How to work it out

  1. Gap between the values: |68 − 90| = 22
  2. Average of the values: (68 + 90) ÷ 2 = 79
  3. Divide the gap by the average and multiply by 100: 22 ÷ 79 × 100 = 27.8481%
  4. Check: Work backwards: 0.278481 × 79 = 22, the gap between the values.

In a spreadsheet: =ABS(68-90)/((68+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 22 more than 68. Measured against their average, 79, that gap is 27.8481%. The result is the same whichever value you name first.

Prices: if one shop charges $68 and another $90 for the same item, the prices differ by 27.8481%.

Why the average is the base

Dividing the gap of 22 by 68 gives 32.3529%, and dividing it by 90 gives 24.4444%. The average, 79, sits between them, so the result does not depend on which value is listed first.
