How to work it out

  1. Gap between the values: |28 − 55| = 27
  2. Average of the values: (28 + 55) ÷ 2 = 41.5
  3. Divide the gap by the average and multiply by 100: 27 ÷ 41.5 × 100 = 65.0602%
  4. Check: Work backwards: 0.650602 × 41.5 = 27, the gap between the values.

In a spreadsheet: =ABS(28-55)/((28+55)/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

55 is 27 more than 28. Measured against their average, 41.5, that gap is 65.0602%. The result is the same whichever value you name first.

Prices: if one shop charges $28 and another $55 for the same item, the prices differ by 65.0602%.

Why the average is the base

Dividing the gap of 27 by 28 gives 96.4286%, and dividing it by 55 gives 49.0909%. The average, 41.5, sits between them, so the result does not depend on which value is listed first.
