Grade Calculator School is hard enough. The math shouldn’t be.
Grade Calculator started with a simple observation: students check their grades constantly, but every grade tool on the internet looks like a tax form. Boring, intimidating, and about as fun as the homework itself.
So we built the opposite — grade calculators that feel like games. Drop in your scores, flip power-ups like dropping your lowest quiz, set a goal, and watch your grade pop out like a prize. Underneath the playfulness is real math: weighted averages, GPA scales, and grade projections, all verified and explained in plain English.
What you’ll find here
- Six free calculators — grade calculator, final grade calculator, GPA and weighted GPA calculators, grade percentage, and GPA-to-percentage converter.
- Cheat-code guides — short, honest explainers on GPA math, grading scales, and country-specific systems (UK, India, Pakistan, and more).
- Zero friction — no accounts, no sign-ups, no paywalls. Your numbers never leave your browser.
Our promise
Every calculator on this site is free forever. We show ads to keep the lights on (that’s how free stays free), but we’ll never sell your data — mostly because we never collect it in the first place. Calculations happen entirely in your browser; nothing you type is sent to our servers.
Made for students who’d rather be playing. 💛
