How to work it out

  1. Gap between the values: |34 − 68| = 34
  2. Average of the values: (34 + 68) ÷ 2 = 51
  3. Divide the gap by the average and multiply by 100: 34 ÷ 51 × 100 = 66.6667%
  4. Check: Work backwards: 0.666667 × 51 = 34, the gap between the values.

In a spreadsheet: =ABS(34-68)/((34+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 34 more than 34. Measured against their average, 51, that gap is 66.6667%. The result is the same whichever value you name first.

Prices: if one shop charges $34 and another $68 for the same item, the prices differ by 66.6667%.

Why the average is the base

Dividing the gap of 34 by 34 gives 100%, and dividing it by 68 gives 50%. The average, 51, sits between them, so the result does not depend on which value is listed first.
