How to work it out

  1. Difference: 18 − 41 = -23
  2. Divide by the starting value: -23 ÷ 41 = -0.560976
  3. Multiply by 100: -56.0976%
  4. Check: Work forwards from the start: 41 × (1 − 0.560976) = 41 × 0.439024 = 18.

In a spreadsheet: =(18-41)/41*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 43.9024% of the old one: for every 100 at the start there are now 43.9024, so 56.0976 out of every 100 have gone.

Sales: a price cut from $41 to $18 is a 56.0976% discount.

Why the change back is different

A 56.0976% fall followed by a 56.0976% rise does not bring you back to 41: it gives 28.0976. The second percentage is taken of 18, not of 41, so to undo this change you need 127.7778% instead.
