How to work it out

  1. Gap between the values: |54 − 73| = 19
  2. Average of the values: (54 + 73) ÷ 2 = 63.5
  3. Divide the gap by the average and multiply by 100: 19 ÷ 63.5 × 100 = 29.9213%
  4. Check: Work backwards: 0.299213 × 63.5 = 19, the gap between the values.

In a spreadsheet: =ABS(54-73)/((54+73)/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

73 is 19 more than 54. Measured against their average, 63.5, that gap is 29.9213%. The result is the same whichever value you name first.

Prices: if one shop charges $54 and another $73 for the same item, the prices differ by 29.9213%.

Why the average is the base

Dividing the gap of 19 by 54 gives 35.1852%, and dividing it by 73 gives 26.0274%. The average, 63.5, sits between them, so the result does not depend on which value is listed first.
