How to work it out

  1. Difference: 24 − 73 = -49
  2. Divide by the starting value: -49 ÷ 73 = -0.671233
  3. Multiply by 100: -67.1233%
  4. Check: Work forwards from the start: 73 × (1 − 0.671233) = 73 × 0.328767 = 24.

In a spreadsheet: =(24-73)/73*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 32.8767% of the old one: for every 100 at the start there are now 32.8767, so 67.1233 out of every 100 have gone.

Sales: a price cut from $73 to $24 is a 67.1233% discount.

Why the change back is different

A 67.1233% fall followed by a 67.1233% rise does not bring you back to 73: it gives 40.1096. The second percentage is taken of 24, not of 73, so to undo this change you need 204.1667% instead.
