How to work it out
- Gap between the values: |18 − 75| = 57
- Average of the values: (18 + 75) ÷ 2 = 46.5
- Divide the gap by the average and multiply by 100: 57 ÷ 46.5 × 100 = 122.5806%
- Check: Work backwards: 1.225806 × 46.5 = 57, the gap between the values.
In a spreadsheet: =ABS(18-75)/((18+75)/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
