What is Percentage Difference?
Percentage difference compares two values by finding the absolute difference between them, divided by their average, then multiplied by 100. Unlike percentage change, it doesn't matter which value is "original" - the result is always the same.
Understanding Percentage Difference
Percentage difference compares two values using their average as the reference point, making it useful when neither value is the "original."
Formula: |V1 - V2| ÷ ((|V1| + |V2|) / 2) × 100
Example
Comparing 80 and 100: |80 - 100| ÷ ((80 + 100) / 2) × 100 = 20 ÷ 90 × 100 = 22.22% difference.
