How to work it out

  1. Gap between the values: |61 − 90| = 29
  2. Average of the values: (61 + 90) ÷ 2 = 75.5
  3. Divide the gap by the average and multiply by 100: 29 ÷ 75.5 × 100 = 38.4106%
  4. Check: Work backwards: 0.384106 × 75.5 = 29, the gap between the values.

In a spreadsheet: =ABS(61-90)/((61+90)/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

90 is 29 more than 61. Measured against their average, 75.5, that gap is 38.4106%. The result is the same whichever value you name first.

Prices: if one shop charges $61 and another $90 for the same item, the prices differ by 38.4106%.

Why the average is the base

Dividing the gap of 29 by 61 gives 47.541%, and dividing it by 90 gives 32.2222%. The average, 75.5, sits between them, so the result does not depend on which value is listed first.
