How to work it out

  1. Gap between the values: |72 − 100| = 28
  2. Average of the values: (72 + 100) ÷ 2 = 86
  3. Divide the gap by the average and multiply by 100: 28 ÷ 86 × 100 = 32.5581%
  4. Check: Work backwards: 0.325581 × 86 = 28, the gap between the values.

In a spreadsheet: =ABS(72-100)/((72+100)/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

100 is 28 more than 72. Measured against their average, 86, that gap is 32.5581%. The result is the same whichever value you name first.

Prices: if one shop charges $72 and another $100 for the same item, the prices differ by 32.5581%.

Why the average is the base

Dividing the gap of 28 by 72 gives 38.8889%, and dividing it by 100 gives 28%. The average, 86, sits between them, so the result does not depend on which value is listed first.
