How to work it out

  1. Gap between the values: |10 − 80| = 70
  2. Average of the values: (10 + 80) ÷ 2 = 45
  3. Divide the gap by the average and multiply by 100: 70 ÷ 45 × 100 = 155.5556%
  4. Check: Work backwards: 1.555556 × 45 = 70, the gap between the values.

In a spreadsheet: =ABS(10-80)/((10+80)/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

80 is 70 more than 10. Measured against their average, 45, that gap is 155.5556%. The result is the same whichever value you name first.

Prices: if one shop charges $10 and another $80 for the same item, the prices differ by 155.5556%.

Why the average is the base

Dividing the gap of 70 by 10 gives 700%, and dividing it by 80 gives 87.5%. The average, 45, sits between them, so the result does not depend on which value is listed first.
