Anna University CGPA & Percentage Calculator: how it works

Anna University converts CGPA to percentage by a direct multiplication by ten. Here is how the CGPA itself is built from your credits and grades.

The conversion formula

Percentage = CGPA × 10

Applies to Regulation 2017 and 2021 schemes

Anna University applies no deduction before scaling, unlike VTU and KIIT. A CGPA of 8.5 is 85 percent, straightforwardly.

How CGPA is calculated from grades

CGPA = Σ(Grade point × Credits) ÷ Σ(Credits)

This is a credit-weighted average, not a simple mean of your grades. A four-credit core subject moves your CGPA twice as much as a two-credit elective with the same grade.
