What are percentages?

A percentage shows a number as a part of 100. It is a simple way to describe how much of something you have compared to the whole. We write percentages with the “%” symbol. For example, if a garage has 100 cars and 25 are white, then 25% of the cars are white.

How to calculate a percentage

To calculate a percentage, divide the part by the whole, then multiply by 100. This formula turns the result into a number between 0 and 100. For example, if you have 50 apples and 20 are red, you divide 20 by 50 to get 0.4. Multiply by 100, and the answer is 40%. This Percentage Calculator makes this process fast and removes the chance of mistakes.

Why percentages matter

Percentages appear in many areas of daily life. You see them in discounts, taxes, loan rates, and tips. Businesses use percentages to measure profit margins, market changes, and growth rates. Understanding percentages and using this percentage calculator can help you make smarter decisions with money, data, and comparisons.

Percentage change from A to B

Let’s say you follow a company’s stock price. Last year, the stock traded at $48. This year it trades at $61. Entering “from 48 to 61” shows the percentage change. The calculator reports a 27.1% increase. If the price had dropped instead, it would display the correct percentage decrease.
