How to Calculate CGPA? Step-by-Step Guide with Formula & Examples

CGPA (Cumulative Grade Point Average) is calculated by taking the average of GPA scores across all semesters. It gives an overall view of your academic performance.

CGPA Formula

CGPA = Total GPA of All Semesters ÷ Number of Semesters

This formula is simple: add your GPA from each semester and divide by the total number of semesters.

Step-by-Step CGPA Calculation

1. Collect GPA scores for all semesters
2. Add all GPA values
3. Divide by the number of semesters

Example of CGPA Calculation

Let’s calculate CGPA for a student with the following GPA scores:

• Semester 1: 8.2
• Semester 2: 7.8
• Semester 3: 8.5
• Semester 4: 9.0

Step 1: Add GPA values
= 8.2 + 7.8 + 8.5 + 9.0 = 33.5

Step 2: Divide by total semesters
= 33.5 ÷ 4

CGPA = 8.37

How to Calculate CGPA from Marks

In some cases, you may only have marks or percentages. You need to convert them into GPA first, then calculate CGPA.

• Convert marks into grade points (based on your institution scale)
• Calculate GPA for each semester
• Apply CGPA formula

CGPA to Percentage Conversion

To convert CGPA into percentage (commonly used in India):

Percentage = CGPA × 9.5

Example: If CGPA = 8.37
Percentage = 8.37 × 9.5 = 79.51%

Tips to Improve CGPA
