How to work it out
- Gap between the values: |50 − 90| = 40
- Average of the values: (50 + 90) ÷ 2 = 70
- Divide the gap by the average and multiply by 100: 40 ÷ 70 × 100 = 57.1429%
- Check: Work backwards: 0.571429 × 70 = 40, the gap between the values.
In a spreadsheet: =ABS(50-90)/((50+90)/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
90 is 40 more than 50. Measured against their average, 70, that gap is 57.1429%. The result is the same whichever value you name first.
Prices: if one shop charges $50 and another $90 for the same item, the prices differ by 57.1429%.
Why the average is the base
Dividing the gap of 40 by 50 gives 80%, and dividing it by 90 gives 44.4444%. The average, 70, sits between them, so the result does not depend on which value is listed first.
