How to work it out

  1. Difference: 98 − 18 = 80
  2. Divide by the starting value: 80 ÷ 18 = 4.444444
  3. Multiply by 100: 444.4444%
  4. Check: Work forwards from the start: 18 × (1 + 4.444444) = 18 × 5.444444 = 98.

In a spreadsheet: =(98-18)/18*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 5.4444 times the old one: for every 100 at the start there are now 544.4444. The value has more than doubled.

Prices: an item whose price rises from $18 to $98 has gone up by 444.4444%.

Why the change back is different

A 444.4444% rise followed by a 444.4444% fall does not bring you back to 18: it gives -337.5556. The second percentage is taken of 98, not of 18, so to undo this change you need 81.6327% instead.
