Formula: CGPA = ฮฃ (SGPA ร Credits) / ฮฃ Credits
๐ Formula
CGPA = ฮฃ (SGPA ร Credits) / ฮฃ Credits- Enter the SGPA and total credits for each completed semester.
- Each semester’s SGPA is multiplied by that semester’s credits.
- The sum of these weighted values is divided by your total credits across all semesters.
- The result is your cumulative CGPA.
This is the standard method for converting multiple semester SGPAs into a cumulative CGPA: a credit-weighted average across every semester of your degree. Semesters with more credits contribute proportionally more to the final figure, which is exactly how universities compute the CGPA printed on your transcript.
๐ SGPA to CGPA
A common mistake is to simply add up all your SGPAs and divide by the number of semesters. That simple average is inaccurate whenever semesters carry different credit loads โ and in most degree programmes they do. A 24-credit semester should pull your CGPA more strongly than an 18-credit one, and only a weighted average captures that.
This converter does the weighting for you. Enter each semester’s SGPA alongside its credits, and the tool computes the true credit-weighted CGPA rather than a misleading arithmetic mean.
โ Frequently Asked Questions
Why not just average SGPAs?
Because semesters carry varying credit loads, a simple arithmetic mean gives the wrong answer โ credit-weighted averaging is required to match your official CGPA.
