How to work it out

  1. Gap between the values: |19 − 20| = 1
  2. Average of the values: (19 + 20) ÷ 2 = 19.5
  3. Divide the gap by the average and multiply by 100: 1 ÷ 19.5 × 100 = 5.1282%
  4. Check: Work backwards: 0.051282 × 19.5 = 1, the gap between the values.

In a spreadsheet: =ABS(19-20)/((19+20)/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

20 is 1 more than 19. Measured against their average, 19.5, that gap is 5.1282%. The result is the same whichever value you name first.

Prices: if one shop charges $19 and another $20 for the same item, the prices differ by 5.1282%.

Why the average is the base

Dividing the gap of 1 by 19 gives 5.2632%, and dividing it by 20 gives 5%. The average, 19.5, sits between them, so the result does not depend on which value is listed first.
