Optional quantity multiplies the per-unit numbers into total revenue, total cost, and total gross profit so you can size a small batch or a full order in the same calculation. Optional sales tax adds a tax-on-top retail price for display, while keeping markup and margin computed pre-tax the way retailers actually price items. A currency selector formats every money value through Intl.NumberFormat in eight common currencies (USD, EUR, GBP, CAD, AUD, JPY, INR, TRY) without any FX conversion. Useful for ecommerce sellers pricing new SKUs, freelancers and agencies setting cost-plus rates, retailers and resellers checking margin against a wholesale invoice, restaurants pricing menu items off food cost, dropshippers and Etsy/Shopify sellers running a quick price test, finance students and bookkeepers practicing the markup-to-margin conversion, and anyone trying to settle the markup-vs-margin question once. Everything runs locally on your device, so the cost numbers and price tests you type stay in your browser.
