How to work it out

  1. Gap between the values: |42 − 55| = 13
  2. Average of the values: (42 + 55) ÷ 2 = 48.5
  3. Divide the gap by the average and multiply by 100: 13 ÷ 48.5 × 100 = 26.8041%
  4. Check: Work backwards: 0.268041 × 48.5 = 13, the gap between the values.

In a spreadsheet: =ABS(42-55)/((42+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 13 more than 42. Measured against their average, 48.5, that gap is 26.8041%. The result is the same whichever value you name first.

Prices: if one shop charges $42 and another $55 for the same item, the prices differ by 26.8041%.

Why the average is the base

Dividing the gap of 13 by 42 gives 30.9524%, and dividing it by 55 gives 23.6364%. The average, 48.5, sits between them, so the result does not depend on which value is listed first.
