How to work it out

  1. Gap between the values: |1 − 81| = 80
  2. Average of the values: (1 + 81) ÷ 2 = 41
  3. Divide the gap by the average and multiply by 100: 80 ÷ 41 × 100 = 195.122%
  4. Check: Work backwards: 1.95122 × 41 = 80, the gap between the values.

In a spreadsheet: =ABS(1-81)/((1+81)/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

81 is 80 more than 1. Measured against their average, 41, that gap is 195.122%. The result is the same whichever value you name first.

Prices: if one shop charges $1 and another $81 for the same item, the prices differ by 195.122%.

Why the average is the base

Dividing the gap of 80 by 1 gives 8,000%, and dividing it by 81 gives 98.7654%. The average, 41, sits between them, so the result does not depend on which value is listed first.
