What Is This Tool About?

What is CGPA and how does it work?

CGPA (Cumulative Grade Point Average) is a grading system used to measure overall academic performance. It represents the average of grade points obtained in all subjects over a period of time.

Instead of marks, each subject is assigned a grade point. These points are averaged to calculate the CGPA.

How CGPA is calculated

  • Each subject is assigned grade points
  • Each subject has credit weight
  • Grade points are multiplied by credits
  • Total is divided by total credits

This gives your final CGPA.

Example to calculate CGPA

Suppose you have grades: 8, 9, 7, 10, and 9. Each subject has equal credit.

Step-by-step

  1. Total = 8 + 9 + 7 + 10 + 9 = 43
  2. Divide by number of subjects (5)
  3. CGPA = 43 ÷ 5 = 8.6

How to convert CGPA to percentage

The conversion depends on your institution, but the most commonly used formula is:

Percentage = CGPA × 9.5

Example

If CGPA = 8.2, then Percentage = 8.2 × 9.5 = 77.9%.
