About
Percentages made simple
PercentageSnap is a free collection of percentage calculators and plain-language guides built to make everyday math quicker and easier to check.
What PercentageSnap does
The calculators cover common questions such as finding a percentage of a number, measuring a percentage change, working backward from a discounted price, calculating a tip, and dividing a bill by percentage. Results update in your browser as you type.
The guides explain the reasoning behind those calculations so you can understand the answer, spot mistakes, and repeat the method when a calculator is not available.
Who it is for
PercentageSnap is for shoppers comparing discounts, households checking bills, travelers working out tips, students learning percentage formulas, and small businesses making quick everyday estimates. It is designed for anyone who wants a clear answer without an account, subscription, or complicated setup.
Simple and private by design
PercentageSnap is free, and you never need an account or subscription. Calculations run locally in your browser, and the numbers you type are not sent to our servers by the calculators. Recent calculations and saved results are kept in your browser’s own storage on your device, where you can clear them at any time. The calculator page shows clearly labeled ads from Google, which may use cookies. Read the full Privacy Policy for details.
The guides offer general mathematical education, and the tools provide estimates, not financial, tax, legal, or accounting advice. For important decisions, check the figures independently and use the rules that apply where you live. See the full Disclaimer.
