How to Calculate Percentage from CGPA?

To convert CGPA into percentage, multiply the CGPA with 9.5 to get the overall indicative percentage. Now students might thought, why multiply with 9.5 only. Your senior toppers of CBSE board have contribution in it. Here’s why. The Board analyzed the result of last five years and calculated the average marks of all candidates who had scored between 91 and 100. That average turned out to be close to 95 marks. Since the equivalent Grade Point for the 91-100 band (A1 grade) of marks is 10, it then divided the average result of 95 by 10. The result is 9.5.

The board disclaims that the percentage is only an approximation and not exact percentage.

To understand it in a better way, let’s take an example to convert CGPA to GPA:

Suppose the student scored

Subject 1 – 9

Subject 2 – 10

Subject 3 – 9

Subject 4 – 7.5

Subject 5 – 8

So, now the sum of the Grade Points (GP) will be : 9+8+7.5+9+10 = 43.5

Dividing the sum with 5 will be 43.5 / 5 = 8.7

8.7 is the CGPA of the student.

To find out the approximate percentage, multiply the CGPA with 9.5

that is, 9.7 x 9.5 = 82.65%

So, the approximate percentage obtained by a student is 82.65%.

How to Convert CGPA to Percentage?

So an indicative equivalent percentage of the grade point can be calculated as:

Subject wise percentage = Grade point (GP) obtained by the student x 9.5

And the overall percentage of marks = 9.5 x CGPA
