How to work it out

  1. Difference: 9 − 33 = -24
  2. Divide by the starting value: -24 ÷ 33 = -0.727273
  3. Multiply by 100: -72.7273%
  4. Check: Work forwards from the start: 33 × (1 − 0.727273) = 33 × 0.272727 = 9.

In a spreadsheet: =(9-33)/33*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 27.2727% of the old one: for every 100 at the start there are now 27.2727, so 72.7273 out of every 100 have gone.

Sales: a price cut from $33 to $9 is a 72.7273% discount.

Why the change back is different

A 72.7273% fall followed by a 72.7273% rise does not bring you back to 33: it gives 15.5455. The second percentage is taken of 9, not of 33, so to undo this change you need 266.6667% instead.
