About Gradeculator

Gradeculator is a free collection of grade and GPA calculators built for students who need quick, accurate answers — without signing up, logging in, or sharing their data.

What it is

Whether you need to work out what score you need on your final exam to pass a class, calculate your weighted GPA across multiple semesters, or figure out what percentage a test score equals — Gradeculator has a dedicated tool for each scenario:

• GPA Calculator — standard 4.0-scale GPA from your grades and credit hours
• Cumulative GPA Calculator — combine multiple semesters into a running GPA
• Weighted GPA Calculator — honours and AP courses included
• Final Grade Calculator — the grade you need on your final to hit your target
• Test Grade Calculator — convert marks to a percentage or letter grade instantly

Who it's for

Gradeculator is built for high-school and college students, but anyone who needs to work with grades and grade-point averages will find it useful. Parents checking their student's standing, teachers verifying calculations, and international students converting between grading systems are all welcome.

Why it's free

Gradeculator is kept free by advertising. Ads are displayed by Google AdSense, and we ask for your consent before any personalised advertising cookies are set. Your grades and inputs never leave your browser — all calculations happen locally on your device.

Who built it

Gradeculator is an independent project built and maintained by a small team of developers who believe useful tools should be free, fast, and respectful of your privacy. There is no investor funding, no subscription, and no upsell — just a calculator that works.
