$$ Percentage\; Difference \;=\; \biggr| \frac{initial \; value - final \; value}{\frac{initial \; value + final \; value}{2}} \biggr| * 100 $$

Vf= final value from the given data

Vi= Initial value from the data sample

vi+vf/2= represent the middle value

## Working Behind Difference Percentage Calculator

The percentage calculator difference uses a simple procedure to evaluate the change in percentage values so that you can understand them effortlessly. When you give the input value of two numbers in the calculator to find the percent difference, It checks all the given values.

After checking the percentage of difference calculator starts calculating the given data with the help of the percent difference formula. First, it **subtracts the initial value** from the final value and adds initial and final values. After addition divide by 2 to get the middles number between these values. Then the result of subtraction is divided by the middle value.

Last, the division result is multiplied by 100, and in a few seconds, you get the solution of the relative percentage difference. Now let's see an example of a percent difference to understand its evaluation process of the percent difference calculator.

## Solved Example of Percentage Difference

The percentage difference calculator can be used to solve the percentage difference but it can also be found manually. We are going to give you an example to let you know how to find it manually.

### Example:

Determine the percent difference between the numbers 30 and 15.

**Solution:**

Let a = 30 and b = 15

$$ a\; - b \;=\; 30 -15 \;=\; 15 $$

$$ \biggr| a\; - \;b \biggr| \;=\; |15| \;=\; 15 $$

$$ \frac{(a+b)}{2} $$

$$ \frac{30+15}{2} $$

$$ \frac{45}{2} \;=\; 22.5 $$

$$ Percent\; difference \;=\; \biggr[\frac{|a-b|}{\frac{(a+b)}{2}} \biggr] * 100 $$

$$ Percent\; Difference \;=\; \frac{|15|}{22.5} * 100 $$

$$ Percent\; Difference \;=\; 0.666 * 100 \;=\; 66.7% $$
