How to work it out

  1. Gap between the values: |55 − 56| = 1
  2. Average of the values: (55 + 56) ÷ 2 = 55.5
  3. Divide the gap by the average and multiply by 100: 1 ÷ 55.5 × 100 = 1.8018%
  4. Check: Work backwards: 0.018018 × 55.5 = 1, the gap between the values.

In a spreadsheet: =ABS(55-56)/((55+56)/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

56 is 1 more than 55. Measured against their average, 55.5, that gap is 1.8018%. The result is the same whichever value you name first.

Prices: if one shop charges $55 and another $56 for the same item, the prices differ by 1.8018%.

Why the average is the base

Dividing the gap of 1 by 55 gives 1.8182%, and dividing it by 56 gives 1.7857%. The average, 55.5, sits between them, so the result does not depend on which value is listed first.
