Formula and methodology
Formula: Percentage difference = |first − second| / ((|first| + |second|)/2) × 100.
Unlike percentage change, percentage difference treats both values symmetrically and uses their average magnitude as the reference.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- First value — minimum -1000000000; maximum 1000000000
- Second value — minimum -1000000000; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| First value | 90 |
| Second value | 100 |
Absolute difference = 10; percentage difference ≈ 10.526%.
Assumptions and limits
- The average of the two magnitudes is not zero.
- The inputs are comparable measurements with the same unit.
- No measurement uncertainty or significance test is inferred.
