How is College GPA Calculated?
Your Grade Point Average (GPA) is a weighted average of your performance across all your classes. To calculate it, we assign a numerical value to your letter grades and multiply them by the number of credit hours assigned to that course.
The standard formula is:
GPA = Total Quality Points / Total Credit Hours
The Standard 4.0 Grading Scale
| Letter Grade | Grade Points | Percentage Range |
|---|---|---|
| A | 4.00 | 93-100% |
| A- | 3.70 | 90-92% |
| B+ | 3.30 | 87-89% |
| B | 3.00 | 83-86% |
| B- | 2.70 | 80-82% |
| C+ | 2.30 | 77-79% |
| C | 2.00 | 73-76% |
Why Credits Matter
A course worth 4 credits has a much larger impact on your GPA than a 1-credit lab. For example, getting an 'A' in a 4-credit Calculus class provides 16 quality points (4.0 x 4), whereas an 'A' in a 1-credit PE class provides only 4 quality points.
Practical Example
If you take three classes:
- Psychology: 3 Credits, Grade: A (4.0) → 12 Points
- Math: 4 Credits, Grade: B (3.0) → 12 Points
- History: 3 Credits, Grade: C (2.0) → 6 Points
Total Points = 30. Total Credits = 10.
GPA = 30 / 10 = 3.00
