About the Percentage Difference Calculator
Percentage difference compares two values symmetrically — neither is treated as the "original" — by measuring their gap relative to the average of the two. This differs from percentage change, which assumes one value is the starting point.
Formula: Percentage Difference = |A − B| ÷ ((A + B) ÷ 2) × 100
It's commonly used in science and statistics to compare two measurements of the same quantity, such as two experimental readings, without implying which one came first.
