The 4.0 GPA scale is the most common grading system in the United States, where A = 4.0, B = 3.0, and so on. This calculator helps you convert letter grades to GPA points and calculate your overall GPA.
How to Calculate GPA 4.0
Calculating your GPA on a 4.0 scale involves these steps:
- Convert each letter grade to its corresponding grade point value
- Multiply each grade point by the number of credit hours for that course
- Sum all the weighted grade points
- Sum all the credit hours
- Divide the total weighted grade points by the total credit hours
GPA Formula
GPA = (Σ (Grade Point × Credit Hours)) / (Σ Credit Hours)
For 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:
(3.0 × 3) + (4.0 × 4) = 12 + 16 = 28 total grade points
3 + 4 = 7 total credit hours
28 ÷ 7 = 4.0 GPA
GPA Scale Conversion
The 4.0 GPA scale is different from other grading systems. Here's how to convert between them:
| Letter Grade | 4.0 Scale | Percentage Range |
|---|---|---|
| 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% |
| D | 1.0 | 60-69% |
| F | 0.0 | Below 60% |
Note: Some institutions may use slightly different grade point values. Always check your institution's specific grading scale.
Grade Point Values
Each letter grade corresponds to a specific grade point value on the 4.0 scale:
- 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
These values are used to calculate your weighted GPA, where higher credit courses count more toward your overall GPA.
Example Calculation
Let's calculate a GPA for a student who took these courses:
| Course | Credit Hours | Letter Grade | Grade Points |
|---|---|---|---|
| English | 3 | B | 3.0 |
| Mathematics | 4 | A | 4.0 |
| History | 3 | A- | 3.7 |
| Science | 4 | B+ | 3.3 |
Calculation steps:
- English: 3.0 × 3 = 9.0
- Mathematics: 4.0 × 4 = 16.0
- History: 3.7 × 3 = 11.1
- Science: 3.3 × 4 = 13.2
- Total grade points: 9.0 + 16.0 + 11.1 + 13.2 = 49.3
- Total credit hours: 3 + 4 + 3 + 4 = 14
- GPA: 49.3 ÷ 14 = 3.52
The student's GPA is 3.52 on the 4.0 scale.

- GPA is calculated by multiplying each grade's point value by the course's credit hours, summing these values, and then dividing by the total credit hours attempted.
- What counts toward GPA?
- All graded courses count toward GPA, including A-F grades. Pass/fail courses typically do not count toward GPA.
- Can I have a GPA higher than 4.0?
- No, the maximum GPA on a 4.0 scale is 4.0. Some institutions may use a 5.0 scale where A = 5.0.
