What We Do
GPA Calculator is a free online tool that helps you calculate your GPA from course grades using standard and weighted scales. All calculations and lookups run instantly in your browser — no account required, no personal data collected.
Our Mission
We believe education information should be accessible to everyone. Government data, regulations, and technical specifications are often buried in hard-to-navigate sources. GPA Calculator consolidates this information into a single, easy-to-use tool that gives you answers in seconds.
How It Works
Enter your details and get results immediately. Our calculations are based on publicly available data from official sources. We regularly review and update our data to ensure accuracy.
Data Sources
Our data comes from authoritative public sources, including:
- Standard 4.0 GPA scale
- Common weighted GPA methodologies
- College Board GPA guidelines
Who Runs This Site
GPA Calculator is part of Niche Tools, an independent project built and maintained by Adam B., a Brooklyn-based developer. Niche Tools builds free, focused reference tools that turn scattered public data — government tables, municipal codes, agency datasets — into answers you can actually use. There is no staff of ghostwriters and no AI-spun filler: each site is built from primary sources, and we cite them.
Editorial Standards
Every data point on this site traces back to a public primary source. When we summarize regulations or statistics, we link the official source so you can verify it yourself. When something is not specified in the source material, we say "not specified" rather than guessing. If you find an error, please report it — corrections ship quickly.
Important Disclaimer
The results provided by GPA Calculator are estimates for informational purposes only. They are not a substitute for professional advice. Always consult a qualified professional before making important decisions based on these results.
Privacy
We take your privacy seriously. GPA Calculator does not collect personal information, require sign-ups, or sell data. Calculator inputs are processed entirely in your browser. Read our full privacy policy for details.
