How to work it out

  1. Difference: 15 − 54 = -39
  2. Divide by the starting value: -39 ÷ 54 = -0.722222
  3. Multiply by 100: -72.2222%
  4. Check: Work forwards from the start: 54 × (1 − 0.722222) = 54 × 0.277778 = 15.

In a spreadsheet: =(15-54)/54*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 27.7778% of the old one: for every 100 at the start there are now 27.7778, so 72.2222 out of every 100 have gone.

Sales: a price cut from $54 to $15 is a 72.2222% discount.

Why the change back is different

A 72.2222% fall followed by a 72.2222% rise does not bring you back to 54: it gives 25.8333. The second percentage is taken of 15, not of 54, so to undo this change you need 260% instead.
