What is SGPA?

SGPA, or Semester Grade Point Average, is a grading system used in many Indian universities to assess a student’s academic performance. SGPA focuses solely on one semester. It is calculated by taking the weighted average of the grade points earned in all courses during a single semester.

Step-by-Step Guide to Calculating SGPA Manually

To calculate SGPA manually, you’ll need to follow a few simple steps:

  1. Understand the Grading System: 

Each university has a unique grading scale. In India, they range from 4 to 10. You must know the grading scale of your institution and how the grade points are allotted to the grades. 

  1. Identify Your Grades and Credit Points:

For calculating SGPA, you should know the exact grades for all the subjects that you have secured. Also check the corresponding grade points of your grading scale. 

  1. Multiply Grade Points by Credit Points:

For each course, multiply the grade points you earned by the course’s credit value. This gives you the weighted grade points for that course.

  1. Sum Up the Weighted Grade Points: 

Add all the weighted grade points from all your courses together.

  1. Calculate Total Credits: 

Add up all the credit points from your courses.

  1. Divide the Total Weighted Grade Points by Total Credits: 

Finally, divide the total weighted grade points by the total credits to get your SGPA.

Example Calculation

Let us understand it through an example:

CourseGradeGrade PointsCredit PointsWeighted Grade Points
Course 1A939 × 3 = 27
Course 2B848 × 4 = 32
Course 3C737 × 3 = 21
Course 4A929 × 2 = 18
  • Total Weighted Grade Points: 

27 + 32 + 21 + 18 = 98

  • Total Credits: 

3 + 4 + 3 + 2 = 12

  • SGPA: 

98 / 12 = 8.17

Why Calculate SGPA Manually?
