Percentage Calculator: Frequently Asked Questions (FAQ)
Before proceeding to how to calculate percentages, first make sure we are all on the same page, so let’s start with the most important question: What are percentages?
The term "percent" means 1 out of 100 OR ‘percent’ means for every 100.
In mathematics, percentages are used to describe parts of a whole, which is being distributed in hundred equal parts.
The percentage symbol (%) is used to show that the number is a percentage.
So, as described above, we take total value equals to 100%. For example, if you have 20 oranges (= 100%). If you ate five oranges, then in percentage, you have eaten 5/20 × 100% = 25% of your oranges and left with 75% oranges.
There are lots of reasons why you should know how to calculate percentages, as knowing how to find the percentage of a number will not only help you score well in your mathematics tests but will also assist you in the real world.
For instance, you want to buy a new smartphone for £400 -- you have checked all online stores and found that one website is offering 20% discount on the retail value of the smartphone.
So, how much will that smartphone cost you taking into account the discount offered?
If you don’t know basics of mathematics formulas, don’t worry, because how to calculate percentages can be much easier than you may realize.
20% of 400 is — (20/400) * 100 = £80 Discount amount.
So, that smartphone you searched online at 20% discount will cost you £(400-80) = £320.
But, if you are not sure how to perform any of those handy calculations or are in a hurry, you are highly recommended to use our online percentage calculator given above to speed up your calculations.
The formula for calculating percentages or for converting anything from percentages is fairly straightforward.
There are many formulae for percentage problems, and to calculate the percent of a total, you can use a below-mentioned formula that simply divides an amount by the total.
Percentage = (Value/Total Value) * 100
Here's an example of how to quickly calculate percentage using the formula for percentage:
What is 12% of 70? This can be solved in two steps:
Step 1: Write 12% as a decimal number: 12% = 0.12
Step 2: Multiply 0.12 and 70 to get the answer: 0.12 * 70 = 8.40
When calculating a percent in Excel, you will be happy to know that it has tools to make your life easier.
In Excel, you do not have to multiply resulting fraction by 100, because it does this automatically when the percentage format is applied to a cell.
Basic Excel percentage formula — Part/Total = Percentage
To calculate the percentage of a number in Excel, simply multiply the percentage value by the number that you want the percentage of.
For example, if you want to calculate 17% of 50, multiply 17% by 50.
Mean, just type the following formula into an Excel cell as = 17%*50 which gives the result 8.5.
The percent difference is a mathematical way of comparing percentage difference between two given numbers.
The percent difference between two numbers is the difference between the two numbers divided by their average.
For example, if you want to calculate the percent difference between two numbers 80 and 50; then the calculation as follows:
Difference is 80 − 50 = 30
Average is (80 + 50) / 2 = 65
Percentage Difference = (30/65) * 100 = 0.4615 * 100 = 46.15%
