What is CGPA and How is It Calculated?
CGPA (Cumulative Grade Point Average) is the overall average of grade points earned in all semesters, weighted by the number of credits for each subject. Indian universities switched from a percentage-based system to CGPA to align with international standards and to give more nuanced performance measurement.
On a 10-point scale, grades are mapped as follows: O (Outstanding) = 10, A+ = 9, A = 8, B+ = 7, B = 6, C = 5, P (Pass) = 4, F (Fail) = 0. To convert CGPA to percentage, CBSE recommends multiplying by 9.5. For example, a CGPA of 8.5 equals 80.75%. However, different universities use different multipliers — VTU uses CGPA × 10 − X, Anna University uses direct percentage calculation.
CGPA is important for graduate school applications, campus placements, and government jobs. Most PSU recruitments require a minimum CGPA of 6.5/10. IITs and NITs require a CGPA of 7.5+ for PhD admissions.
