What Is SGPA?

The full form of SGPA is Semester Grade Point Average. SGPA a measure of academic performance in a specific semester. In simple terms, it reflects how well a student has performed in a particular set of courses within a single semester. SGPA is calculated by assigning grade points to the letter grades obtained by the student in each course and then taking the weighted average.

How Is SGPA Calculated?

The formula for calculating SGPA is:
SGPA= ∑(Credits × Grade Points)​/ ∑Credits


  • Credits = Credits assigned to the course
  • Grade Points = Points corresponding to the grade obtained in the course

What Is CGPA?

This table provides a comprehensive difference between CGPA and SGPA, including their scope, calculation methods, acceptance criteria, and calculation characteristics. Moving ahead to explore the process for calculating these with an example.

How to Calculate SGPA and CGPA with Example? 

Let’s go through the steps to calculate SGPA (Semester Grade Point Average) and CGPA (Cumulative Grade Point Average). The SGPA calculation Vs. CGPA calculation is also explained with an example:

Step 1: Understand the Grading System: 

Before calculating SGPA and CGPA, it's essential to understand the grading system used by your educational institution. For this example, let's assume we're using a 4-point grading scale, where grades are assigned as follows:

  • A = 4.0
  • B = 3.0
  • C = 2.0
  • D = 1.0
  • F = 0.0

Step 2: Calculate SGPA :

SGPA is calculated for a single semester by averaging the grade points earned in all courses, weighted by the credits for each course. Here's an example:

  • Course 1: Grade B (3.0), Credits 3
  • Course 2: Grade A (4.0), Credits 4
  • Course 3: Grade C (2.0), Credits 3

To Calculate SGPA:

Multiply each grade by its respective credit:

  • Course 1: 3.0 (grade) * 3 (credits) = 9.0
  • Course 2: 4.0 * 4 = 16.0
  • Course 3: 2.0 * 3 = 6.0
  • Add up the total grade points earned: 9.0 + 16.0 + 6.0 = 31.0
  • Add up the total credits: 3 + 4 + 3 = 10
  • Divide the total grade points by the total credits: 31.0 / 10 = 3.1

So, the SGPA for this semester is 3.1.

Step 3: Calculate CGPA:

CGPA is the average of all SGPA's earned across multiple semesters, weighted by the respective credits for each semester. Let's say we have SGPA's for three semesters:

  • SGPA Semester 1: 3.0
  • SGPA Semester 2: 3.2
  • SGPA Semester 3: 3.1

To calculate CGPA:

  • Add up all the SGPA's: 3.0 + 3.2 + 3.1 = 9.3
  • Divide the total SGPA by the number of semesters: 9.3 / 3 = 3.1

So, the CGPA for these three semesters is 3.1.

This example demonstrates the step-by-step calculation of and  SGPA and CGPA difference using a 4-point grading scale. Make sure to adapt the calculations based on the grading scale and credit system used by your educational institution.
