How to work it out

  1. Difference: 38 − 18 = 20
  2. Divide by the starting value: 20 ÷ 18 = 1.111111
  3. Multiply by 100: 111.1111%
  4. Check: Work forwards from the start: 18 × (1 + 1.111111) = 18 × 2.111111 = 38.

In a spreadsheet: =(38-18)/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 2.1111 times the old one: for every 100 at the start there are now 211.1111. The value has more than doubled.

Prices: an item whose price rises from $18 to $38 has gone up by 111.1111%.

Why the change back is different

A 111.1111% rise followed by a 111.1111% fall does not bring you back to 18: it gives -4.2222. The second percentage is taken of 38, not of 18, so to undo this change you need 52.6316% instead.
