How college GPA is calculated
Each course earns quality points: its grade points times its credit hours. A B+ (3.3) in a 3-credit course is 9.9 quality points. Semester GPA is total quality points divided by total credit hours.
Cumulative GPA = (previous GPA × previous credits + this semester's quality points) ÷ (previous credits + this semester's credits).
| Grade | Points | Grade | Points |
|---|---|---|---|
| A+ / A | 4.0 | C+ | 2.3 |
| A- | 3.7 | C | 2.0 |
| B+ | 3.3 | C- | 1.7 |
| B | 3.0 | D+ / D / D- | 1.3 / 1.0 / 0.7 |
| B- | 2.7 | F | 0.0 |
This is the most common US scale. Some colleges don't use plus/minus grades or give A+ a 4.33; your registrar's transcript is the official number.
Frequently asked questions
How is college GPA calculated?
Each course's grade points (for example B+ = 3.3) are multiplied by its credit hours. The total is divided by total credit hours.
How do I calculate cumulative GPA?
Multiply your previous GPA by your previous credit hours to get previous quality points, add this semester's quality points, and divide by all credit hours combined.
Do pass/fail or withdrawn classes count?
Usually not. Leave them out, since they typically carry credit but no grade points. Check your registrar's rules.
