How to work it out

  1. Gap between the values: |6 − 15| = 9
  2. Average of the values: (6 + 15) ÷ 2 = 10.5
  3. Divide the gap by the average and multiply by 100: 9 ÷ 10.5 × 100 = 85.7143%
  4. Check: Work backwards: 0.857143 × 10.5 = 9, the gap between the values.

In a spreadsheet: =ABS(6-15)/((6+15)/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

15 is 9 more than 6. Measured against their average, 10.5, that gap is 85.7143%. The result is the same whichever value you name first.

Prices: if one shop charges $6 and another $15 for the same item, the prices differ by 85.7143%.

Why the average is the base

Dividing the gap of 9 by 6 gives 150%, and dividing it by 15 gives 60%. The average, 10.5, sits between them, so the result does not depend on which value is listed first.
