How to work it out

  1. Difference: 41 − 18 = 23
  2. Divide by the starting value: 23 ÷ 18 = 1.277778
  3. Multiply by 100: 127.7778%
  4. Check: Work forwards from the start: 18 × (1 + 1.277778) = 18 × 2.277778 = 41.

In a spreadsheet: =(41-18)/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 2.2778 times the old one: for every 100 at the start there are now 227.7778. The value has more than doubled.

Prices: an item whose price rises from $18 to $41 has gone up by 127.7778%.

Why the change back is different

A 127.7778% rise followed by a 127.7778% fall does not bring you back to 18: it gives -11.3889. The second percentage is taken of 41, not of 18, so to undo this change you need 56.0976% instead.
