How to work it out

  1. Difference: 17 − 56 = -39
  2. Divide by the starting value: -39 ÷ 56 = -0.696429
  3. Multiply by 100: -69.6429%
  4. Check: Work forwards from the start: 56 × (1 − 0.696429) = 56 × 0.303571 = 17.

In a spreadsheet: =(17-56)/56*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 30.3571% of the old one: for every 100 at the start there are now 30.3571, so 69.6429 out of every 100 have gone.

Sales: a price cut from $56 to $17 is a 69.6429% discount.

Why the change back is different

A 69.6429% fall followed by a 69.6429% rise does not bring you back to 56: it gives 28.8393. The second percentage is taken of 17, not of 56, so to undo this change you need 229.4118% instead.
