How to work it out

  1. Difference: 10 − 54 = -44
  2. Divide by the starting value: -44 ÷ 54 = -0.814815
  3. Multiply by 100: -81.4815%
  4. Check: Work forwards from the start: 54 × (1 − 0.814815) = 54 × 0.185185 = 10.

In a spreadsheet: =(10-54)/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 18.5185% of the old one: for every 100 at the start there are now 18.5185, so 81.4815 out of every 100 have gone.

Sales: a price cut from $54 to $10 is a 81.4815% discount.

Why the change back is different

A 81.4815% fall followed by a 81.4815% rise does not bring you back to 54: it gives 18.1481. The second percentage is taken of 10, not of 54, so to undo this change you need 440% instead.
