How to work it out

  1. Gap between the values: |12 − 90| = 78
  2. Average of the values: (12 + 90) ÷ 2 = 51
  3. Divide the gap by the average and multiply by 100: 78 ÷ 51 × 100 = 152.9412%
  4. Check: Work backwards: 1.529412 × 51 = 78, the gap between the values.

In a spreadsheet: =ABS(12-90)/((12+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 78 more than 12. Measured against their average, 51, that gap is 152.9412%. The result is the same whichever value you name first.

Prices: if one shop charges $12 and another $90 for the same item, the prices differ by 152.9412%.

Why the average is the base

Dividing the gap of 78 by 12 gives 650%, and dividing it by 90 gives 86.6667%. The average, 51, sits between them, so the result does not depend on which value is listed first.
