Calculating Percentages

Simply click on the calculate button to get the results of percentage calculations. You will see the result on the next page. If there are errors in the input fields, the result page will be blank. The program allows you to calculate the difference between two numbers in percentages. You can also input a percentage of any number and get the numeric value. Although it is a simple calculator, it can be very useful in many scenarios. Our goal is to give you an easy to use percentage calculator that gives you results you want fast.

Percentage in mathematics refers to fractions based in 100. It is usually represented by “%,” “pct,” or “percentage.” This web app allows a comma or dot as a decimal separator. So you can use both freely.

We have provided several examples for you to use. You can use the examples to feed in your own data correctly. We hope you will find this site useful for calculang percentages. You can even use it for crosschecking the accuracy of your assignment results.

NB. Americans use “percent,” which the British prefer “per cent.”


Example one

Calculate 20% of 200?
20% of 200 =____
(200/100) x 20 = _____
2 x 20 = 40

It is quite easy. Just divide 200 by 100 to get one percent. The result is 2. Then multiply it by 20 ( 20% = 20 per hundred) = 20 x 2 = 40

Example two

What percentage of 125 is 50?

50 = ---% of 125
50 x (100/125) = 40%

Get the value of one percent by dividing 100 by 125. After that, multiply the value by 50 to get the percentage value of 50 units, which is 40% That is how to calculate the percentage.

Example three

What is the percentage (%) change (increase or decrease) from 120 to 150?

(150-120) x (100/120) = 36

Since 150 represents 100%. One percent will be equal to 100/150. 150-120 is 30. Therefore, 30 units represents 30 x (100/150) = 36 % This is how to calculate the percentage increase.

we do not use a percentage at all times. There are scenarios where we simply want to show the ratio of numbers. For instance, what is 20% of 50? This can also be interpreted as 20 hundredths of 50. This equates to 20/100 x 50 = 10.

You can use a calculation trick here. Anyme you want to divide a number by 100, just move the decimal two places to the left. 20/100 x 50 calculated above can also be writen as (20 x 50)/100. Since 20x 50 =1000. You can simply divide 1000 by 100 by moving two decimal places to the left, which gives you 10.

In another scenario, you want to calculate the percentage increase or decrease. Supposing you have $10 and spend $2 to buy candy, then you have spent 20% of your money. So how much will be remaining? All the money you have is 100%, if you spend 20%, you will have 80% remaining. You can simply use the percentage reduction tool above to calculate this value.


The word percent is derived from the Latin word percenter which means per hundred, and it is designated by %
