How to work it out

  1. Gap between the values: |26 − 31| = 5
  2. Average of the values: (26 + 31) ÷ 2 = 28.5
  3. Divide the gap by the average and multiply by 100: 5 ÷ 28.5 × 100 = 17.5439%
  4. Check: Work backwards: 0.175439 × 28.5 = 5, the gap between the values.

In a spreadsheet: =ABS(26-31)/((26+31)/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

31 is 5 more than 26. Measured against their average, 28.5, that gap is 17.5439%. The result is the same whichever value you name first.

Prices: if one shop charges $26 and another $31 for the same item, the prices differ by 17.5439%.

Why the average is the base

Dividing the gap of 5 by 26 gives 19.2308%, and dividing it by 31 gives 16.129%. The average, 28.5, sits between them, so the result does not depend on which value is listed first.
