Frequently Asked Questions
CGPA (or SGPA) is the credit-weighted average of grade points. Formula: CGPA = Sum of (Grade Point × Credit) for all subjects, divided by the Total Credits. For example, two subjects with grade points 9 and 8, both 4 credits: (9×4 + 8×4) / 8 = 8.5.
The most common formula, used by CBSE, is Percentage = CGPA × 9.5. For example, a CGPA of 8.2 equals 8.2 × 9.5 = 77.9%. Some universities use a different multiplier or formula, so the tool lets you pick 9.5, 10, or a custom multiplier.
SGPA (Semester Grade Point Average) is calculated for a single semester from that semester's subjects. CGPA (Cumulative Grade Point Average) combines all semesters. You can find CGPA by averaging the SGPA of every semester.
If every semester carries the same total credits, CGPA is simply the average of all semester SGPAs. Use the "SGPA → CGPA" mode, enter each semester's SGPA, and the tool averages them automatically.
It uses the standard 10-point grading scale used by most Indian universities (O = 10, A+ = 9, A = 8, B+ = 7, B = 6, C = 5, P = 4, F = 0). Enter the grade point for each subject directly along with its credits.
