How to Use the Percentage Calculator
This tool has three modes. Use "X% of Y" to find a percentage of a number (e.g. 20% of 500 = 100). Use "X is what % of Y" to find your exam percentage — just enter your marks and total marks. Use "% Change" to see how much something increased or decreased.
The most common use for students is calculating exam scores: enter your marks obtained as X and total marks as Y to instantly see your percentage grade.
