The formula
The calculation uses a standard, verifiable formula. Here it is in its simplest form.
GPA = Σ(Grade × Credits) / Σ(Credits)
What each variable means
| Symbol | Name | Description |
|---|---|---|
| Grade | Grade point | The grade point for each course. |
| Credits | Credit hours | The credit weight of each course. |
Step-by-step example
Example: 4 courses with grades and credits
Courses:4Course 1:A (4.0, 3 cr)Course 2:B (3.0, 4 cr)Course 3:A (4.0, 3 cr)Course 4:B+ (3.3, 3 cr)
- 1Total points = (4.0×3) + (3.0×4) + (4.0×3) + (3.3×3) = 12 + 12 + 12 + 9.9 = 45.9
- 2Total credits = 3 + 4 + 3 + 3 = 13
- 3GPA = 45.9 / 13 = 3.53
Result
GPA = 3.53
What changes the result
- Credit hours determine how much each course affects your GPA.
- Higher grades in high-credit courses boost GPA more.
- The scale determines the maximum possible GPA.
Edge cases to be aware of
Unusual situations handled correctly
- Zero credits result in an undefined GPA.
- Maximum GPA equals the scale maximum.
Common mistakes
Avoid these errors
- Using unweighted averages instead of credit-weighted.
- Entering letter grades instead of grade points.
Assumptions
- All grades are on the selected scale.
- Credit hours are correctly entered.
Limitations
- Different institutions may use different grade point values.
- Plus/minus grading may vary by institution.
Frequently asked questions
What is the difference between GPA and CGPA?+
GPA typically refers to a single semester or term average. CGPA (Cumulative GPA) is the average across all semesters. Both use the same credit-weighted calculation method.
How do I convert letter grades to grade points?+
On a 4.0 scale: A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, D=1.0, F=0.0. Values may vary slightly by institution.
