What is the CGPA Calculator?
CGPA (Cumulative Grade Point Average) is a metrics system used by schools and universities worldwide to measure a student's overall academic performance. Unlike GPA, which focuses on a single semester, CGPA weights your grade points across all semesters and credits completed.
Our free CGPA calculator eliminates manual spreadsheet errors by weighting your grades based on course credits automatically. We use the standard 10-point grade scale widely adopted in global universities, and provide conversion estimates to percentage based on standard multipliers.
