Markup Calculator: The Complete Guide

Find the selling price from cost and markup. Everything you need to know — plus a free tool to do it instantly.

What is markup?

Markup is the percentage added to cost price to arrive at a selling price. Unlike margin (which is a % of selling price), markup is a % of cost. This calculator lets you work in either direction: find selling price from cost + markup %, or find markup % from known cost and price. It also converts between markup and margin so you can work in whichever metric your business prefers.

How it works

Enter cost price and markup % to get selling price, OR enter cost price and selling price to get markup %. The tool simultaneously shows the equivalent gross margin % for comparison.

Why it matters

Many retail and wholesale businesses set prices using markup tables. Knowing the exact markup-to-margin conversion prevents systematic underpricing.

Common mistakes

Applying markup % as if it were margin % — a 50% markup is only a 33.3% margin

Best practices

Build a markup table for your product categories at different target margins
Review markup on slow-moving stock — it may be priced too high
