How to work it out

  1. Gap between the values: |49 − 51| = 2
  2. Average of the values: (49 + 51) ÷ 2 = 50
  3. Divide the gap by the average and multiply by 100: 2 ÷ 50 × 100 = 4%
  4. Check: Work backwards: 0.04 × 50 = 2, the gap between the values.

In a spreadsheet: =ABS(49-51)/((49+51)/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

51 is 2 more than 49. Measured against their average, 50, that gap is 4%. The result is the same whichever value you name first.

Prices: if one shop charges $49 and another $51 for the same item, the prices differ by 4%.

Why the average is the base

Dividing the gap of 2 by 49 gives 4.0816%, and dividing it by 51 gives 3.9216%. The average, 50, sits between them, so the result does not depend on which value is listed first.
