How to work it out

  1. Gap between the values: |55 − 82| = 27
  2. Average of the values: (55 + 82) ÷ 2 = 68.5
  3. Divide the gap by the average and multiply by 100: 27 ÷ 68.5 × 100 = 39.4161%
  4. Check: Work backwards: 0.394161 × 68.5 = 27, the gap between the values.

In a spreadsheet: =ABS(55-82)/((55+82)/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

82 is 27 more than 55. Measured against their average, 68.5, that gap is 39.4161%. The result is the same whichever value you name first.

Prices: if one shop charges $55 and another $82 for the same item, the prices differ by 39.4161%.

Why the average is the base

Dividing the gap of 27 by 55 gives 49.0909%, and dividing it by 82 gives 32.9268%. The average, 68.5, sits between them, so the result does not depend on which value is listed first.
