How to work it out

  1. Gap between the values: |64 − 100| = 36
  2. Average of the values: (64 + 100) ÷ 2 = 82
  3. Divide the gap by the average and multiply by 100: 36 ÷ 82 × 100 = 43.9024%
  4. Check: Work backwards: 0.439024 × 82 = 36, the gap between the values.

In a spreadsheet: =ABS(64-100)/((64+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 36 more than 64. Measured against their average, 82, that gap is 43.9024%. The result is the same whichever value you name first.

Prices: if one shop charges $64 and another $100 for the same item, the prices differ by 43.9024%.

Why the average is the base

Dividing the gap of 36 by 64 gives 56.25%, and dividing it by 100 gives 36%. The average, 82, sits between them, so the result does not depend on which value is listed first.
