Percentage Difference Calculator
Calculate the percentage difference between two values. The percentage difference is calculated as the absolute difference between two values divided by the average of those values.
Formula & Explanation
The percentage difference between two values is calculated using this formula:
% Difference = |V₁ - V₂| / [(V₁ + V₂) / 2] × 100
- |V₁ - V₂| = Absolute difference between values
- (V₁ + V₂) / 2 = Average of the two values
- × 100 = Convert to percentage
Percentage Difference
Example
If Value 1 = 80 and Value 2 = 60:
Difference = |80 - 60| = 20
Average = (80 + 60) / 2 = 70
Percentage Difference = (20 / 70) × 100 = 28.57%
