How to work it out

  1. Difference: 23 − 54 = -31
  2. Divide by the starting value: -31 ÷ 54 = -0.574074
  3. Multiply by 100: -57.4074%
  4. Check: Work forwards from the start: 54 × (1 − 0.574074) = 54 × 0.425926 = 23.

In a spreadsheet: =(23-54)/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 42.5926% of the old one: for every 100 at the start there are now 42.5926, so 57.4074 out of every 100 have gone.

Sales: a price cut from $54 to $23 is a 57.4074% discount.

Why the change back is different

A 57.4074% fall followed by a 57.4074% rise does not bring you back to 54: it gives 36.2037. The second percentage is taken of 23, not of 54, so to undo this change you need 134.7826% instead.
