How to work it out

  1. Gap between the values: |6 − 9| = 3
  2. Average of the values: (6 + 9) ÷ 2 = 7.5
  3. Divide the gap by the average and multiply by 100: 3 ÷ 7.5 × 100 = 40%
  4. Check: Work backwards: 0.4 × 7.5 = 3, the gap between the values.

In a spreadsheet: =ABS(6-9)/((6+9)/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

9 is 3 more than 6. Measured against their average, 7.5, that gap is 40%. The result is the same whichever value you name first.

Prices: if one shop charges $6 and another $9 for the same item, the prices differ by 40%.

Why the average is the base

Dividing the gap of 3 by 6 gives 50%, and dividing it by 9 gives 33.3333%. The average, 7.5, sits between them, so the result does not depend on which value is listed first.
