How to work it out

  1. Gap between the values: |50 − 100| = 50
  2. Average of the values: (50 + 100) ÷ 2 = 75
  3. Divide the gap by the average and multiply by 100: 50 ÷ 75 × 100 = 66.6667%
  4. Check: Work backwards: 0.666667 × 75 = 50, the gap between the values.

In a spreadsheet: =ABS(50-100)/((50+100)/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

100 is 50 more than 50. Measured against their average, 75, that gap is 66.6667%. The result is the same whichever value you name first.

Prices: if one shop charges $50 and another $100 for the same item, the prices differ by 66.6667%.

Why the average is the base

Dividing the gap of 50 by 50 gives 100%, and dividing it by 100 gives 50%. The average, 75, sits between them, so the result does not depend on which value is listed first.
