How to work it out

  1. Gap between the values: |15 − 86| = 71
  2. Average of the values: (15 + 86) ÷ 2 = 50.5
  3. Divide the gap by the average and multiply by 100: 71 ÷ 50.5 × 100 = 140.5941%
  4. Check: Work backwards: 1.405941 × 50.5 = 71, the gap between the values.

In a spreadsheet: =ABS(15-86)/((15+86)/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

86 is 71 more than 15. Measured against their average, 50.5, that gap is 140.5941%. The result is the same whichever value you name first.

Prices: if one shop charges $15 and another $86 for the same item, the prices differ by 140.5941%.

Why the average is the base

Dividing the gap of 71 by 15 gives 473.3333%, and dividing it by 86 gives 82.5581%. The average, 50.5, sits between them, so the result does not depend on which value is listed first.
