How to work it out

  1. Difference: 46 − 89 = -43
  2. Divide by the starting value: -43 ÷ 89 = -0.483146
  3. Multiply by 100: -48.3146%
  4. Check: Work forwards from the start: 89 × (1 − 0.483146) = 89 × 0.516854 = 46.

In a spreadsheet: =(46-89)/89*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 51.6854% of the old one: for every 100 at the start there are now 51.6854, so 48.3146 out of every 100 have gone.

Sales: a price cut from $89 to $46 is a 48.3146% discount.

Why the change back is different

A 48.3146% fall followed by a 48.3146% rise does not bring you back to 89: it gives 68.2247. The second percentage is taken of 46, not of 89, so to undo this change you need 93.4783% instead.
