What Is a Percentage Calculator?
A Percentage Calculator is a tool that helps you find percentage relationships between numbers. Instead of figuring it out manually, this calculator handles:
Finding a % of a number (e.g., 20% of 150)

Percentage increase or decrease
By entering the correct numbers, the tool will compute your desired percentage result instantly.
Example Calculations

If you want to know what percent 30 is of 120, enter: Part = 30, Whole = 120 → Result = 25%
For percentage change: Old value 100, New value 125 → increase is 25%
