In this post, we will talk about what is a percentage, the percentage formula, how to calculate percentage, for exam marks, in excel, in the calculator, and many other questions related to percentage.

Percentage

A percentage is a form of expressing a number as a fraction of 100. It is calculated by dividing the number by 100 and multiplying the result by 100.

For example, if someone has a score of 85 out of 100 on an exam, their percentage would be 85/100 x 100 = 85%.

What is Percentage Formula?

The percentage formula is % = (number/total) x 100. In other words, to calculate a percentage, divide the number you want to find the percentage of by the total and multiply by 100.

For example, if you wanted to know what percentage 75 is of 250: (75/250) x 100 = 30%.

How to Calculate Percentage?

There are many ways to find percentages.

  • The most common way is called the percentage formula, which consists in dividing the number you want to find the percentage of by the total and multiplying by 100.

For example, if you wanted to know what percentage 75 is of 100: (75/100) x 100 = 75%.

  • Another way to calculate a percentage is by using a calculator. Simply enter the number you want to find the percentage of, divide it by 100 and press the % button.

For example, to find what percentage 97 is of 100: 97/100 = 0.97 x 100 = 97%.

How to calculate percentage in marks?

how to calculate percentage

To calculate the percentage of marks, divide the number of marks obtained by the total number of questions and multiply by 100.

For example, if you get 80 out of 100 on your exam: (80/100) x 100 = 80%.

Also, note that the above is not limited to exams; it can be applied for many other occasions.

For example, if you want to calculate the percentage of discount on a product: (discounted price/original price) x 100 = percentage of the discount.

How to calculate Percentage in Excel

To calculate percentage in Excel, use the formula =(B2/C2)*100. In this example, B2 is the cell with the number we need to find the percentage of and C2 is the total.

There are two ways to calculate a percentage:

  1. By using the = function

  2. Use a percent button on your calculator.

To use the = function, just type “=” then enter the number that you want to find the percentage of, divide it by 100, and press enter.

For example, to find what percentage 97 is of 100: =(97/100)*100.

To use a percent button on your calculator, first press the % button to enter percentage mode. Then, just enter the number you want to find the percentage of, divide it by 100, and press enter.

Percentage Difference Between Two Numbers

The percentage difference is the change in the value of a quantity over a period of time in terms of percentage. To calculate the percentage difference, subtract the old value from the new value and divide by the old value.

For example, if you have a quantity that is worth $100 and it increases to $105, the percentage difference would be (105-100)/100 = 5%.

How to Calculate Percentage Increase?

To calculate the percentage increase, subtract the old value from the new value and divide by the old value. Then, multiply by 100 to get the percentage.

For example, if you have a quantity that is worth $100 and it increases to $105, the percentage increase would be (105-100)/100 = 5%.

Similarly, if you have a quantity that is worth $100 and it decreases to $95, the percentage decrease would be (95-100)/100 = -5%.

How to Calculate Percentage Decrease?

To calculate the percentage decrease, subtract the old value from the new value and divide by the old value. Then, subtract 100 to get the percentage.

For example, if you have a quantity that is worth $100 and it decreases to $95, the percentage decrease would be (95-100)/100 = -5%.

Similarly, if you have a quantity that is worth $100 and it decreases to $75, the percentage decrease would be (75-100)/100 = -25%.

Percentage Difference Formula

Percentage formula

The percentage difference formula is: % difference = (new value – old value) / old value. In other words, to calculate the percentage difference, subtract the old value from the new value and divide by the old value.

For example, if you have a quantity that is worth $100 and it increases to $105, the percentage difference would be (105-100)/100 = 5%.

How to Calculate Multiple Percentage?

To calculate multiple percentages, you need to use an easier formula. Simply multiply the percentage by itself, then add 100 to it. This can be done on a calculator or on paper.

Reverse percentage formula

The reverse percentage formula is: % = (100 – (percentage * 100)). So, to calculate a percentage from a number, divide the number by 100 and subtract the result from 100.

For example, to calculate 25% from the number 97, use the formula 97 / 100 – 25. This will give you the answer 0.25.

How to Calculate Percentage Change?

To calculate percentage change, you need to use the percentage difference formula. However, in order to get the percentage change, you will need to subtract the old value from the new value and then divide that result by the old value.

For example, if you have a quantity that is worth $100 and it increases to $105, the percentage change would be (105-100)/100 = 5%.

Similarly, if you have a quantity that is worth $100 and it decreases to $95, the percentage change would be (95-100)/100 = -5%.
