CGPA to percentage: the formula for your board or university

Application forms keep asking for a percentage when your grade card shows a CGPA. There's no single formula: it depends on who awarded the grade. Here's how to get it right.

Why it happens

1. Each board and university has its own formula

CBSE uses CGPA × 9.5. VTU uses (CGPA − 0.75) × 10. Anna University uses CGPA × 10. Using the wrong one can change your percentage by several points.

2. Your grade card is the final word

Many universities print the official conversion on the grade card or transcript. If it's there, use that formula.

3. Some institutes don't convert at all

Several IITs and other institutes don't define a percentage. If a form insists, write the CGPA and its scale (for example 8.4/10) and note that no official conversion exists.
