How to Calculate Percentage Difference
Formula
Percentage difference measures how far apart two values are relative to their average. Unlike percentage change, it treats both values symmetrically.
The formula divides the absolute difference by the mean of the two values, then multiplies by 100.
Common use cases:
- Comparing experimental measurements
- Evaluating competing price quotes
- Scientific data analysis
