How to work it out

  1. Gap between the values: |40 − 50| = 10
  2. Average of the values: (40 + 50) ÷ 2 = 45
  3. Divide the gap by the average and multiply by 100: 10 ÷ 45 × 100 = 22.2222%
  4. Check: Work backwards: 0.222222 × 45 = 10, the gap between the values.

In a spreadsheet: =ABS(40-50)/((40+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 10 more than 40. Measured against their average, 45, that gap is 22.2222%. The result is the same whichever value you name first.

Prices: if one shop charges $40 and another $50 for the same item, the prices differ by 22.2222%.

Why the average is the base

Dividing the gap of 10 by 40 gives 25%, and dividing it by 50 gives 20%. The average, 45, sits between them, so the result does not depend on which value is listed first.
