What is a Percentage?

A percentage is a way of expressing a number as a part of a whole, specifically out of 100. When you see a percentage, it essentially tells you how many parts of a whole are represented by a certain amount. For instance, 50% means 50 out of 100, or half of a given amount.

Percentages are used widely in finance, statistics, data analysis, and even in our daily lives when calculating discounts, interests, grades, and more. The concept is simple: if you want to know what part of a certain number is relative to another, a percentage can give you an easy way to understand it.

How to Calculate Percentages?

Calculating a percentage can be done by using a straightforward formula:

Percentage=(PartWhole)×100\text{Percentage} = \left(\frac{\text{Part}}{\text{Whole}}\right) \times 100Percentage=(WholePart​)×100

In our example, the “part” is 551.21, and the “whole” is 725. By placing these numbers into the formula, we can find out what percentage 551.21 is of 725.
