What is CGPA? 

CGPA stands for Cumulative Grade Point Average. It is a method used by educational institutions to measure a student’s overall academic performance. Unlike a single subject score, the CGPA is a cumulative measure that takes into account all the courses you have studied over a specified period.

CGPA is calculated by summing up the grade points obtained in all subjects and dividing by the total number of subjects or credits. This number is typically expressed on a scale (for example, 0.0 to 10.0 or 0.0 to 4.0) and provides a snapshot of your academic progress.

Key Points:

• Definition: CGPA is the overall average of grade points earned.
• Usage: Commonly used in high schools, colleges, and universities.
• Purpose: Helps in assessing overall academic performance.

Understanding what is CGPA is the first step toward grasping your academic standing and planning improvements in your studies.

Difference Between CGPA, SGPA, and GPA

Although these phrases are commonly used interchangeably, there are some differences. 

• SGPA (Semester Grade Point Average):
  The SGPA is calculated at the end of each semester.It reflects your performance in that particular term.
• GPA (Grade Point Average):
  GPA is often used in schools and colleges to indicate performance in a single term or year. It might be calculated for a specific semester or subject combination.
• CGPA (Cumulative Grade Point Average):
  CGPA is the average of all the SGPAs (or GPAs) over the entire course duration. It gives a holistic picture of your academic performance.

Quick Comparison:

• SGPA: Focuses on one semester.
• GPA: Can refer to a term-wise performance.
• CGPA: Overall performance across all terms.

Knowing these differences is essential as many institutions use CGPA to determine academic success and for admissions to higher studies or jobs.

How to Calculate CGPA: Step-by-Step Guide 

Now, let’s dive into the process of calculating your CGPA. The following steps will help you learn how to calculate CGPA accurately.

Understanding the CGPA Formula 

The most common formula for calculating CGPA is:

CGPA = Total Grade Points Total Credits

Where:

• Total Grade Points is the sum of the grade points earned in all subjects.
• Total Credits is the sum of the credit values assigned to each subject.

For schools or boards that use a simple average, the formula might be:

CGPA = Sum of All Grade Points Number of Subjects

For example: CGPA = 114 14 ≈ 8.14

Example Calculation 

Consider a student who has received the following grade points in five subjects:

Subject	Grade Points (GP)	Credits
Mathematics	9	4
Science	8	3
English	7	2
History	8	3
Geography	8	2

Step 1: Multiply grade points by credits for each subject:

• Mathematics: 9×4=36
• Science: 8×3=24
• English: 7×2=14
• History: 8×3=24
• Geography: 8×2==16

Step 2: Calculate the total grade points:

Total Grade Points = 36 + 24 + 14 + 24 + 16 =114

Step 3: Calculate the total credits:

Total Credits 4+3+2+3+2=14

Step 4: Divide the total grade points by total credits:

CGPA = Sum of All Grade Points Number of Subjects

For example: CGPA = 114 14 ≈ 8.14

Thus, the student’s CGPA is approximately 8.14.

How to Calculate CGPA from Marks 

Many educational boards, such as CBSE, use a system where marks are converted into grade points before calculating the CGPA. Here’s a simplified approach to calculate CGPA from marks:

1. Convert Marks to Grade Points:
   Each board or institution provides a grade table that converts marks into a corresponding grade point. For example, if the grading scale is from 1 to 10, you might have a conversion like:
   • 91-100 marks = 10 grade points
   • 81-90 marks = 9 grade points
   • 71-80 marks = 8 grade points, and so on.
2. Calculate the Grade Point for Each Subject:
   For each subject, determine the grade point using the provided table.
3. Apply the CGPA Formula:
   Sum all the grade points and divide by the number of subjects or total credits, as described earlier.

Example Using Marks:

Suppose a student gets the following marks and corresponding grade points:

Subject	Marks	Grade Points (GP)
Mathematics	95	10
Science	88	9
English	76	8
History	85	9
Geography	82	9

Step 1: Sum of Grade Points:

Total Grade Points=10+9+8+9+9=45

Step 2: Number of Subjects:
There are 5 subjects.

Step 3: Calculate CGPA:

CGPA = Total Grade Points Total Credits

For example: CGPA = 45 5 = 9.0

Thus, the CGPA of the student is 9.0.

CGPA to Percentage Conversion 

In many cases, especially for admissions to universities abroad, you may need to convert your CGPA to a percentage. The conversion formula may vary depending on the institution, but a common method used by the CBSE is:

Percentage = CGPA × 9.5

Example Conversion:

If a student’s CGPA is 8.14, then the percentage is calculated as:

Percentage = 8.14 × 9.5 ≈ 77.33%

Thus, the student’s overall percentage is around 77.33%.

Using a CGPA Calculator 

For convenience, many students use an online CGPA calculator. These tools allow you to input your marks, credits, and grade points, and they automatically calculate your CGPA and even convert it to percentage.

Benefits of a CGPA Calculator:

• Time-Saving: Quickly calculate CGPA without manual computation.
• Error Reduction: Minimizes mistakes in calculations.
• Easy Conversion: Automatically converts CGPA to percentage.
• User-Friendly: Often designed with simple interfaces suitable for students of all levels.

  The conversion of marks to grade points can sometimes distort the actual performance.
• Variation in Conversion Scales:
  Different institutions may use different scales, making standardization a challenge.
