The 4.0 GPA scale is the most common system used in high schools to measure academic performance. This calculator helps you convert your letter grades to GPA points and determine your semester GPA.
How to Calculate GPA on 4.0 Scale
The 4.0 GPA scale assigns numerical values to letter grades, with A being the highest (4.0) and F being the lowest (0.0). Here's how to calculate your semester GPA:
GPA Calculation Formula
GPA = (Sum of (Grade Points × Credit Hours)) / (Total Credit Hours)
Step-by-Step Process
- Identify all your courses and their credit hours for the semester.
- Convert each letter grade to its corresponding GPA point value.
- Multiply each grade point by the course's credit hours.
- Sum all the weighted grade points.
- Sum all the credit hours.
- Divide the total weighted grade points by the total credit hours.
Example: If you took a 3-credit course with a B (3.0) and a 4-credit course with an A (4.0), your GPA would be calculated as:
(3.0 × 3) + (4.0 × 4) = 9 + 16 = 25
Total credit hours = 3 + 4 = 7
GPA = 25 / 7 ≈ 3.57
Grade Conversion Table
Here's the standard conversion table from letter grades to GPA points on the 4.0 scale:
| Letter Grade | GPA Points | Description |
|---|---|---|
| A | 4.0 | Excellent |
| A- | 3.7 | Very Good |
| B+ | 3.3 | Good |
| B | 3.0 | Above Average |
| B- | 2.7 | Satisfactory |
| C+ | 2.3 | Average |
| C | 2.0 | Basic |
| C- | 1.7 | Below Average |
| D+ | 1.3 | Passing |
| D | 1.0 | Minimal Passing |
| F | 0.0 | Failing |
Weighted vs Unweighted GPA
Some high schools offer weighted GPA calculations to account for advanced courses. Here's how they differ:
| Type | Description | Calculation |
|---|---|---|
| Unweighted GPA | Standard GPA calculation | Uses standard grade points |
| Weighted GPA | Accounts for advanced courses | Adds 0.5 to grade points for honors/AP courses |
For example, a B in an AP course would be calculated as 3.5 (3.0 + 0.5) instead of 3.0. Your school may have different weighting systems, so check with your counselor.
