How to work it out

  1. Difference: 33 − 78 = -45
  2. Divide by the starting value: -45 ÷ 78 = -0.576923
  3. Multiply by 100: -57.6923%
  4. Check: Work forwards from the start: 78 × (1 − 0.576923) = 78 × 0.423077 = 33.

In a spreadsheet: =(33-78)/78*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 42.3077% of the old one: for every 100 at the start there are now 42.3077, so 57.6923 out of every 100 have gone.

Sales: a price cut from $78 to $33 is a 57.6923% discount.

Why the change back is different

A 57.6923% fall followed by a 57.6923% rise does not bring you back to 78: it gives 52.0385. The second percentage is taken of 33, not of 78, so to undo this change you need 136.3636% instead.
