How to work it out

  1. Difference: 19 − 54 = -35
  2. Divide by the starting value: -35 ÷ 54 = -0.648148
  3. Multiply by 100: -64.8148%
  4. Check: Work forwards from the start: 54 × (1 − 0.648148) = 54 × 0.351852 = 19.

In a spreadsheet: =(19-54)/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 35.1852% of the old one: for every 100 at the start there are now 35.1852, so 64.8148 out of every 100 have gone.

Sales: a price cut from $54 to $19 is a 64.8148% discount.

Why the change back is different

A 64.8148% fall followed by a 64.8148% rise does not bring you back to 54: it gives 31.3148. The second percentage is taken of 19, not of 54, so to undo this change you need 184.2105% instead.
