What is a Percentage Calculator?
A Percentage Calculator is a digital tool that automates percentage-related calculations. Instead of doing the math manually, this tool instantly computes results for three main types of percentage operations:

Example: What is 25% of 200? - What is the percentage change from X to Y?
Example: How much is the increase from 50 to 75 in percentage? - X is what percent of Y?
Example: 40 is what percent of 200?
It helps users save time, avoid manual errors, and understand percentage relationships more intuitively.
