How to work it out

  1. Difference: 28 − 33 = -5
  2. Divide by the starting value: -5 ÷ 33 = -0.151515
  3. Multiply by 100: -15.1515%
  4. Check: Work forwards from the start: 33 × (1 − 0.151515) = 33 × 0.848485 = 28.

In a spreadsheet: =(28-33)/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 84.8485% of the old one: for every 100 at the start there are now 84.8485, so 15.1515 out of every 100 have gone.

Sales: a price cut from $33 to $28 is a 15.1515% discount.

Why the change back is different

A 15.1515% fall followed by a 15.1515% rise does not bring you back to 33: it gives 32.2424. The second percentage is taken of 28, not of 33, so to undo this change you need 17.8571% instead.
