How to work it out

  1. Gap between the values: |27 − 34| = 7
  2. Average of the values: (27 + 34) ÷ 2 = 30.5
  3. Divide the gap by the average and multiply by 100: 7 ÷ 30.5 × 100 = 22.9508%
  4. Check: Work backwards: 0.229508 × 30.5 = 7, the gap between the values.

In a spreadsheet: =ABS(27-34)/((27+34)/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

34 is 7 more than 27. Measured against their average, 30.5, that gap is 22.9508%. The result is the same whichever value you name first.

Prices: if one shop charges $27 and another $34 for the same item, the prices differ by 22.9508%.

Why the average is the base

Dividing the gap of 7 by 27 gives 25.9259%, and dividing it by 34 gives 20.5882%. The average, 30.5, sits between them, so the result does not depend on which value is listed first.
