How to work it out

  1. Gap between the values: |12 − 54| = 42
  2. Average of the values: (12 + 54) ÷ 2 = 33
  3. Divide the gap by the average and multiply by 100: 42 ÷ 33 × 100 = 127.2727%
  4. Check: Work backwards: 1.272727 × 33 = 42, the gap between the values.

In a spreadsheet: =ABS(12-54)/((12+54)/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

54 is 42 more than 12. Measured against their average, 33, that gap is 127.2727%. The result is the same whichever value you name first.

Prices: if one shop charges $12 and another $54 for the same item, the prices differ by 127.2727%.

Why the average is the base

Dividing the gap of 42 by 12 gives 350%, and dividing it by 54 gives 77.7778%. The average, 33, sits between them, so the result does not depend on which value is listed first.
