How to work it out
- Difference: 31 − 10 = 21
- Divide by the starting value: 21 ÷ 10 = 2.1
- Multiply by 100: 210%
- Check: Work forwards from the start: 10 × (1 + 2.1) = 10 × 3.1 = 31.
In a spreadsheet: =(31-10)/10*100. Always divide by the starting value, not the new one. A rise from 40 to 50 is +25%, but the fall from 50 back to 40 is −20%.
What the result means
The new value is 3.1 times the old one: for every 100 at the start there are now 310. The value has more than doubled.
Prices: an item whose price rises from $10 to $31 has gone up by 210%.
Why the change back is different
A 210% rise followed by a 210% fall does not bring you back to 10: it gives -34.1. The second percentage is taken of 31, not of 10, so to undo this change you need 67.7419% instead.
