How to work it out

  1. Gap between the values: |20 − 70| = 50
  2. Average of the values: (20 + 70) ÷ 2 = 45
  3. Divide the gap by the average and multiply by 100: 50 ÷ 45 × 100 = 111.1111%
  4. Check: Work backwards: 1.111111 × 45 = 50, the gap between the values.

In a spreadsheet: =ABS(20-70)/((20+70)/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

70 is 50 more than 20. Measured against their average, 45, that gap is 111.1111%. The result is the same whichever value you name first.

Prices: if one shop charges $20 and another $70 for the same item, the prices differ by 111.1111%.

Why the average is the base

Dividing the gap of 50 by 20 gives 250%, and dividing it by 70 gives 71.4286%. The average, 45, sits between them, so the result does not depend on which value is listed first.
