How College GPA Is Calculated
College GPA is calculated using a credit-hour-weighted average of grade points across all courses in a semester, then aggregated across all saved semesters for the cumulative GPA.
US Grade Point Scale:
| Letter Grade | 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 |
| F | 0.0 |
Semester GPA Formula: Semester GPA = Σ (Grade Points × Credit Hours) ÷ Total Semester Credit Hours
Example for three courses:
| Course | Grade | Credits | Quality Points |
|---|---|---|---|
| Psychology | A | 3 | 4.0 × 3 = 12.0 |
| Statistics | B+ | 3 | 3.3 × 3 = 9.9 |
| English | A− | 3 | 3.7 × 3 = 11.1 |
| Total | 9 | 33.0 |
Semester GPA = 33.0 ÷ 9 = 3.67
Cumulative GPA Formula: Cumulative GPA = Σ (All Quality Points Across Saved Semesters) ÷ Σ (All Credit Hours Across Saved Semesters)
