How to work it out

  1. Difference: 84 − 41 = 43
  2. Divide by the starting value: 43 ÷ 41 = 1.04878
  3. Multiply by 100: 104.878%
  4. Check: Work forwards from the start: 41 × (1 + 1.04878) = 41 × 2.04878 = 84.

In a spreadsheet: =(84-41)/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 2.0488 times the old one: for every 100 at the start there are now 204.878. The value has more than doubled.

Prices: an item whose price rises from $41 to $84 has gone up by 104.878%.

Why the change back is different

A 104.878% rise followed by a 104.878% fall does not bring you back to 41: it gives -4.0976. The second percentage is taken of 84, not of 41, so to undo this change you need 51.1905% instead.
