What is CGPA?

Definition and Full Form of CGPA

CGPA (Cumulative Grade Point Average) is a grading system used in schools, colleges, and universities to evaluate a student’s overall academic performance. Instead of providing marks in absolute numbers, CGPA represents a student’s achievements in the form of a weighted average of grade points obtained in all subjects over a semester or academic year.

For example, if a student scores 8.5 CGPA, it means their average grade across all subjects is 8.5 on a scale of 10.

How CGPA Differs from GPA and Percentage

Factor	CGPA (Cumulative Grade Point Average)	GPA (Grade Point Average)	Percentage
Scope	Measures overall academic performance over multiple semesters or years	Measures performance for a single semester or term	Expresses performance as a percentage of total marks
Scale Used	Usually on a 10-point or 4-point scale	Generally on a 4-point scale (used in the US)	Calculated out of 100%
Usage	Used in India, CBSE, and universities	Common in foreign universities (US, UK, Canada, etc.)	Preferred in job applications and competitive exams
Conversion	Can be converted to percentage using specific formulas	Can be converted to CGPA using conversion charts	Can be converted to CGPA by dividing by a specific factor

Common Grading Systems in India (CBSE, Universities, etc.)

India follows different grading systems depending on the board or university:

1. CBSE (Central Board of Secondary Education) CGPA System

• CBSE introduced CGPA to replace the percentage system.
• Students are graded on a 10-point scale, with grade points assigned to each subject.
• The formula for CBSE CGPA to percentage conversion:
  Percentage = CGPA × 9.5

2. University CGPA System (DU, JNU, Mumbai University, etc.)

• Indian universities use different CGPA systems (4.0 or 10.0 scale).
• Some universities use a relative grading system, while others follow an absolute grading method.
• Formula for CGPA to percentage conversion varies depending on the university.

3. International Grading Systems (US, UK, Canada, Australia)

• United States: Uses GPA on a 4.0 scale.
• United Kingdom: Uses Class-based grading (First Class, Upper Second, etc.).
• Canada & Australia: Follow a mix of percentage-based and GPA systems.

Since different institutions and countries follow varying grading methods, students often need a CGPA Calculator to ensure accurate conversions for academic and job-related purposes.

How to Calculate CGPA?

Step-by-Step Explanation of the CGPA Calculation Formula

Calculating CGPA (Cumulative Grade Point Average) is simple if you follow the correct method. The formula used to calculate CGPA is:

$$CGPA = \frac{\text{Total Grade Points Obtained in All Subjects}}{\text{Total Number of Subjects}}$$

Example Calculation with Real Numbers

Let’s assume a student has five subjects, and their grade points for each subject are as follows:

Subject	Grade Point (GP)
Mathematics	8.5
Science	9.0
English	7.5
Social Science	8.0
Hindi	9.2

Step-by-Step Calculation:

1. Add all the grade points together: $$8.5 + 9.0 + 7.5 + 8.0 + 9.2 = 42.2$$
2. Divide by the total number of subjects: $$CGPA = \frac{42.2}{5} = 8.44$$

So, the student’s CGPA is 8.44.

Table: CGPA to Percentage Conversion (CBSE Formula)

CBSE follows a fixed formula to convert CGPA to percentage:

$$\text{Percentage} = CGPA \times 9.5$$

Here’s a quick conversion table:

CGPA	Percentage (%)
10.0	95.0
9.5	90.25
9.0	85.5
