How to work it out

  1. Gap between the values: |61 − 80| = 19
  2. Average of the values: (61 + 80) ÷ 2 = 70.5
  3. Divide the gap by the average and multiply by 100: 19 ÷ 70.5 × 100 = 26.9504%
  4. Check: Work backwards: 0.269504 × 70.5 = 19, the gap between the values.

In a spreadsheet: =ABS(61-80)/((61+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 19 more than 61. Measured against their average, 70.5, that gap is 26.9504%. The result is the same whichever value you name first.

Prices: if one shop charges $61 and another $80 for the same item, the prices differ by 26.9504%.

Why the average is the base

Dividing the gap of 19 by 61 gives 31.1475%, and dividing it by 80 gives 23.75%. The average, 70.5, sits between them, so the result does not depend on which value is listed first.
