How to work it out

  1. Gap between the values: |20 − 57| = 37
  2. Average of the values: (20 + 57) ÷ 2 = 38.5
  3. Divide the gap by the average and multiply by 100: 37 ÷ 38.5 × 100 = 96.1039%
  4. Check: Work backwards: 0.961039 × 38.5 = 37, the gap between the values.

In a spreadsheet: =ABS(20-57)/((20+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 37 more than 20. Measured against their average, 38.5, that gap is 96.1039%. The result is the same whichever value you name first.

Prices: if one shop charges $20 and another $57 for the same item, the prices differ by 96.1039%.

Why the average is the base

Dividing the gap of 37 by 20 gives 185%, and dividing it by 57 gives 64.9123%. The average, 38.5, sits between them, so the result does not depend on which value is listed first.
