The CGPA Calculator helps students calculate Cumulative Grade Point Average using semester SGPA, subject grade points, credits and academic performance data. You can use it to calculate CGPA from semesters, SGPA from subjects, CGPA to percentage and target CGPA planning.
This tool is useful for school, college and university students who follow a 10-point grading system. It gives quick results with total credits, total credit points, estimated percentage and academic standing.
What is CGPA?
CGPA stands for Cumulative Grade Point Average. It shows the overall academic performance of a student across multiple semesters or academic terms.
Unlike SGPA, which represents one semester, CGPA combines performance across completed semesters. It is commonly used in colleges, universities and academic records.
What is SGPA?
SGPA stands for Semester Grade Point Average. It measures academic performance in one semester. SGPA is usually calculated using subject credits and grade points earned in that semester.
CGPA is often calculated by combining the SGPA of different semesters with their respective credit weight.
CGPA Formula
The common credit-weighted CGPA formula is:
This method gives more importance to semesters with higher credit load. It is more accurate than simply averaging all SGPAs when semester credits are different.
SGPA Formula
The SGPA formula uses subject credits and grade points:
For example, if a subject has 4 credits and you score 9 grade points, then the credit points for that subject are 4 × 9 = 36.
How to Use the CGPA Calculator
- Open the Semester to CGPA tab.
- Enter each semester name, SGPA and credits.
- Click Calculate CGPA.
- Check your CGPA, total credits and estimated percentage.
- Use the target CGPA tab to plan future performance.
How to Calculate SGPA from Subjects
- Open the Subject to SGPA tab.
- Enter subject names, credits and grade points.
- Click Calculate SGPA.
- Check your semester SGPA and total credit points.
CGPA to Percentage Formula
CGPA to percentage conversion depends on the institution. Some schools and boards use CGPA × 9.5, while some universities use CGPA × 10 or their own formula.
| S.No | Conversion Method | Formula | Common Use |
|---|---|---|---|
| 1 | CBSE / Common Method | Percentage = CGPA × 9.5 | Often used for CBSE-style conversion |
| 2 | Direct 10x Method | Percentage = CGPA × 10 | Used by some colleges and universities |
| 3 | Custom University Rule | As per official institution formula | Best for official academic use |
Example CGPA Calculation
Suppose a student has completed three semesters with the following SGPA and credits:
| S.No | Semester | SGPA | Credits | Credit Points |
|---|---|---|---|---|
| 1 | Semester 1 | 8.2 | 20 | 164 |
| 2 | Semester 2 | 8.6 | 22 | 189.2 |
| 3 | Semester 3 | 8.9 | 21 | 186.9 |
Total credit points are 540.1 and total credits are 63. So the CGPA is:
CGPA Grade Range
The table below shows a common 10-point CGPA interpretation. Your institution may follow a different grade scale.
| S.No | CGPA Range | Academic Standing | General Meaning |
|---|---|---|---|
| 1 | 9.0 - 10.0 | Excellent | Very strong academic performance |
| 2 | 8.0 - 8.99 | Very Good | Strong performance |
| 3 | 7.0 - 7.99 | Good | Above average performance |
| 4 | 6.0 - 6.99 | Average | Moderate performance |
| 5 | Below 6.0 | Needs Improvement | Requires stronger academic focus |
CGPA vs SGPA
CGPA and SGPA are related, but they are not the same. SGPA is calculated for one semester, while CGPA is calculated across multiple semesters.
| S.No | Term | Full Form | Meaning |
|---|---|---|---|
| 1 | SGPA | Semester Grade Point Average | Performance in one semester |
| 2 | CGPA | Cumulative Grade Point Average | Overall performance across semesters |
How Target CGPA Planning Works
The target CGPA planner calculates the average SGPA you need in future credits to reach a desired CGPA.
This helps students understand whether their target CGPA is realistic based on remaining semesters and credits.
