About PercentScope

PercentScope is a free calculator platform for percentage, discount, margin and pricing questions. It is designed to give people a useful answer immediately, then show the formula and context behind that answer.

What makes PercentScope different

We focus on live calculation, transparent steps, visual explanations and real-world tools such as stacked discounts, margin vs. markup, chained percentages and batch calculations. Core calculations run locally in your browser.

Business model

PercentScope is supported by advertising. We keep ad placements separate from calculator controls so the tool remains the main focus of every page.
