How to work it out

  1. Gap between the values: |56 − 57| = 1
  2. Average of the values: (56 + 57) ÷ 2 = 56.5
  3. Divide the gap by the average and multiply by 100: 1 ÷ 56.5 × 100 = 1.7699%
  4. Check: Work backwards: 0.017699 × 56.5 = 1, the gap between the values.

In a spreadsheet: =ABS(56-57)/((56+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 1 more than 56. Measured against their average, 56.5, that gap is 1.7699%. The result is the same whichever value you name first.

Prices: if one shop charges $56 and another $57 for the same item, the prices differ by 1.7699%.

Why the average is the base

Dividing the gap of 1 by 56 gives 1.7857%, and dividing it by 57 gives 1.7544%. The average, 56.5, sits between them, so the result does not depend on which value is listed first.
