What is a Percentage Calculator?

A Percentage Calculator is a versatile mathematical tool designed to solve a variety of problems involving percentages. It can perform three main types of calculations: finding a percentage of a number (e.g., what is 5% of 200?), determining what percentage one number is of another (e.g., 10 is what percent of 50?), and calculating the percentage increase or decrease between two numbers. It's a fundamental tool used in finance, shopping, academics, and everyday life.

How to Use the Percentage Calculator

Our calculator has three different tabs for each type of calculation. For example, to find a discount while shopping:

  1. Go to the 'X% of Y' tab.
  2. Enter the percentage and the number: To find a 20% discount on an item costing ₹2,500, you would enter '20' in the first box and '2500' in the second.

The calculator will instantly show you the result (e.g., ₹500), so you know the discount amount.
