The formula
The calculation uses a standard, verifiable formula. Here it is in its simplest form.
What each variable means
| Symbol | Name | Description |
|---|---|---|
| GP | Grade point | The grade point for each subject. |
| N | Subjects | Total number of subjects. |
Step-by-step example
Example: 5 subjects with grade points 9, 8, 10, 7, 9
- 1Sum = 9 + 8 + 10 + 7 + 9 = 43
- 2CGPA = 43 / 5 = 8.6
- 3Percentage ≈ 8.6 × 9.5 = 81.7%
Result
CGPA = 8.6, Percentage ≈ 81.7%
What changes the result
- Each subject's grade point contributes equally (unweighted).
- Some institutions use credit-weighted CGPAs.
- The conversion factor varies by institution.
Edge cases to be aware of
Unusual situations handled correctly
- Zero grade points result in a CGPA of 0.
- Maximum CGPA equals the scale maximum (10 or 4).
- Different institutions may use different conversion formulas.
Common mistakes
Avoid these errors
- Using credit-weighted averages when credits are not provided.
- Assuming the ×9.5 conversion is universal.
- Entering percentages instead of grade points.
Assumptions
- All subjects have equal weight.
- Grade points are on the selected scale.
Limitations
- The percentage conversion is approximate.
- Credit-weighted CGPAs require additional information.
- Different universities may calculate CGPA differently.
