Percentage Calculator

Marks to percentage, X% of a number, % change, and CGPA to percentage for CBSE, VTU and more.

This calculator does both: turn marks into a percentage, convert CGPA to percentage with the formula your board or university uses, or work out everyday percentages such as a discount or a salary hike.
