About the GPA Calculator
Turn a pile of letter grades into a single number: this GPA calculator converts each course grade to grade points on the standard 4.0 scale, weights it by credit hours and averages the lot. Add as many courses as your semester holds — there's no cap — and the result updates the moment you change a grade or a credit value. No spreadsheet formulas, no registrar visit required.
Students use it to check where the term is heading before finals, to see whether that scholarship's 3.5 cutoff is still in reach, or to test what-if scenarios — how much would an A in a 4-credit course lift the average? Because credit hours weight every grade, a heavy lab course moves your GPA far more than a one-credit seminar, and the calculator makes that visible instantly.

Frequently asked questions
How is GPA calculated on the 4.0 scale?
Each letter grade maps to grade points — A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0, with plus and minus steps in between. Multiply each course's points by its credit hours, add everything up, then divide by total credits. That weighted average is your GPA.
What's the difference between weighted and unweighted GPA?
This calculator produces an unweighted GPA, where an A is 4.0 in any class. Some high schools award weighted GPAs that add bonus points for honors or AP courses, pushing the scale above 4.0. Colleges typically recalculate applicants' grades on the standard unweighted 4.0 scale anyway.
Does an A+ count as more than 4.0?
At most institutions A+ and A both convert to 4.0, which is how this calculator treats them. A handful of schools award 4.3 for an A+, so check your registrar's policy if you're computing an official figure; the difference is usually small once averaged across a full course load.
How do credit hours affect my GPA?
Credits act as weights. A grade in a 4-credit course counts four times as much as the same grade in a 1-credit course. That's why a weak result in a heavy course drags the average down more — and why raising grades in high-credit classes is the fastest way to lift a GPA.
Can I calculate a cumulative GPA across semesters?
Yes. Enter every course from all semesters in one list — cumulative GPA is simply total grade points divided by total credit hours attempted across your whole record. Adding courses is unlimited, so a full multi-year transcript fits fine; just be consistent about which attempts your school actually counts.
