What is CGPA?

It is an overall indicative percentage of marks.

How to calculate percentage from CGPA?

Multiply the CGPA with 9.5 or use the above calculator to get the indicative percentage.

The whole calculation is based on a formula which is tabled below and equipped with a simple input/output box so that anyone can calculate it easily. An indicative equivalence of Grade Point and Percentage of Marks can be assessed as follows:

  • Subject wise indicative percentage of marks = 9.5 x GP of the Subject.
  • Overall indicative percentage of marks = 9.5 x CGPA



Why multiply with 9.5 only?

The Board took the result of the 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.
