How to work it out

  1. Difference: 45 − 22 = 23
  2. Divide by the starting value: 23 ÷ 22 = 1.045455
  3. Multiply by 100: 104.5455%
  4. Check: Work forwards from the start: 22 × (1 + 1.045455) = 22 × 2.045455 = 45.

In a spreadsheet: =(45-22)/22*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 2.0455 times the old one: for every 100 at the start there are now 204.5455. The value has more than doubled.

Prices: an item whose price rises from $22 to $45 has gone up by 104.5455%.

Why the change back is different

A 104.5455% rise followed by a 104.5455% fall does not bring you back to 22: it gives -2.0455. The second percentage is taken of 45, not of 22, so to undo this change you need 51.1111% instead.
