How is CGPA Calculated and Converted to Percentage in India?
CGPA stands for Cumulative Grade Point Average. This is a grading system used in many Indian schools, colleges, and universities to measure a student's overall academic performance. Unlike marks or percentages, CGPA summarizes your achievement as a single number, making it easier to compare and understand progress across terms or years.
The CGPA system replaces long lists of subject-wise marks with a standardized score, usually calculated on a scale such as 10, 5, or 4 points, depending on the education board or institution. Its primary goal is to offer a simple overview of your academic standing, reducing the stress and variability of raw marks.
Understanding CGPA: What Does it Mean?
CGPA gives you a quantitative summary of your learning across several subjects over an academic session. For each subject, you receive a grade point based on your performance.
To calculate your CGPA, grade points from individual subjects are averaged. The result is your cumulative score for that term or course.
CGPA can be found on your report card or marksheet from school or college. It is especially common in results of board exams and university records.
Many educational institutions use CGPA instead of percentages to assess eligibility for higher education, scholarships, or jobs.
How is CGPA Calculated?
- Each subject you take is assigned a grade point based on your marks.
- Every subject also has “credit points” to reflect its importance or study hours.
- Multiply your grade point by the credit points for each subject to get “weighted grade points”.
- Add up all the weighted grade points across subjects.
- Divide the total weighted grade points by the sum of all credits. The answer is your CGPA.
For example, if your grade points for five equally-weighted subjects are 8, 9, 7, 10, and 9, then your CGPA is (8+9+7+10+9)/5 = 8.6.
CGPA to Percentage: Conversion Method
Many institutions, such as schools or boards, require CGPA to be converted into percentage for admissions or eligibility.
To do this, a standard method is used:
- For CGPA on a 10-point scale: Multiply your CGPA by 9.5.
Example: If your CGPA is 8.2, then percentage = 8.2 × 9.5 = 77.9%. - For other scales (4 or 5): Refer to specific conversion charts provided by your institution, as shown below.
