How to work it out

  1. Gap between the values: |83 − 100| = 17
  2. Average of the values: (83 + 100) ÷ 2 = 91.5
  3. Divide the gap by the average and multiply by 100: 17 ÷ 91.5 × 100 = 18.5792%
  4. Check: Work backwards: 0.185792 × 91.5 = 17, the gap between the values.

In a spreadsheet: =ABS(83-100)/((83+100)/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

100 is 17 more than 83. Measured against their average, 91.5, that gap is 18.5792%. The result is the same whichever value you name first.

Prices: if one shop charges $83 and another $100 for the same item, the prices differ by 18.5792%.

Why the average is the base

Dividing the gap of 17 by 83 gives 20.4819%, and dividing it by 100 gives 17%. The average, 91.5, sits between them, so the result does not depend on which value is listed first.
