How to work it out

  1. Gap between the values: |25 − 50| = 25
  2. Average of the values: (25 + 50) ÷ 2 = 37.5
  3. Divide the gap by the average and multiply by 100: 25 ÷ 37.5 × 100 = 66.6667%
  4. Check: Work backwards: 0.666667 × 37.5 = 25, the gap between the values.

In a spreadsheet: =ABS(25-50)/((25+50)/2)*100. Dividing by one of the values instead of their average turns it into a percentage change, which depends on which value you start from.

What the result means

50 is 25 more than 25. Measured against their average, 37.5, that gap is 66.6667%. The result is the same whichever value you name first.

Prices: if one shop charges $25 and another $50 for the same item, the prices differ by 66.6667%.

Why the average is the base

Dividing the gap of 25 by 25 gives 100%, and dividing it by 50 gives 50%. The average, 37.5, sits between them, so the result does not depend on which value is listed first.
