What is CGPA (Cumulative Grade Point Average)?

CGPA is a grading system used in many educational institutions to evaluate a student’s overall performance.

Instead of giving marks in percentage, universities convert performance into grade points like A, B, C, etc. These grade points are then averaged to calculate CGPA.

CGPA is usually measured on a scale of:

• 4.0 scale (common in USA, Canada)
• 5.0 scale (some Asian countries)
• 10.0 scale (India, Pakistan, and others)

What is CGPA Calculator?

A CGPA Calculator is an online or offline tool that automatically calculates your cumulative grade point average based on:

• Subject grades
• Credit hours
• Semester results
• GPA of each term

Instead of doing manual calculations, students enter their data, and the calculator instantly shows CGPA.

How CGPA is Calculated (Step-by-Step Explanation)

CGPA is calculated by dividing total grade points by total subjects or credit hours.

Basic Formula:

$\text{CGPA} = \frac{\sum (Grade\ Points)}{Number\ of\ Subjects}$CGPA=Number of Subjects∑(Grade Points)​

Step-by-Step Method:

Step 1: Convert Grades into Grade Points

Each subject grade is converted into numerical points.

Example:

• A = 10
• B = 8
• C = 6
• D = 4

Step 2: Multiply by Credit Hours

Each subject has credit hours. Multiply grade points by credit hours.

Step 3: Add All Values

Sum all weighted grade points.

Step 4: Divide by Total Credit Hours

Final result is your CGPA.

Difference Between GPA and CGPA

Many students get confused between GPA and CGPA.

Feature	GPA	CGPA
Full Form	Grade Point Average	Cumulative Grade Point Average
Duration	One semester	Entire course
Calculation	Subject-wise	Overall performance
Use	Semester result	Final academic record

How CGPA Calculator Works Online

An online CGPA calculator works using programming logic:

1. User inputs grades
2. System converts grades into points
3. Multiplies with credit hours
4. Adds total values
5. Divides by total credits
6. Displays final CGPA

Example of CGPA Calculation

Let’s understand with an example:

Subjects:

Subject	Grade	Grade Points	Credit Hours
Math	A	10	3
English	B	8	3
Physics	A	10	4
Chemistry	B	8	4

Step 1: Multiply

• Math = 10 × 3 = 30
• English = 8 × 3 = 24
• Physics = 10 × 4 = 40
• Chemistry = 8 × 4 = 32

Step 2: Add Total

30 + 24 + 40 + 32 = 126

Step 3: Total Credits

3 + 3 + 4 + 4 = 14

Step 4: CGPA

126 ÷ 14 = 9.0 CGPA
