GPA Calculator

How grades convert to points

Each letter grade maps to the standard 4.0 scale (A = 4.0 down to F = 0.0, with +/- variants in between), multiplied by that course's credit hours, then averaged across all credits — the same weighted method most US transcripts use. A 3-credit A (4.0) and a 4-credit B+ (3.3), for example, average to a 3.6 GPA weighted by credit hours, not a flat average of the two grade points.

Add every course you want included and the running GPA updates as you go, so you can test out "what if I get a B instead of a B+" scenarios before grades post — useful for figuring out exactly what you need on a final to hit a target GPA.

Unweighted, not honors-boosted

This calculates a standard unweighted GPA on the 4.0 scale. It doesn't add the extra point some high schools give for honors, AP, or IB courses (which can push a weighted GPA above 4.0) — if your school reports a weighted GPA, this tool's number will read lower than your transcript's, and that's expected, not an error.

Semester GPA vs. cumulative GPA

Adding only this term's courses gives your semester GPA; to get a true cumulative GPA, every course from every prior term needs to be entered too, each weighted by its own credit hours — a strong semester genuinely moves a low cumulative GPA less than it feels like it should, precisely because it's averaged against every term that came before it. That's also why one rough semester early on has a smaller permanent effect on a four-year cumulative GPA than it seems like in the moment; there's simply more total credit-weight ahead of it to average against.

What a target GPA actually requires

Working backward from a goal GPA is one of the more useful ways to use this tool: enter your already-locked-in grades for the term, then experiment with the grade on a remaining course to see exactly what you need to hit a target average. Because the calculation is credit-weighted, a single-credit seminar moves the average far less than a 4-credit core class — worth knowing before deciding where to focus study time for a specific GPA goal.
