Worked example

Starting from a percentage of 80%, the formula reverses to a CGPA of about 8.5 on the 10-point scale.

Why this is an estimate, not an official figure
A university issues your percentage from your actual CGPA, not the other way around — so reversing the formula recovers the CGPA that would produce that percentage. It matches in almost every case, but rounding on your transcript (for example a percentage printed to one decimal place) can shift the back-calculated CGPA slightly. When both numbers appear on your grade card, always quote the official CGPA rather than this estimate.
