# How to Calculate Percentage? A percentage calculator is a handy tool that can be used to perform a wide range of calculations involving percentages. Whether you are a student trying to understand math concepts, a business professional looking to make financial projections, or simply someone who needs to perform basic math calculations in their daily life, a percentage calculator can be an invaluable resource.

So, what is a percentage calculator and how does it work? Essentially, it is a tool that allows you to input two numbers and determine the percentage of the first number that the second number represents. For example, if you wanted to know what percentage of 100 50 is, you would input 100 as the first number and 50 as the second number, and the calculator would tell you that 50 is 50% of 100.

There are many different ways in which a percentage calculator can be used. Some common examples include calculating discounts, determining the percentage change between two numbers, and finding the percentage of a total.

For instance, let's say you are shopping at a store and see that a shirt that normally costs \$50 is on sale for \$40. You can use a percentage calculator to determine how much of a discount this represents by inputting 50 as the first number and 40 as the second number. The calculator will tell you that the discount is 20%.

Similarly, if you are trying to determine the percentage change between two numbers, you can use a percentage calculator to quickly and easily do so. For example, let's say you want to know what percentage increase there was in the price of a particular item from one year to the next. You can input the price from the previous year as the first number and the price from the current year as the second number, and the calculator will tell you the percentage increase.

## Here are a few examples of how a percentage calculator can be used:

1. Calculating discounts: Imagine you are shopping at a store and see that a shirt that normally costs \$50 is on sale for \$40. You can use a percentage calculator to determine how much of a discount this represents by inputting 50 as the first number and 40 as the second number. The calculator will tell you that the discount is 20%.

2. Determining the percentage change between two numbers: Let's say you want to know what percentage increase there was in the price of a particular item from one year to the next. You can input the price from the previous year as the first number and the price from the current year as the second number, and the calculator will tell you the percentage increase.

3. Finding the percentage of a total: If you want to know what percentage of your monthly income goes towards rent, you can input your total monthly income as the first number and your rent as the second number, and the calculator will tell you what percentage of your income goes towards rent.

4. Calculating taxes: Let's say you want to know how much sales tax you will have to pay on a purchase. You can input the cost of the item as the first number and the sales tax rate as the second number, and the calculator will tell you the amount of sales tax you will have to pay.

5. Calculating grades: If you are a student and want to know what percentage of a test you got right, you can input the total number of questions on the test as the first number and the number of questions you answered correctly as the second number, and the calculator will tell you what percentage of the test you got right.

In summary, a percentage calculator is a useful tool that can be used for a variety of applications involving percentages. Whether you are a student, business professional, or just need to perform some basic math calculations, a percentage calculator can be a valuable resource.
