## What is the percentage difference?

The percentage difference between two values is a mathematical method to compare differences between two values. The percentage difference is based on the division of the absolute difference and the average.

Percentage difference expresses results in percents, and therefore the results represent fractions of 100.

The order of the two values that are calculated doesn't matter in percentage difference.

## How to calculate percentage difference step by step?

To find the percentage difference between two values, you first need to calculate the absolute difference and the average between the values.

Here is a step by step formula how to calculate percentage difference:

1. Calculate the absolute difference of the numbers

The first step in the formula is to calculate the absolute difference between two values. This is achieved with simple subtraction.

2. Calculate the average of the numbers

The second step is to calculate the average of the numbers by adding the two numbers together and dividing them by 2.

3. Divide the absolute difference by the average

After you have found the absolute difference and the average, divide the former by the latter.

4. Convert your result into a percentage

The last step is to convert your result to a percentage, by multiplying the result by 100.

## What is the percentage difference formula?

Percentage difference = (Absolute difference / Average) x 100

For two values X and Y, the percentage difference is as following:

Absolute difference = |x - y|

Average = (x - y) / 2

Percentage difference = (|x - y|) / ((x - y) / 2)) * 100

## When I should use the percentage difference?

When you are comparing two values, you should consider how you are comparing those values. If the compared values have an old value and a new value, then the percentage change should be calculated. And if the values are not time-related, and they measure the differences, then percentage difference is more suitable for the occasion.

## What is the difference between percentage difference and percentage change?

The key difference between the two is that the percentage change measures change over time, and the percentage difference compares the difference between the two values.

The percentage difference and the percentage change are often used to compare two values.

Percent change shows the difference between the old and the new values of a quantity.

The percentage difference is the absolute difference divided with the average of the numbers and therefore compares the values directly.

## What is the percentage?

A percentage is a number that can be represented as a fraction of a whole, which is divided into 100 fractions. So 1 percent represents 1/100 of a whole.
