How to work it out

  1. Gap between the values: |47 − 81| = 34
  2. Average of the values: (47 + 81) ÷ 2 = 64
  3. Divide the gap by the average and multiply by 100: 34 ÷ 64 × 100 = 53.125%
  4. Check: Work backwards: 0.53125 × 64 = 34, the gap between the values.

In a spreadsheet: =ABS(47-81)/((47+81)/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

81 is 34 more than 47. Measured against their average, 64, that gap is 53.125%. The result is the same whichever value you name first.

Prices: if one shop charges $47 and another $81 for the same item, the prices differ by 53.125%.

Why the average is the base

Dividing the gap of 34 by 47 gives 72.3404%, and dividing it by 81 gives 41.9753%. The average, 64, sits between them, so the result does not depend on which value is listed first.
