How to work it out

  1. Gap between the values: |70 − 100| = 30
  2. Average of the values: (70 + 100) ÷ 2 = 85
  3. Divide the gap by the average and multiply by 100: 30 ÷ 85 × 100 = 35.2941%
  4. Check: Work backwards: 0.352941 × 85 = 30, the gap between the values.

In a spreadsheet: =ABS(70-100)/((70+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 30 more than 70. Measured against their average, 85, that gap is 35.2941%. The result is the same whichever value you name first.

Prices: if one shop charges $70 and another $100 for the same item, the prices differ by 35.2941%.

Why the average is the base

Dividing the gap of 30 by 70 gives 42.8571%, and dividing it by 100 gives 30%. The average, 85, sits between them, so the result does not depend on which value is listed first.
