How to work it out

  1. Gap between the values: |20 − 50| = 30
  2. Average of the values: (20 + 50) ÷ 2 = 35
  3. Divide the gap by the average and multiply by 100: 30 ÷ 35 × 100 = 85.7143%
  4. Check: Work backwards: 0.857143 × 35 = 30, the gap between the values.

In a spreadsheet: =ABS(20-50)/((20+50)/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

50 is 30 more than 20. Measured against their average, 35, that gap is 85.7143%. The result is the same whichever value you name first.

Prices: if one shop charges $20 and another $50 for the same item, the prices differ by 85.7143%.

Why the average is the base

Dividing the gap of 30 by 20 gives 150%, and dividing it by 50 gives 60%. The average, 35, sits between them, so the result does not depend on which value is listed first.
