Percentage & Marks Calculator

Calculate marks as a percentage, a percentage of an amount, or percentage change between two values.

How it works

Marks percentage = marks obtained ÷ total marks × 100. A result of 425 out of 500 is 85%.

Percentage change = (new − old) ÷ |old| × 100. This tool does not determine grades, eligibility or board-specific rounding rules.
