How to work it out

  1. Gap between the values: |56 − 66| = 10
  2. Average of the values: (56 + 66) ÷ 2 = 61
  3. Divide the gap by the average and multiply by 100: 10 ÷ 61 × 100 = 16.3934%
  4. Check: Work backwards: 0.163934 × 61 = 10, the gap between the values.

In a spreadsheet: =ABS(56-66)/((56+66)/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

66 is 10 more than 56. Measured against their average, 61, that gap is 16.3934%. The result is the same whichever value you name first.

Prices: if one shop charges $56 and another $66 for the same item, the prices differ by 16.3934%.

Why the average is the base

Dividing the gap of 10 by 56 gives 17.8571%, and dividing it by 66 gives 15.1515%. The average, 61, sits between them, so the result does not depend on which value is listed first.
