How to work it out

  1. Gap between the values: |90 − 98| = 8
  2. Average of the values: (90 + 98) ÷ 2 = 94
  3. Divide the gap by the average and multiply by 100: 8 ÷ 94 × 100 = 8.5106%
  4. Check: Work backwards: 0.085106 × 94 = 8, the gap between the values.

In a spreadsheet: =ABS(90-98)/((90+98)/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

98 is 8 more than 90. Measured against their average, 94, that gap is 8.5106%. The result is the same whichever value you name first.

Prices: if one shop charges $90 and another $98 for the same item, the prices differ by 8.5106%.

Why the average is the base

Dividing the gap of 8 by 90 gives 8.8889%, and dividing it by 98 gives 8.1633%. The average, 94, sits between them, so the result does not depend on which value is listed first.
