How to work it out

  1. Gap between the values: |42 − 65| = 23
  2. Average of the values: (42 + 65) ÷ 2 = 53.5
  3. Divide the gap by the average and multiply by 100: 23 ÷ 53.5 × 100 = 42.9907%
  4. Check: Work backwards: 0.429907 × 53.5 = 23, the gap between the values.

In a spreadsheet: =ABS(42-65)/((42+65)/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

65 is 23 more than 42. Measured against their average, 53.5, that gap is 42.9907%. The result is the same whichever value you name first.

Prices: if one shop charges $42 and another $65 for the same item, the prices differ by 42.9907%.

Why the average is the base

Dividing the gap of 23 by 42 gives 54.7619%, and dividing it by 65 gives 35.3846%. The average, 53.5, sits between them, so the result does not depend on which value is listed first.
