Percentage Difference Calculator
Compare two peer values with symmetric percentage difference, absolute difference, average baseline, and larger-to-smaller ratio.
What percentage difference means
Percentage difference compares two peer values without assuming that either value is the starting point. The result is symmetric, so swapping the values does not change the answer.
P_diff is the percentage difference, A and B are peer values, and x_bar is the average baseline.
Percent difference vs percent change
| Metric | Use when |
|---|---|
| Percentage difference | Two values are peers and order does not matter |
| Percentage change | There is an old value and a new value |
| Percent error | One value is measured and the other is accepted or expected |
