How to work it out

  1. Difference: 4 − 22 = -18
  2. Divide by the starting value: -18 ÷ 22 = -0.818182
  3. Multiply by 100: -81.8182%
  4. Check: Work forwards from the start: 22 × (1 − 0.818182) = 22 × 0.181818 = 4.

In a spreadsheet: =(4-22)/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 18.1818% of the old one: for every 100 at the start there are now 18.1818, so 81.8182 out of every 100 have gone.

Sales: a price cut from $22 to $4 is a 81.8182% discount.

Why the change back is different

A 81.8182% fall followed by a 81.8182% rise does not bring you back to 22: it gives 7.2727. The second percentage is taken of 4, not of 22, so to undo this change you need 450% instead.
