How to work it out

  1. Gap between the values: |10 − 17| = 7
  2. Average of the values: (10 + 17) ÷ 2 = 13.5
  3. Divide the gap by the average and multiply by 100: 7 ÷ 13.5 × 100 = 51.8519%
  4. Check: Work backwards: 0.518519 × 13.5 = 7, the gap between the values.

In a spreadsheet: =ABS(10-17)/((10+17)/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

17 is 7 more than 10. Measured against their average, 13.5, that gap is 51.8519%. The result is the same whichever value you name first.

Prices: if one shop charges $10 and another $17 for the same item, the prices differ by 51.8519%.

Why the average is the base

Dividing the gap of 7 by 10 gives 70%, and dividing it by 17 gives 41.1765%. The average, 13.5, sits between them, so the result does not depend on which value is listed first.
