GPA Formula (4.0 Scale)
Standard US grade points: A/A+ = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D+ = 1.3, D = 1.0, D− = 0.7, F = 0.0
Example: 3-credit A (4.0) + 4-credit B+ (3.3) → (12 + 13.2) ÷ 7 = 3.60

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.
Semester GPA from Your Course List
Registration deadlines, scholarship requirements, and academic probation thresholds all reference GPA — but manual credit-weighted math is tedious. Add courses with grades and credits to see your semester average instantly.
