How to Calculate CGPA: Complete Step-by-Step Guide

Introduction

Many students want to know how to calculate CGPA because it plays an important role in academic performance, scholarships, internships, and university admissions. CGPA helps students understand their overall academic standing across multiple semesters or subjects.

Calculating CGPA is simple when you understand the formula and grading system used by your school or university. In this guide, you will learn the meaning of CGPA, how it is calculated, examples of CGPA calculations, and the difference between GPA and CGPA.

What Is CGPA?

CGPA stands for Cumulative Grade Point Average. It is the average of grade points earned in all semesters or courses over a complete academic program.

Unlike GPA, which measures performance for one semester, CGPA shows the overall academic performance throughout your studies.

Many educational institutions use CGPA systems on scales such as:

  • 4.0 scale
  • 5.0 scale
  • 10.0 scale

How to Calculate CGPA

To calculate CGPA, add the GPA or grade points of all semesters and divide the total by the number of semesters.

The CGPA formula is:

CGPA=GPA of All SemestersTotal Number of SemestersCGPA=\frac{\sum \text{GPA of All Semesters}}{\text{Total Number of Semesters}}CGPA=Total Number of Semesters∑GPA of All Semesters​

This formula gives the cumulative average performance across all semesters.

Step-by-Step Process to Calculate CGPA

Step 1: List All Semester GPAs

Write down the GPA obtained in each semester.

Example:

SemesterGPA
Semester 13.5
Semester 23.8
Semester 33.2
Semester 43.9

Step 2: Add All GPA Values

Add all semester GPAs together.

3.5+3.8+3.2+3.9=14.43.5+3.8+3.2+3.9=14.43.5+3.8+3.2+3.9=14.4

Step 3: Divide by Total Semesters

Divide the total GPA by the number of semesters.

CGPA=14.44=3.6CGPA=\frac{14.4}{4}=3.6CGPA=414.4​=3.6

The final CGPA is 3.6.

How to Calculate CGPA From Marks

Some schools and colleges provide marks or percentages instead of GPA. In that case, you first convert marks into grade points according to your institution’s grading system.

For example:

PercentageGrade Point
90–100%4.0
80–89%3.5
70–79%3.0
60–69%2.5

After converting percentages into grade points, calculate the average to get CGPA.

Difference Between GPA and CGPA

Students often confuse GPA and CGPA, but both are different.

GPA

GPA refers to the Grade Point Average for a single semester or term.

CGPA

CGPA represents the overall average GPA across all semesters combined.

For example:

  • GPA = performance in one semester
  • CGPA = overall performance during the entire degree

How to Convert CGPA Into Percentage

Different institutions use different conversion formulas. One common formula is:

Percentage=CGPA×9.5Percentage=CGPA\times9.5Percentage=CGPA×9.5

For example, if your CGPA is 8.2:

8.2×9.5=77.9%8.2\times9.5=77.9\%8.2×9.5=77.9%

So, the percentage is approximately 77.9%.

Always check your university’s official conversion formula because some institutions use different methods.
