How to work it out

  1. Gap between the values: |42 − 79| = 37
  2. Average of the values: (42 + 79) ÷ 2 = 60.5
  3. Divide the gap by the average and multiply by 100: 37 ÷ 60.5 × 100 = 61.157%
  4. Check: Work backwards: 0.61157 × 60.5 = 37, the gap between the values.

In a spreadsheet: =ABS(42-79)/((42+79)/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

79 is 37 more than 42. Measured against their average, 60.5, that gap is 61.157%. The result is the same whichever value you name first.

Prices: if one shop charges $42 and another $79 for the same item, the prices differ by 61.157%.

Why the average is the base

Dividing the gap of 37 by 42 gives 88.0952%, and dividing it by 79 gives 46.8354%. The average, 60.5, sits between them, so the result does not depend on which value is listed first.
