How to work it out

  1. Gap between the values: |7 − 45| = 38
  2. Average of the values: (7 + 45) ÷ 2 = 26
  3. Divide the gap by the average and multiply by 100: 38 ÷ 26 × 100 = 146.1538%
  4. Check: Work backwards: 1.461538 × 26 = 38, the gap between the values.

In a spreadsheet: =ABS(7-45)/((7+45)/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

45 is 38 more than 7. Measured against their average, 26, that gap is 146.1538%. The result is the same whichever value you name first.

Prices: if one shop charges $7 and another $45 for the same item, the prices differ by 146.1538%.

Why the average is the base

Dividing the gap of 38 by 7 gives 542.8571%, and dividing it by 45 gives 84.4444%. The average, 26, sits between them, so the result does not depend on which value is listed first.
