How to work it out

  1. Gap between the values: |1 − 28| = 27
  2. Average of the values: (1 + 28) ÷ 2 = 14.5
  3. Divide the gap by the average and multiply by 100: 27 ÷ 14.5 × 100 = 186.2069%
  4. Check: Work backwards: 1.862069 × 14.5 = 27, the gap between the values.

In a spreadsheet: =ABS(1-28)/((1+28)/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

28 is 27 more than 1. Measured against their average, 14.5, that gap is 186.2069%. The result is the same whichever value you name first.

Prices: if one shop charges $1 and another $28 for the same item, the prices differ by 186.2069%.

Why the average is the base

Dividing the gap of 27 by 1 gives 2,700%, and dividing it by 28 gives 96.4286%. The average, 14.5, sits between them, so the result does not depend on which value is listed first.
