How to work it out

  1. Gap between the values: |17 − 68| = 51
  2. Average of the values: (17 + 68) ÷ 2 = 42.5
  3. Divide the gap by the average and multiply by 100: 51 ÷ 42.5 × 100 = 120%
  4. Check: Work backwards: 1.2 × 42.5 = 51, the gap between the values.

In a spreadsheet: =ABS(17-68)/((17+68)/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

68 is 51 more than 17. Measured against their average, 42.5, that gap is 120%. The result is the same whichever value you name first.

Prices: if one shop charges $17 and another $68 for the same item, the prices differ by 120%.

Why the average is the base

Dividing the gap of 51 by 17 gives 300%, and dividing it by 68 gives 75%. The average, 42.5, sits between them, so the result does not depend on which value is listed first.
