How to work it out

  1. Difference: 7 − 22 = -15
  2. Divide by the starting value: -15 ÷ 22 = -0.681818
  3. Multiply by 100: -68.1818%
  4. Check: Work forwards from the start: 22 × (1 − 0.681818) = 22 × 0.318182 = 7.

In a spreadsheet: =(7-22)/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 31.8182% of the old one: for every 100 at the start there are now 31.8182, so 68.1818 out of every 100 have gone.

Sales: a price cut from $22 to $7 is a 68.1818% discount.

Why the change back is different

A 68.1818% fall followed by a 68.1818% rise does not bring you back to 22: it gives 11.7727. The second percentage is taken of 7, not of 22, so to undo this change you need 214.2857% instead.
