How to work it out

  1. Difference: 65 − 9 = 56
  2. Divide by the starting value: 56 ÷ 9 = 6.222222
  3. Multiply by 100: 622.2222%
  4. Check: Work forwards from the start: 9 × (1 + 6.222222) = 9 × 7.222222 = 65.

In a spreadsheet: =(65-9)/9*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 7.2222 times the old one: for every 100 at the start there are now 722.2222. The value has more than doubled.

Prices: an item whose price rises from $9 to $65 has gone up by 622.2222%.

Why the change back is different

A 622.2222% rise followed by a 622.2222% fall does not bring you back to 9: it gives -339.4444. The second percentage is taken of 65, not of 9, so to undo this change you need 86.1538% instead.
