Frequently asked questions
How is GPA calculated?
GPA = total grade points ÷ total credits. Grade points = letter grade value × credit hours for each course. Example: A (4.0) in 3 credits = 12 points.
Are plus and minus grades supported?
Yes. A− = 3.7, B+ = 3.3, and so on using the standard 4.0 scale.
What is the difference between semester and cumulative GPA?
Semester GPA covers one term. Cumulative GPA averages all terms — add prior GPA and credits if your school provides them.
Does this use a weighted 5.0 scale?
This calculator uses the standard 4.0 unweighted scale. Honors or AP weighting varies by school — confirm with your institution.
Is this GPA calculator free?
Yes. Unlimited courses with no signup.
