Review Instant Results
The calculator instantly computes your term GPA, total credits earned, and total quality points.
Weighted GPA Calculation Formula
Grade Point Average (GPA) is computed by dividing total quality points by the sum of total credit hours across all courses.
GPA = Σ (Grade Points × Course Credit Hours) / Σ (Course Credit Hours)
For example, if you take a 4-credit course with an A (4.0 points = 16 quality points) and a 3-credit course with a B (3.0 points = 9 quality points), your total quality points are 25 and total credits are 7. GPA = 25 / 7 = 3.57.
| Letter Grade | Percent Equivalent | Grade Points (4.0 Scale) |
|---|---|---|
| A+ / A | 93% – 100% | 4.00 |
| A- | 90% – 92% | 3.70 |
| B+ | 87% – 89% | 3.30 |
| B | 83% – 86% | 3.00 |
| B- | 80% – 82% | 2.70 |
| C+ | 77% – 79% | 2.30 |
| C | 73% – 76% | 2.00 |
| D | 65% – 69% | 1.00 |
| F | Below 65% | 0.00 |

Pro Tips for Best Results
- Focus high effort on higher-credit courses: an A in a 4-credit lab will influence your GPA more than an A in a 1-credit seminar.
- Check if your institution uses unweighted 4.0 or weighted 5.0 (for AP/Honors courses).
- Retaking a course can significantly improve your GPA if your university allows grade replacement.
