## What is Percentage Difference?

Percentage difference is a measure used to express the relative difference between two values as a percentage of their average or one of the values. It is commonly used to compare two values and determine how much they differ from each other in relative terms.

## All Formulae Related to Percentage Difference

Percentage difference is a measure used to calculate the relative difference between two values as a percentage of their average or one of the values. The formula for calculating percentage difference is as follows:

**Percentage Difference = [(|Value 1 – Value 2|) / ((Value 1 + Value 2) / 2)] x 100%**

Where:

**Percentage Difference:**The percentage by which the two values differ.**Value 1:**The first value.**Value 2:**The second value.- The absolute value (denoted by | |) is used to ensure that the result is always positive.
