How to work it out

  1. Gap between the values: |27 − 57| = 30
  2. Average of the values: (27 + 57) ÷ 2 = 42
  3. Divide the gap by the average and multiply by 100: 30 ÷ 42 × 100 = 71.4286%
  4. Check: Work backwards: 0.714286 × 42 = 30, the gap between the values.

In a spreadsheet: =ABS(27-57)/((27+57)/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

57 is 30 more than 27. Measured against their average, 42, that gap is 71.4286%. The result is the same whichever value you name first.

Prices: if one shop charges $27 and another $57 for the same item, the prices differ by 71.4286%.

Why the average is the base

Dividing the gap of 30 by 27 gives 111.1111%, and dividing it by 57 gives 52.6316%. The average, 42, sits between them, so the result does not depend on which value is listed first.
