How to work it out

  1. Gap between the values: |51 − 57| = 6
  2. Average of the values: (51 + 57) ÷ 2 = 54
  3. Divide the gap by the average and multiply by 100: 6 ÷ 54 × 100 = 11.1111%
  4. Check: Work backwards: 0.111111 × 54 = 6, the gap between the values.

In a spreadsheet: =ABS(51-57)/((51+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 6 more than 51. Measured against their average, 54, that gap is 11.1111%. The result is the same whichever value you name first.

Prices: if one shop charges $51 and another $57 for the same item, the prices differ by 11.1111%.

Why the average is the base

Dividing the gap of 6 by 51 gives 11.7647%, and dividing it by 57 gives 10.5263%. The average, 54, sits between them, so the result does not depend on which value is listed first.
