SGPA (Semester Grade Point Average) is the average grade point a student earns in one semester. It measures academic performance for a particular semester based on the grades and credit points of all subjects. For example, if a student scores good grades in all subjects during Semester 1, the calculated average grade point for that semester is called the SGPA.
CGPA (Cumulative Grade Point Average) is the overall average grade point earned across all semesters of a course or degree program. It represents the student’s cumulative academic performance throughout the entire course.For example, if a student completes four semesters, the average of all four semesters' SGPAs becomes the CGPA.

What is SGPA?
SGPA is the Semester Grade Point Average, which reflects your academic performance in a particular semester. It is calculated by averaging the grade points (GP) you earn in each subject, weighted by the subject’s credit hours.
SGPA Formula:
| SGPA=∑Credits∑(Grade Points×Credits) |
Example:
| Subject | Credits | Grade | Grade Points | Grade Points × Credits |
|---|---|---|---|---|
| Math | 4 | A | 10 | 40 |
| Physics | 3 | B+ | 9 | 27 |
| History | 2 | A- | 9 | 18 |
| English | 3 | B | 8 | 24 |
Total: 40 + 27 + 18 + 24 = 109
SGPA = 109 ÷ 12 (Total Credits) = 9.08
What is CGPA?
CGPA is the Cumulative Grade Point Average, a measure of a student’s overall academic performance across all semesters. It is calculated by averaging the SGPA scores across all completed semesters.
CGPA Formula:
| CGPA=Total Semesters∑(SGPAs of All Semesters) |
Example:
If a student completes 4 semesters with the following SGPA scores:
- Semester 1: 8.5
- Semester 2: 9.0
- Semester 3: 8.8
- Semester 4: 9.2
CGPA = 8.5+9.0+8.8+9.2 = 35.5 / 4 = 8.875

SGPA vs CGPA: Key Differences
Here are some key differences between SGPA and CGPA over multiple aspects:
| Feature | SGPA | CGPA |
|---|---|---|
| Scope | Reflects performance in a single semester | Reflects overall academic performance |
| Calculation | Based on individual subjects and credits | Based on the cumulative SGPA of all semesters |
| Usage | Helps identify strengths/weaknesses per semester | Provides a holistic view of academic progress |
| Importance | Used for semester-specific evaluations and admissions | Used for overall academic assessment, scholarships, and future prospects |
How to Convert SGPA to CGPA?
The conversion from SGPA to CGPA is simple. You need to calculate the weighted average of all your semester SGPA scores. Here’s the step-by-step process:
- List all your SGPA for each semester.
- Add the SGPA together.
- Divide the sum by the total number of semesters completed.
Example:
| Semester | SGPA |
|---|---|
| Semester 1 | 8.5 |
| Semester 2 | 9.0 |
| Semester 3 | 8.8 |
| Semester 4 | 9.2 |
| CGPA = 8.5+9.0+8.8+9.2 = 35.5 / 4 = 8.875 |
UGC Approved Grade Points for Indian Students
Indian universities use a 10-point grading system, where each grade corresponds to a specific point value. Here’s how the SGPA grades convert to points:
| Percentage | Letter Grade | Grade Point |
|---|---|---|
| 90-100% | O (Outstanding) | 10 |
| 80-89% | A+ (Excellent) | 9 |
| 70-79% | A (Very Good) | 8 |
| 60-69% | B+ (Good) | 7 |
| 50-59% | B (Average) | 6 |
| 40-49% | C (Pass) | 5 |
| Below 40% | F (Fail) | 0 |
