How to work it out

  1. Gap between the values: |7 − 78| = 71
  2. Average of the values: (7 + 78) ÷ 2 = 42.5
  3. Divide the gap by the average and multiply by 100: 71 ÷ 42.5 × 100 = 167.0588%
  4. Check: Work backwards: 1.670588 × 42.5 = 71, the gap between the values.

In a spreadsheet: =ABS(7-78)/((7+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 71 more than 7. Measured against their average, 42.5, that gap is 167.0588%. The result is the same whichever value you name first.

Prices: if one shop charges $7 and another $78 for the same item, the prices differ by 167.0588%.

Why the average is the base

Dividing the gap of 71 by 7 gives 1,014.2857%, and dividing it by 78 gives 91.0256%. The average, 42.5, sits between them, so the result does not depend on which value is listed first.
