How to work it out

  1. Gap between the values: |28 − 90| = 62
  2. Average of the values: (28 + 90) ÷ 2 = 59
  3. Divide the gap by the average and multiply by 100: 62 ÷ 59 × 100 = 105.0847%
  4. Check: Work backwards: 1.050847 × 59 = 62, the gap between the values.

In a spreadsheet: =ABS(28-90)/((28+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 62 more than 28. Measured against their average, 59, that gap is 105.0847%. The result is the same whichever value you name first.

Prices: if one shop charges $28 and another $90 for the same item, the prices differ by 105.0847%.

Why the average is the base

Dividing the gap of 62 by 28 gives 221.4286%, and dividing it by 90 gives 68.8889%. The average, 59, sits between them, so the result does not depend on which value is listed first.
