How to work it out

  1. Gap between the values: |31 − 56| = 25
  2. Average of the values: (31 + 56) ÷ 2 = 43.5
  3. Divide the gap by the average and multiply by 100: 25 ÷ 43.5 × 100 = 57.4713%
  4. Check: Work backwards: 0.574713 × 43.5 = 25, the gap between the values.

In a spreadsheet: =ABS(31-56)/((31+56)/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

56 is 25 more than 31. Measured against their average, 43.5, that gap is 57.4713%. The result is the same whichever value you name first.

Prices: if one shop charges $31 and another $56 for the same item, the prices differ by 57.4713%.

Why the average is the base

Dividing the gap of 25 by 31 gives 80.6452%, and dividing it by 56 gives 44.6429%. The average, 43.5, sits between them, so the result does not depend on which value is listed first.
