How to work it out

  1. Gap between the values: |18 − 43| = 25
  2. Average of the values: (18 + 43) ÷ 2 = 30.5
  3. Divide the gap by the average and multiply by 100: 25 ÷ 30.5 × 100 = 81.9672%
  4. Check: Work backwards: 0.819672 × 30.5 = 25, the gap between the values.

In a spreadsheet: =ABS(18-43)/((18+43)/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

43 is 25 more than 18. Measured against their average, 30.5, that gap is 81.9672%. The result is the same whichever value you name first.

Prices: if one shop charges $18 and another $43 for the same item, the prices differ by 81.9672%.

Why the average is the base

Dividing the gap of 25 by 18 gives 138.8889%, and dividing it by 43 gives 58.1395%. The average, 30.5, sits between them, so the result does not depend on which value is listed first.
