How to work it out

  1. Difference: 54 − 9 = 45
  2. Divide by the starting value: 45 ÷ 9 = 5
  3. Multiply by 100: 500%
  4. Check: Work forwards from the start: 9 × (1 + 5) = 9 × 6 = 54.

In a spreadsheet: =(54-9)/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 6 times the old one: for every 100 at the start there are now 600. The value has more than doubled.

Prices: an item whose price rises from $9 to $54 has gone up by 500%.

Why the change back is different

A 500% rise followed by a 500% fall does not bring you back to 9: it gives -216. The second percentage is taken of 54, not of 9, so to undo this change you need 83.3333% instead.
