How to work it out

  1. Gap between the values: |31 − 61| = 30
  2. Average of the values: (31 + 61) ÷ 2 = 46
  3. Divide the gap by the average and multiply by 100: 30 ÷ 46 × 100 = 65.2174%
  4. Check: Work backwards: 0.652174 × 46 = 30, the gap between the values.

In a spreadsheet: =ABS(31-61)/((31+61)/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

61 is 30 more than 31. Measured against their average, 46, that gap is 65.2174%. The result is the same whichever value you name first.

Prices: if one shop charges $31 and another $61 for the same item, the prices differ by 65.2174%.

Why the average is the base

Dividing the gap of 30 by 31 gives 96.7742%, and dividing it by 61 gives 49.1803%. The average, 46, sits between them, so the result does not depend on which value is listed first.
