PercentMaster Reviews and Details

This page is designed to help you find out whether PercentMaster is good and if it is the right choice for you.

PercentMaster is a free, no-signup web app with 50+ calculators and utilities that run client-side.

Why I Built It

The catalyst was simple frustration. I'd reach for a calculator tool, and the experience would be one of:

Bloated UI. Ads, pop-ups, and dark patterns everywhere.
Friction to use. Sign up, verify email, accept cookies, then calculate.
Privacy concerns. No visibility into whether your inputs were logged or sent somewhere.
Vague or missing explanations. You get a number back. Cool. But what does it mean? When should you actually use this?

What's Inside

Finance & Math

Percentage, discount, tip, and comparison calculators. The bread and butter.
Loan & mortgage calculators with amortization clarity.
Compound & simple interest. See how time and rates compound.
Income tax, sales tax, and salary estimators. Quick snapshots for your location/scenario.
Retirement & investment calculators. Rough projections to think about the long game.
BMI, calorie needs, and macro tracking tools.
GPA calculator. For students, parents, counselors.
Age calculator. Because you might want to know how many days old you are.
Color converter. Hex, RGB, HSL, named colors—fast switching.
Password generator. Configurable length and character sets; no server involved.
Unit converter. Length, weight, volume, temperature.
Currency & crypto converter. Real-time rates (fetched client-side only).
Date calculator. Days between dates, add/subtract intervals.
QR code generator. Text to scannable code instantly.
Base64 encoder/decoder, JSON formatter/minifier, UUID v4 generator, Lorem ipsum generator. All the little things you Google for.
Image compressor. JPEG and WebP, runs entirely in your browser. No uploads to a server.

The utilities lean into privacy: if a tool doesn't need the internet, it doesn't touch it.
