How to work it out

  1. Gap between the values: |11 − 12| = 1
  2. Average of the values: (11 + 12) ÷ 2 = 11.5
  3. Divide the gap by the average and multiply by 100: 1 ÷ 11.5 × 100 = 8.6957%
  4. Check: Work backwards: 0.086957 × 11.5 = 1, the gap between the values.

In a spreadsheet: =ABS(11-12)/((11+12)/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

12 is 1 more than 11. Measured against their average, 11.5, that gap is 8.6957%. The result is the same whichever value you name first.

Prices: if one shop charges $11 and another $12 for the same item, the prices differ by 8.6957%.

Why the average is the base

Dividing the gap of 1 by 11 gives 9.0909%, and dividing it by 12 gives 8.3333%. The average, 11.5, sits between them, so the result does not depend on which value is listed first.
