How to work it out

  1. Gap between the values: |33 − 66| = 33
  2. Average of the values: (33 + 66) ÷ 2 = 49.5
  3. Divide the gap by the average and multiply by 100: 33 ÷ 49.5 × 100 = 66.6667%
  4. Check: Work backwards: 0.666667 × 49.5 = 33, the gap between the values.

In a spreadsheet: =ABS(33-66)/((33+66)/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

66 is 33 more than 33. Measured against their average, 49.5, that gap is 66.6667%. The result is the same whichever value you name first.

Prices: if one shop charges $33 and another $66 for the same item, the prices differ by 66.6667%.

Why the average is the base

Dividing the gap of 33 by 33 gives 100%, and dividing it by 66 gives 50%. The average, 49.5, sits between them, so the result does not depend on which value is listed first.
