How to Calculate CGPA - Complete Guide
Learn how to calculate CGPA (Cumulative Grade Point Average) step by step. This comprehensive guide covers all methods, formulas, and examples for calculating CGPA in Indian universities.
Quick CGPA Calculator
Method 1: Simple Average Method
Formula
CGPA = (GPA₁ + GPA₂ + GPA₃ + ... + GPAₙ) ÷ Number of Semesters
Step-by-Step Process:
- Calculate GPA for each semester
- Add all semester GPAs together
- Divide the sum by total number of semesters
Example:
Semester GPAs: 8.5, 7.8, 8.2, 9.1
CGPA = (8.5 + 7.8 + 8.2 + 9.1) ÷ 4
CGPA = 33.6 ÷ 4 = 8.4
Method 2: Credit-Weighted Method
Formula
CGPA = Σ(GPA × Credits) ÷ Total Credits
Step-by-Step Process:
- Multiply each semester GPA by its credit hours
- Add all the products from step 1
- Divide by total credit hours of all semesters
Example:
Semester 1: GPA 8.5, Credits 20 → 8.5 × 20 = 170
Semester 2: GPA 7.8, Credits 22 → 7.8 × 22 = 171.6
Semester 3: GPA 8.2, Credits 21 → 8.2 × 21 = 172.2
Semester 4: GPA 9.1, Credits 23 → 9.1 × 23 = 209.3
CGPA = (170 + 171.6 + 172.2 + 209.3) ÷ (20 + 22 + 21 + 23) = 723.1 ÷ 86 = 8.41
How to Calculate CGPA from SGPA
SGPA (Semester Grade Point Average) is the GPA for individual semesters. To convert SGPA to CGPA:
SGPA to CGPA Formula
CGPA = (SGPA₁ + SGPA₂ + ... + SGPAₙ) ÷ n
Example:
SGPA values: 8.2, 7.9, 8.5, 8.8, 9.0, 8.3
CGPA = (8.2 + 7.9 + 8.5 + 8.8 + 9.0 + 8.3) ÷ 6
CGPA = 50.7 ÷ 6 = 8.45
