Calculate your Grade Point Average on the 4.0 scale, weighted by credit hours. Add each course's grade and credits and get your GPA instantly.

The Grade Point Average converts letter grades into numbers on a 0–4.0 scale, then averages them with credit hours as weights. Each course contributes (grade points × credits) to a running total, and the GPA is that total divided by the total credits earned. Two students with the same letters but different credit loads can therefore end up with different GPAs.
Each letter grade maps to a number of grade points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0). You multiply the points by the course's credits, sum those products over all courses, and divide by the total credits: GPA = Σ(points × credits) ÷ Σ(credits).
A 4-credit course carries four times the weight of a 1-credit course. A simple unweighted average of letter grades would treat them the same, which is why two students with identical letter grades can end up with different GPAs if their credit loads differ.
The semester GPA covers only the courses of one term, while the cumulative GPA pools every course you have ever taken (or, on this site, everything in the list). Add all courses across all terms to get your cumulative GPA; add only one term's courses for the semester GPA.
Yes. This calculator uses the common 4.0 scale with plus/minus steps: A- = 3.7, B+ = 3.3, B- = 2.7, C+ = 2.3, C- = 1.7, D+ = 1.3. Some institutions use slightly different scales, so check your school's official table before relying on the result.
No. Every course you add and every GPA is computed locally in your browser. Nothing is uploaded, stored or transmitted, and the page keeps working with the internet disconnected.
