How to work it out

  1. Gap between the values: |85 − 89| = 4
  2. Average of the values: (85 + 89) ÷ 2 = 87
  3. Divide the gap by the average and multiply by 100: 4 ÷ 87 × 100 = 4.5977%
  4. Check: Work backwards: 0.045977 × 87 = 4, the gap between the values.

In a spreadsheet: =ABS(85-89)/((85+89)/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

89 is 4 more than 85. Measured against their average, 87, that gap is 4.5977%. The result is the same whichever value you name first.

Prices: if one shop charges $85 and another $89 for the same item, the prices differ by 4.5977%.

Why the average is the base

Dividing the gap of 4 by 85 gives 4.7059%, and dividing it by 89 gives 4.4944%. The average, 87, sits between them, so the result does not depend on which value is listed first.
