GPA Calculator
Enter each course's letter grade and credit hours to compute your grade point average on the standard unweighted 4.0 scale, with total credits and grade points shown.
Quick answer: GPA = total grade points ÷ total credits, where an A is worth 4.0, B is 3.0, C is 2.0, and D is 1.0 per credit. Three credits of A and three credits of B average to a 3.5 GPA.

Unweighted 4.0 scale: each course's grade points are multiplied by its credits, summed, and divided by total credits. Rows marked “—” or with 0 credits are skipped. The +/− values shown are the common convention, but schools vary — check your institution's scale.
How it works
1. Enter grades and credit hours
Add each course's letter grade and its credit hours. Courses with no grade or zero credits are simply ignored, so you can leave unused rows blank.
2. Grades become grade points
Each letter maps to points on the 4.0 scale — A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, down to F = 0 — and each course earns points × credits, so heavier courses move your GPA more.
3. Divide points by credits
GPA is total grade points divided by total credit hours. Semester GPA uses just this term's courses; cumulative GPA uses every course you've taken.
Frequently asked questions
How is GPA calculated?
Multiply each course's grade points (A = 4.0, B = 3.0, C = 2.0, D = 1.0) by its credit hours, add them up, and divide by total credit hours. A 3-credit A and a 4-credit B is (12 + 12) ÷ 7 ≈ 3.43.
What GPA do the plus and minus grades give?
The common convention is A− = 3.7, B+ = 3.3, B− = 2.7, C+ = 2.3, and so on in 0.3 steps. Most schools use this scale, but some don't count an A+ above 4.0 or skip +/− entirely — check your school's registrar.
What's a good GPA?
A 3.0 (B average) is solid, 3.5+ is strong and typically earns dean's-list recognition, and 3.7+ is competitive for graduate programs. Many scholarships and internships set a 3.0 minimum.
