# How Do we Calculate Percentage?

Calculating percentage can be a useful skill in a variety of situations, whether you’re trying to find out what grade you got on a test or trying to determine what discount you can get on a purchase. In this article, we’ll explain the basic steps for calculating percentage and provide some examples to help you understand how it works.

**To calculate percentage, you’ll need to know the following three pieces of information:**

**The base:** This is the number that you’ll be taking a percentage of. For example, if you want to find out what percentage of your total expenses went towards rent, the base would be the total amount you spent on expenses.

**The rate: **This is the percentage that you’re interested in finding out. For example, you might want to know what percentage of your total expenses went towards rent, so the rate would be the percentage of your expenses that went towards rent.

**The result: **This is the number you’ll get when you calculate the percentage. In the example of finding out what percentage of your total expenses went towards rent, the result would be the percentage of your expenses that went towards rent.

**To calculate percentage, you’ll need to use the following formula:**

(Rate / Base) x 100 = Result

Let’s look at an example to see how this formula works.

**Example:** You have a total of $1,000 in expenses for the month, and $200 of that went towards rent. What percentage of your expenses went towards rent?

**To solve this problem, we’ll plug the numbers into the formula like this:**

(200 / 1000) x 100 = 20

This means that 20% of your expenses went towards rent.

**Here’s another example:**

**Example:** You got a score of 80 out of 100 on a test. What percentage did you get on the test?

**To solve this problem, we’ll plug the numbers into the formula like this:**

(80 / 100) x 100 = 80

This means that you got an 80% on the test.

As you can see, calculating percentage is a relatively simple process that just requires you to have the base, rate, and result. Once you have those three pieces of information, you can use the formula to find out the percentage. Whether you’re trying to figure out what grade you got on a test or what discount you can get on a purchase, knowing how to calculate percentage can be a useful skill to have.
