How to work it out

  1. Gap between the values: |61 − 78| = 17
  2. Average of the values: (61 + 78) ÷ 2 = 69.5
  3. Divide the gap by the average and multiply by 100: 17 ÷ 69.5 × 100 = 24.4604%
  4. Check: Work backwards: 0.244604 × 69.5 = 17, the gap between the values.

In a spreadsheet: =ABS(61-78)/((61+78)/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

78 is 17 more than 61. Measured against their average, 69.5, that gap is 24.4604%. The result is the same whichever value you name first.

Prices: if one shop charges $61 and another $78 for the same item, the prices differ by 24.4604%.

Why the average is the base

Dividing the gap of 17 by 61 gives 27.8689%, and dividing it by 78 gives 21.7949%. The average, 69.5, sits between them, so the result does not depend on which value is listed first.
