How To Calculate CGPA From Marks: A Step-by-Step Guide (2023)

In this article, we will know about how to calculate CGPA from marks

CGPA stands for Cumulative Grade Point Average shows a student’s academic performance. It provides detailed information about students’ overall grades in different subjects and semesters. CGPA is used in various educational institutions globally, and understanding how to accurately calculate it is very important for students as well as educators. In this article, you will be guided step-by-step through the process of calculating CGPA from marks, taking the standard 4.0 scale into account.

Understanding Grading System

Before diving into the calculation process, it is crucial to understand the 4.0 grading system used in your institution. In this system, the grades are given as follows:

Marks/Percentage(%)Grade Point Average ( GP)Letter Grade
90 and above4A+
75-803.7 B+

For instance, if you scored 85% in Computer Science, your GPA for that subject would be 3.9.

Step-by-Step Calculation

Follow these methods to determine your CGPA from grades using the 4.0 grading system:

Step 1: Obtain the Grade Points for Each Subject

First of all, you need to find the grade point (GP) corresponding to the marks obtained in each subject, based on a 4.0 grading scale that was previously provided above.

Step 2: Calculate Total Credit Points

The next step is to figure out the credit points for each subject. Credit points usually indicate the weightage of a subject based on the number of hours it is taught each week. This step can be skipped, if your institution follows such a Grade Point system where all subjects have equal credits because the credit point would be the same for all subjects.

Step 3: Multiply Grade Points by Credit Points

Now, the Grade Points which are obtained in Step 1 multiply it with the corresponding Credit Points for each subject. As a result, it will give you the Total Quality Points ( TQP ) for each subject.

Subject 1 ( TQP ) = GP of subject 1 * Credit Points of subject 1

Subject 2 ( TQP ) = GP of subject 2 * Credit Points of subject 2

……… and so on

Subject n ( TQP ) = GP of subject n * Credit Points of subject n

Step 4: Calculate Total Credit Points Earned ( TCPE )

Now find the total Credit Points by adding all the Credit Points earned across all subjects. As a result, it will give you the Total Credit Points Earned ( TCPE ).

Total Credits Points Earned (TCPE ) = Subject 1 Credit Points +Subject 2 Credit Points+…+Credit Points Subject n

Step 5: Calculate CGPA

The Total Quality Points (TQP) are divided by the Total Credit Points Earned (TCPE) to determine the cumulative Grade Point Average (CGPA).

CGPA = Total Quality Points (TQP) / Total Credit Points Earned (TCPE)

Congratulations! Using the 4.0 grading scale, you have now calculated your CGPA from the marks you obtained in the individual subject.


The CGPA is an important metric that shows a student’s overall academic performance in a detailed manner. By following the above-mentioned steps and fully understanding the 4.0 grading system, you can perfectly calculate your CGPA. It is crucial to monitor your academic progress because it might have a big impact on your future educational options and employment chances. Always put forth consistent effort and attention to your studies for better CGPA results.
