How to work it out

  1. Gap between the values: |9 − 65| = 56
  2. Average of the values: (9 + 65) ÷ 2 = 37
  3. Divide the gap by the average and multiply by 100: 56 ÷ 37 × 100 = 151.3514%
  4. Check: Work backwards: 1.513514 × 37 = 56, the gap between the values.

In a spreadsheet: =ABS(9-65)/((9+65)/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

65 is 56 more than 9. Measured against their average, 37, that gap is 151.3514%. The result is the same whichever value you name first.

Prices: if one shop charges $9 and another $65 for the same item, the prices differ by 151.3514%.

Why the average is the base

Dividing the gap of 56 by 9 gives 622.2222%, and dividing it by 65 gives 86.1538%. The average, 37, sits between them, so the result does not depend on which value is listed first.
