Find the percentage difference between any two values
Percentage difference and percentage change are different calculations. Percentage difference compares two values without treating either as the "original" — it divides the absolute difference by the average of the two values. Percentage change specifically measures how much a value increased or decreased from an original baseline.
Percentage Difference = (|Value1 - Value2| ÷ ((Value1 + Value2) ÷ 2)) × 100. This gives a symmetric result — the percentage difference between 75 and 100 is the same as between 100 and 75.
