Markup Calculator

Markup Calculator adds a percent of the cost onto the cost and shows that selling price. It does not compute a margin from revenue.

Cost times the percent

The fields are Cost and Markup %. The form opens on 80 and 25. Markup amount is cost times the percent divided by 100. Selling price is cost plus that amount. 80 times 0.25 is 20, and 80 plus 20 is 100. The lines read Markup amount: 20 and Selling price: 100. The button says Calculate Markup. A US locale prints those as whole numbers. Last checked: October 2026, against markupCalc. A cost of 80 at 0 percent is a markup of 0 and a selling price of 80. A negative percent is allowed: 80 at minus 10 percent is a markup of -8 and a selling price of 72.

Why this is not a margin

A margin divides profit by the selling price. This form divides the markup by the cost. 20 of profit on a 100 price is a 20 percent margin and also a 25 percent markup on an 80 cost. Those percents are not interchangeable. If the note you have is a margin, do not type it into Markup %. A negative cost stops with Cost cannot be negative. There is no tax field and no quantity field. One cost, one percent. The two result lines do not print a currency symbol. 20 profit on a 100 price is the 20 percent margin that matches the default 25 percent markup, and this form will not print that 20 percent line.

A second cost to check

A cost of 40 at 50 percent is a markup of 20 and a selling price of 60. A cost of 200 at 10 percent is a markup of 20 and a selling price of 220. If 80 and 25 do not show 20 and 100, the fields are not the defaults. The result uses the same units you typed. It does not round to a price ending in .99. Two-decimal formatting applies when the product is not a whole number. 33 at 10 percent is a markup of 3.3 and a selling price of 36.3. 40 at 50 percent is a markup of 20 and a selling price of 60. That pair matches the worked example.

One price, not a catalog

The numbers stay in this browser. Use the selling price as the figure you will charge before tax. Sales tax is a different calculator. This page will not tell you whether 25 percent is a strong markup for a product. A cost of 15 at 10 percent is a markup of 1.5 and a selling price of 16.5. Those keep one decimal because 1.5 is not a whole number after the two-digit format. A cost of 0 at 25 percent is a markup of 0 and a selling price of 0. Zero is allowed. A blank cost throws Enter a valid number before the formula runs. Type 0 if you mean a zero cost.
