How to work it out

  1. Gap between the values: |70 − 80| = 10
  2. Average of the values: (70 + 80) ÷ 2 = 75
  3. Divide the gap by the average and multiply by 100: 10 ÷ 75 × 100 = 13.3333%
  4. Check: Work backwards: 0.133333 × 75 = 10, the gap between the values.

In a spreadsheet: =ABS(70-80)/((70+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 10 more than 70. Measured against their average, 75, that gap is 13.3333%. The result is the same whichever value you name first.

Prices: if one shop charges $70 and another $80 for the same item, the prices differ by 13.3333%.

Why the average is the base

Dividing the gap of 10 by 70 gives 14.2857%, and dividing it by 80 gives 12.5%. The average, 75, sits between them, so the result does not depend on which value is listed first.
