CGPA Calculator 2025: Easy Formula to Convert CGPA into Percentage
What is CGPA?
CGPA means Cumulative Grade Point Average. It shows how well a student has done across all subjects during a whole term, year or course. Not just one exam. It gives a big picture of your performance.
Every subject gets a grade (like A, B, C, etc.).
Each grade corresponds to a grade point (a number).
CGPA is the average of all these grade points for all subjects.
Full Form & Why It Matters
Full form: Cumulative Grade Point Average.
It matters because many schools, colleges or scholarship applications ask you to give your CGPA. It tells them how consistently you’ve done across all subjects.
How to Calculate CGPA
Here are the steps, simple:
Find out the grade point you got in each subject.
Add all those grade points together.
Divide by the number of subjects (or credit units, if your school uses credits).
The result is your CGPA.
Example:
| Subject | Grade Point |
|---|---|
| Subject 1 | 9 |
| Subject 2 | 8 |
| Subject 3 | 8 |
| Subject 4 | 7 |
| Subject 5 | 8 |
Add = 9 + 8 + 8 + 7 + 8 = 40
Number of subjects = 5
CGPA = 40 ÷ 5 = 8
Converting CGPA into Percentage
Many students want to know what their CGPA means as a percentage. Schools often use a simple formula for this. One popular method in India is:
Percentage = CGPA × 9.5
So, using our example above, where CGPA = 8:
Percentage = 8 × 9.5 = 76%
Keep in mind: some boards or institutions may use different multipliers or formulas. But 9.5 is commonly used.
Grade Points / Grading Scale
Grade points are assigned based on marks (out of 100). Different boards might change the ranges a bit. Here’s one common scale:
| Marks Range | Grade | Grade Point |
|---|---|---|
| 91-100 | A1 | 10 |
| 81-90 | A2 | 9 |
| 71-80 | B1 | 8 |
| 61-70 | B2 | 7 |
| 51-60 | C1 | 6 |
| 41-50 | C2 | 5 |
| 33-40 | D | 4 |
| Below 33 | E / Fail | 0-3 depending on the board |
Benefits & Limitations of the CGPA System
Benefits
It often reduces stress because small differences in raw marks (like 90 vs 99) don’t matter as much if both fall in the same grade bracket.
Gives you a “big picture” of how you’re doing—where you are strong, where you can improve.
Easier to compare academic performance over time.
Limitations
You may not know exactly how many marks you missed or got, only grade bands.
Sometimes it may feel like someone who got 99 marks and someone who got 90 marks look the same if both got the same grade, which can seem unfair.
Different schools might use different grading systems, so conversion to a percentage may vary.

Tips When Using CGPA & Percentage
Always check with your school or board what multiplier is used for conversion. It may not always be 9.5.
Keep your grade cards handy so you can see grade points per subject.
If your school uses credit hours (some do in higher education), you may need to multiply grade points by credit hours for each subject before averaging.

Conclusion
CGPA is a useful way to see how well you are doing overall—not just in one test. Converting it to a percentage helps compare with older systems or when applying somewhere that needs percentage scores. Just remember: know the formula your school uses, do the math right, and you’ll understand exactly what your CGPA means.
