How to work it out

  1. Difference: 33 − 81 = -48
  2. Divide by the starting value: -48 ÷ 81 = -0.592593
  3. Multiply by 100: -59.2593%
  4. Check: Work forwards from the start: 81 × (1 − 0.592593) = 81 × 0.407407 = 33.

In a spreadsheet: =(33-81)/81*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 40.7407% of the old one: for every 100 at the start there are now 40.7407, so 59.2593 out of every 100 have gone.

Sales: a price cut from $81 to $33 is a 59.2593% discount.

Why the change back is different

A 59.2593% fall followed by a 59.2593% rise does not bring you back to 81: it gives 52.5556. The second percentage is taken of 33, not of 81, so to undo this change you need 145.4545% instead.
