About the CGPA Calculator

Enter each semester on its own line as SGPA and credits, for example “8.4 22”. The calculator gives your CGPA and the equivalent percentage under the two most common conversion rules.

CGPA is the credit-weighted average of all semesters, so a semester with more credits counts for more. If every semester carries the same credits, it's a plain average of the SGPAs, and you can enter just the SGPAs.

The formula

CGPA = Σ(SGPA × semester credits) ÷ Σ credits

SGPA: semester grade point average, on a 10-point scale
credits: total credits for that semester

Worked example

Four semesters: 8.4 (22 credits), 8.9 (24), 7.8 (21), 9.1 (23)

Weighted total: 184.8 + 213.6 + 163.8 + 209.3 = 771.5
Credits: 22 + 24 + 21 + 23 = 90
CGPA = 771.5 ÷ 90 = 8.57, about 81.4% with the ×9.5 rule

Things to keep in mind

Universities differ in how they handle failed or repeated courses; follow your university's rules for those semesters.
