Quick Answer
GPA formula: multiply each grade's point value (A=4.0, B=3.0, C=2.0, D=1.0, F=0) by the course credits. Sum all products. Divide by total credits. Example: two 3-credit A's and one 3-credit B = (4.0×3 + 4.0×3 + 3.0×3) ÷ 9 = 33 ÷ 9 = 3.67 GPA.
GPA = Sum of (Grade Points × Credits) ÷ Total Credits
Where grade points are the numeric value assigned to each letter grade:
| Letter Grade | GPA Points | Percentage Range |
|---|---|---|
| A+ or 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 | 1.0 | 63–66% |
| F | 0.0 | 0–59% |

Step-by-Step Example
Let's say you completed these 5 courses this semester:
| Course | Grade | Credits | Quality Points |
|---|---|---|---|
| English Composition | A | 3 | 4.0 × 3 = 12.0 |
| Calculus I | B+ | 4 | 3.3 × 4 = 13.2 |
| Intro to Psychology | A− | 3 | 3.7 × 3 = 11.1 |
| Chemistry Lab | B | 2 | 3.0 × 2 = 6.0 |
| History of Art | C+ | 3 | 2.3 × 3 = 6.9 |
| Totals | 15 | 49.2 quality points |
GPA = 49.2 ÷ 15 = 3.28
