About this site
This site does one thing: calculate high school GPAs quickly and correctly. No signup, no ads in the calculator, no spinner while a framework loads — enter your grades, get your number.
Why we built it
Most GPA calculators are either buried in ad-heavy pages or too generic to handle how high schools actually grade — weighted vs unweighted scales, credit hours vs no credits, and university systems like the UC and UF that recalculate GPAs with their own rules. We built dedicated tools for each case, plus plain-English guides for the questions behind the number.
How the calculators work
All math runs in your browser — your grades are never sent to a server, stored, or tracked. The formulas follow the most common US conventions (documented on every tool page), and the UC and UF calculators follow those universities' published recalculation rules, which we review periodically. Your school or a university may still compute things slightly differently — for decisions that matter, verify with your counselor or the institution's official site.
