What is a percentage?

A percentage is a way of expressing a number as a fraction of 100. It commonly represents a proportion, ratio, or part of a while. It is denoted by the symbol “%” and has a diverse application in finance, statistics, accounting, retail, sales, and more.

How do you calculate the percentage?

The essence of calculating the percentage is the “percentage formula” itself. While there are several formulas for percentage problems, the most basic formula goes like this: 

Begin by dividing the number you want as a percentage of the total sum. Then, multiply this result by 100. The outcome indicates the percentage that the first number represents of the total.

$$Percentage\;=\;\left(\frac{Value}{Total\;Value}\right)\;\times\;100$$

Now, let’s examine an example. Suppose you have 80 apples and want to know what percentage of them are red, with 30 of those being red. You would divide 40 by 80 to get 0.5, then multiply by 100 to arrive at 50%. In simplest terms, half of the apples are red! 

How do you calculate the percentage difference? 

One of the most common percentage problems involves measuring the relative change (increase or decrease in percentage) between two values.

The percentage difference can be calculated by using the following formula: 

$$Percentage\;Difference\;=\;\left(\frac{\left|Value\;1-Value\;2\right|}{\displaystyle\frac{Value\;1+Value\;2}2}\right)\;\times\;100$$

Steps to Calculate:

1. Find the absolute difference between the two values.
2. Calculate the average of both values.
3. Divide the difference by the average, then multiply by 100 to get the percentage.

$$Example:\;If\;values\;are\;40\;and\;50:\;\left(\frac{\left|40-50\right|}{\displaystyle\frac{40+50}2}\right)\;\times\;100\;=\;22.22\%$$

How do you use the percentage increase/decrease calculator?
