Summary: Calculate Markup and Selling Price Free, in Your Browser
Markup is the percentage you add to an item's cost to reach its selling price: selling price = cost × (1 + markup %). This markup calculator works in both directions. Enter a cost and a markup percentage to get the price, or enter a cost and a selling price to get the markup. Each result shows the profit, the equivalent margin and the working.
It runs in your browser and nothing is uploaded; the Network tab in DevTools shows no request carrying your costs. The figures cover the item price only, so tax, shipping and fees are not included.
The formulas it uses
- Selling price = Cost × (1 + Markup %), so the profit is Cost × Markup %.
- Markup % = (Selling − Cost) ÷ Cost × 100.
- Margin % = Profit ÷ Selling × 100, which equals Markup ÷ (100 + Markup) × 100.
Because markup is a percentage of cost, the cost must be above zero. The margin calculator starts from the selling price instead, which is the better tool when you are aiming for a target share of revenue.

Features
- Two modes: Find Selling Price (cost plus markup %) and Find Markup % (cost plus selling price).
- Quick markups of 25%, 50%, 75%, 100%, 150% and 200%, and a Common Markup Percentages row that shows each one's equivalent margin.
- Markup vs Margin panel and a Calculation box with your own numbers worked through.
- Copy buttons for the selling price and the markup percentage.
- Currency symbol choice (USD, EUR, GBP, INR, JPY, AUD, CAD or none); it changes the label only and does not convert amounts.
- Flexible input: up to four decimals, with commas and spaces ignored. A price below cost is shown as a loss with a negative markup.
How to Use the Markup Calculator
- Choose a Currency symbol, or No symbol.
- Pick Find Selling Price to price from a markup, or Find Markup % to measure existing prices.

Who Can Use It
Retailers and wholesalers can price stock from supplier invoices, online sellers can check a listing before publishing it, and tradespeople can add a markup to materials on a quote. Students of business can compare markup with margin on the same sale.
Use the discount calculator to see what a sale price leaves you, the percentage calculator for quick percent changes, and the GST calculator or VAT calculator to add tax to the price you set. If supplier costs arrive in another currency, convert them with the currency converter, and for goods priced by weight use the weight converter. Profits may be taxable, so estimate that with the income tax calculator.
FAQs
How do I calculate selling price from cost and markup?
Multiply the cost by (1 + markup), with the markup as a decimal. For an 80 cost at a 50% markup, 80 × 1.50 = 120. The 40 difference is the gross profit on the item. In the calculator, choose Find Selling Price, then enter the cost and the markup percentage.
How do I find the markup percentage from two prices?
Markup % = (selling price − cost) ÷ cost × 100. For a 60 cost and a 90 selling price, (90 − 60) ÷ 60 × 100 = 50%. Choose Find Markup % and enter both prices to get the result with the working shown.
What is the difference between markup and margin?
Both measure the same profit against a different base. Markup compares profit with the cost, while margin compares it with the selling price. Selling at 90 something that cost 60 is a 50% markup but only a 33.33% margin, so the markup figure is always larger for the same sale.
How do I convert markup to margin?
Margin = markup ÷ (1 + markup), using decimals. A 50% markup is 0.5 ÷ 1.5 = 33.33% margin, a 100% markup is a 50% margin and a 25% markup is a 20% margin. The calculator shows the margin beside every markup it computes.
What is the difference between 100% markup and 100% margin?
A 100% markup doubles the cost: a 50 cost sells for 100, which is a 50% margin. This is often called keystone pricing. A 100% margin would need a cost of zero, so it cannot happen on goods you pay for. Always check which of the two a person means.
Can markup be negative?
Yes. If you sell below cost, for example in a clearance sale, the markup is negative and each sale loses money. A cost of 100 sold at 80 is a −20.00% markup and a −25.00% margin. The calculator labels it a loss and shows the negative figures.
Is it safe to type my wholesale costs into this markup calculator?
Yes. The calculation happens in your browser and nothing is uploaded. Open the Network tab in DevTools while you type to confirm that no request carries your costs. The calculator keeps nothing after you close the page, and the copy buttons write only to your own clipboard.
