How to work it out
- Gap between the values: |20 − 25| = 5
- Average of the values: (20 + 25) ÷ 2 = 22.5
- Divide the gap by the average and multiply by 100: 5 ÷ 22.5 × 100 = 22.2222%
- Check: Work backwards: 0.222222 × 22.5 = 5, the gap between the values.
In a spreadsheet: =ABS(20-25)/((20+25)/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
25 is 5 more than 20. Measured against their average, 22.5, that gap is 22.2222%. The result is the same whichever value you name first.
Prices: if one shop charges $20 and another $25 for the same item, the prices differ by 22.2222%.
Why the average is the base
Dividing the gap of 5 by 20 gives 25%, and dividing it by 25 gives 20%. The average, 22.5, sits between them, so the result does not depend on which value is listed first.
