How is GPA Calculated?
Your Grade Point Average (GPA) is a numerical representation of your academic performance. It is calculated by dividing the total number of grade points earned by the total number of credit hours attempted.
The standard formula used by most universities and high schools is:
GPA = Σ (Grade Points × Credit Hours) / Total Credit Hours
The 4.0 GPA Scale
Most institutions in the United States use a 4.0 scale. Below is the standard conversion chart used for these calculations:
| Letter Grade | Percentage | Grade Points |
|---|---|---|
| A | 93–100 | 4.0 |
| A- | 90–92 | 3.7 |
| B+ | 87–89 | 3.3 |
| B | 83–86 | 3.0 |
| B- | 80–82 | 2.7 |
| C+ | 77–79 | 2.3 |
| C | 73–76 | 2.0 |
| F | Below 60 | 0.0 |
Weighted vs. Unweighted GPA
Unweighted GPA: This treats every class the same, regardless of difficulty. An 'A' in an AP Physics class is worth the same (4.0) as an 'A' in a regular physical education class.
Weighted GPA: This accounts for course difficulty. Often, Honors classes are given an extra 0.5 points, and AP or IB classes are given an extra 1.0 point, meaning a student could potentially achieve a GPA higher than 4.0.
Calculation Example
Imagine you took three classes:
- English: Grade A (4.0), 3 Credits. Points = 12.0
- Math: Grade B (3.0), 4 Credits. Points = 12.0
- History: Grade C (2.0), 3 Credits. Points = 6.0
Total Points: 12 + 12 + 6 = 30.0
Total Credits: 3 + 4 + 3 = 10
Resulting GPA: 30.0 / 10 = 3.00
