How to work it out

  1. Gap between the values: |20 − 34| = 14
  2. Average of the values: (20 + 34) ÷ 2 = 27
  3. Divide the gap by the average and multiply by 100: 14 ÷ 27 × 100 = 51.8519%
  4. Check: Work backwards: 0.518519 × 27 = 14, the gap between the values.

In a spreadsheet: =ABS(20-34)/((20+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 14 more than 20. Measured against their average, 27, that gap is 51.8519%. The result is the same whichever value you name first.

Prices: if one shop charges $20 and another $34 for the same item, the prices differ by 51.8519%.

Why the average is the base

Dividing the gap of 14 by 20 gives 70%, and dividing it by 34 gives 41.1765%. The average, 27, sits between them, so the result does not depend on which value is listed first.
