CGPA Calculation Methods & Backend Logic

Standard CGPA Formula

CGPA = Σ(Grade Points × Credit Hours) / Σ(Credit Hours)

Sum of (Grade Points multiplied by Credit Hours) divided by Total Credit Hours

Step-by-Step Process:

1

Convert letter grades to grade points

Using the selected grading scale (4.0, 4.3, or 10.0)

2

Multiply by credit hours

Grade points × credit hours for each course

3

Sum all quality points

Add all (grade points × credit hours) values

4

Divide by total credit hours

Final CGPA = Total quality points ÷ Total credits

Practical Example

Sample Calculation (4.0 Scale):

Semester 1 Courses:
Mathematics (A) - 4 credits:4.0 × 4 = 16.0
Physics (B+) - 3 credits:3.3 × 3 = 9.9
Chemistry (A-) - 3 credits:3.7 × 3 = 11.1
English (B) - 2 credits:3.0 × 2 = 6.0
Total Quality Points:43.0
Total Credit Hours:12
CGPA:43.0 ÷ 12 = 3.58

Advanced Features:

  • Cumulative Tracking: Maintains running CGPA across all semesters
  • Semester GPA: Individual semester performance calculation
  • Credit Weighting: Properly weights courses by credit hours
  • Scale Conversion: Automatic conversion between different scales
  • Performance Analytics: Trends and improvement tracking
