GPA formula
GPA = Σ (grade points × credits) ÷ Σ credits
Example: A (4.0) in a 3-credit course, B+ (3.3) in a 4-credit course, A− (3.7) in a 3-credit course and C (2.0) in a 2-credit course. Grade points: 12 + 13.2 + 11.1 + 4 = 40.3. Credits: 12. GPA = 40.3 ÷ 12 = 3.36.
Grade point scale (4.0)
| Letter | Points | Typical % |
|---|---|---|
| A / A+ | 4.0 | 93–100 |
| A− | 3.7 | 90–92 |
| B+ | 3.3 | 87–89 |
| B | 3.0 | 83–86 |
| B− | 2.7 | 80–82 |
| C+ | 2.3 | 77–79 |
| C | 2.0 | 73–76 |
| C− | 1.7 | 70–72 |
| D+ / D / D− | 1.3 / 1.0 / 0.7 | 60–69 |
| F | 0.0 | Below 60 |

Frequently asked questions
How is GPA calculated?
Each letter grade is converted to grade points (A = 4.0, B = 3.0, etc.), multiplied by the course’s credit hours, and the total is divided by the total credit hours attempted.
Is an A+ worth more than 4.0?
At most U.S. colleges an A+ is capped at 4.0, which is what this calculator uses. Some schools award 4.3 for an A+; check your school’s policy.
How do I calculate my cumulative GPA?
Enter your current cumulative GPA and total credits completed. The calculator combines them with this term’s courses: (old GPA × old credits + new grade points) ÷ (old credits + new credits).
Do pass/fail courses count?
Usually not. Pass/fail and withdrawn courses typically do not affect GPA, so leave them out. A failing grade (F) normally counts as 0 points with full credit hours.
