Introduction
Calculate a semester or term GPA from course grade points and optional credit hours. Works with 4.0 or 10.0 scales as long as you enter consistent points.
Formula
GPA is the credit-weighted average of grade points. If credits are omitted, each course counts equally.
- g_i — Grade points for course i
- c_i — Credit hours for course i
Step-by-step
- Enter grade points for each course (comma-separated).
- Optionally enter matching credit hours.
- Review GPA, quality points, and total credits.
Worked example
With grade points 4, 3.7, 3.3, 4 and credits 3, 3, 4, 2, quality points are 43.3 over 12 credits → GPA ≈ 3.6083.
Use cases
- Compute semester GPA from transcript grades
- Weight honors courses by credit hours
- Estimate GPA before final marks are posted
Frequently asked questions
How do letter grades map to points?

What if I leave credits blank?
Each course is weighted equally (1 credit each).
