How to work it out

  1. Gap between the values: |51 − 55| = 4
  2. Average of the values: (51 + 55) ÷ 2 = 53
  3. Divide the gap by the average and multiply by 100: 4 ÷ 53 × 100 = 7.5472%
  4. Check: Work backwards: 0.075472 × 53 = 4, the gap between the values.

In a spreadsheet: =ABS(51-55)/((51+55)/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

55 is 4 more than 51. Measured against their average, 53, that gap is 7.5472%. The result is the same whichever value you name first.

Prices: if one shop charges $51 and another $55 for the same item, the prices differ by 7.5472%.

Why the average is the base

Dividing the gap of 4 by 51 gives 7.8431%, and dividing it by 55 gives 7.2727%. The average, 53, sits between them, so the result does not depend on which value is listed first.
