How to work it out

  1. Difference: 15 − 22 = -7
  2. Divide by the starting value: -7 ÷ 22 = -0.318182
  3. Multiply by 100: -31.8182%
  4. Check: Work forwards from the start: 22 × (1 − 0.318182) = 22 × 0.681818 = 15.

In a spreadsheet: =(15-22)/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 68.1818% of the old one: for every 100 at the start there are now 68.1818, so 31.8182 out of every 100 have gone.

Sales: a price cut from $22 to $15 is a 31.8182% discount.

Why the change back is different

A 31.8182% fall followed by a 31.8182% rise does not bring you back to 22: it gives 19.7727. The second percentage is taken of 15, not of 22, so to undo this change you need 46.6667% instead.
