How to work it out

  1. Difference: 34 − 57 = -23
  2. Divide by the starting value: -23 ÷ 57 = -0.403509
  3. Multiply by 100: -40.3509%
  4. Check: Work forwards from the start: 57 × (1 − 0.403509) = 57 × 0.596491 = 34.

In a spreadsheet: =(34-57)/57*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 59.6491% of the old one: for every 100 at the start there are now 59.6491, so 40.3509 out of every 100 have gone.

Sales: a price cut from $57 to $34 is a 40.3509% discount.

Why the change back is different

A 40.3509% fall followed by a 40.3509% rise does not bring you back to 57: it gives 47.7193. The second percentage is taken of 34, not of 57, so to undo this change you need 67.6471% instead.
