Margin Calculator - Gross Profit & Markup
Calculate your profit margins, markup, and gross profit instantly. Our free Margin Calculator runs entirely locally, ensuring your sensitive business pricing remains 100% private.
What is the Margin Calculator?
Pricing products correctly is the difference between a thriving business and bankruptcy. However, many business owners confuse 'Markup' (percentage of cost) with 'Margin' (percentage of selling price). This calculator eliminates the confusion. By entering your item cost and desired revenue, it instantly calculates the exact Gross Profit, Margin Percentage, and Markup Percentage. Because wholesale costs and pricing strategies are highly confidential trade secrets, this tool was built to run exclusively via client-side JavaScript. Your financial data is never transmitted to our servers.

- Instant Economics: See exactly how much pure profit you make per item.
