What Are SGPA and CGPA?
If you are a student in an Indian university or any institution using a 10-point grading scale, you have likely come across the terms SGPA (Semester Grade Point Average) and CGPA (Cumulative Grade Point Average). Understanding these two metrics is essential for tracking your academic progress.
SGPA is the weighted average of grade points you earned in all subjects during a single semester.
CGPA is the cumulative weighted average across all semesters you have completed so far.
The Formula
The CGPA formula is:
CGPA = Σ (SGPA × Credits) ÷ Σ Credits
Where:
- Σ means “sum of”
- Credits = credit hours assigned to each semester
Step-by-Step Example
Let us say a student has completed 4 semesters:
| Semester | SGPA | Credits |
|---|---|---|
| 1 | 8.0 | 20 |
| 2 | 8.5 | 22 |
| 3 | 7.8 | 24 |
| 4 | 9.0 | 24 |
Calculation:
Total Weighted = (8.0×20) + (8.5×22) + (7.8×24) + (9.0×24) = 160 + 187 + 187.2 + 216 = 750.2
Total Credits = 20 + 22 + 24 + 24 = 90
CGPA = 750.2 ÷ 90 = 8.34
Converting CGPA to Percentage
Most universities accept the formula:
Percentage = CGPA × 9.5
So a CGPA of 8.34 equals: 8.34 × 9.5 = 79.23%
This formula is recommended by Anna University and widely used across Indian engineering colleges.
