How to work it out

  1. Gap between the values: |54 − 66| = 12
  2. Average of the values: (54 + 66) ÷ 2 = 60
  3. Divide the gap by the average and multiply by 100: 12 ÷ 60 × 100 = 20%
  4. Check: Work backwards: 0.2 × 60 = 12, the gap between the values.

In a spreadsheet: =ABS(54-66)/((54+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 12 more than 54. Measured against their average, 60, that gap is 20%. The result is the same whichever value you name first.

Prices: if one shop charges $54 and another $66 for the same item, the prices differ by 20%.

Why the average is the base

Dividing the gap of 12 by 54 gives 22.2222%, and dividing it by 66 gives 18.1818%. The average, 60, sits between them, so the result does not depend on which value is listed first.
