With equal-credit semesters, CGPA is the average of your SGPAs. Add per-semester credits to weight them. The percentage shown uses the common CBSE-style ×9.5 rule; your institution's factor may differ.
CGPA (Cumulative Grade Point Average) is your overall grade-point average across every semester. When each semester carries the same credits, CGPA is the average of your semester SGPAs; when credits differ, each SGPA is weighted by that semester's credits. Enter your SGPAs above (and credits if needed).
Four semesters at 8.2, 7.8, 8.5 and 9.0 (equal credits): (8.2+7.8+8.5+9.0) ÷ 4 = 8.38 CGPA. As a CBSE-style percentage: 8.38 × 9.5 = 79.56%.

Many Indian boards and universities convert CGPA to a percentage by multiplying by 9.5 (the CBSE rule), though some use a different factor. Use our CGPA to percentage calculator for your specific board.
