About GPA Calculator
List your courses with credit hours and letter grades (A+ through F, plus and minus included) and get your GPA on the standard 4.0 scale. Weighting by credit hours is on by default so a 4-credit course counts more than a 1-credit seminar; switch it off for a simple average. If your school maps letters differently, every point value in the scale is editable.
Common uses
- Compute a semester GPA before grades are official

- Convert a transcript to the 4.0 scale for applications
Example

Output
GPA 3.57 (weighted) across 7 credit hours
Limitations
- Schools differ on A+ handling, repeats, and pass/fail courses — check your registrar's rules for official numbers.
Frequently asked questions
How is a credit-weighted GPA calculated?
Multiply each course's grade points by its credit hours, add those up, and divide by the total credits: Σ(points × credits) ÷ Σcredits. An A (4.0) in a 4-credit course and a B (3.0) in a 3-credit course gives (16 + 9) ÷ 7 = 3.57.
Is an A+ worth more than an A on the 4.0 scale?
Usually not — the default scale here caps both at 4.0, which is how most US colleges report it. Some schools award 4.3 or 4.33 for an A+, and every point value in this calculator's scale is editable to match your registrar.
Are my grades uploaded when I calculate my GPA?
No. Courses, credits, and grades are processed entirely in your browser and never sent to a server, so your academic record stays on your device.
Why does a low grade in a big course hurt my GPA so much?
With credit weighting on, each course pulls on your GPA in proportion to its credit hours, so a C in a 4-credit course outweighs an A in a 1-credit seminar. Turn weighting off to see the plain unweighted average for comparison.
