How to work it out

  1. Gap between the values: |42 − 66| = 24
  2. Average of the values: (42 + 66) ÷ 2 = 54
  3. Divide the gap by the average and multiply by 100: 24 ÷ 54 × 100 = 44.4444%
  4. Check: Work backwards: 0.444444 × 54 = 24, the gap between the values.

In a spreadsheet: =ABS(42-66)/((42+66)/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

66 is 24 more than 42. Measured against their average, 54, that gap is 44.4444%. The result is the same whichever value you name first.

Prices: if one shop charges $42 and another $66 for the same item, the prices differ by 44.4444%.

Why the average is the base

Dividing the gap of 24 by 42 gives 57.1429%, and dividing it by 66 gives 36.3636%. The average, 54, sits between them, so the result does not depend on which value is listed first.
