How to work it out

  1. Difference: 16 − 91 = -75
  2. Divide by the starting value: -75 ÷ 91 = -0.824176
  3. Multiply by 100: -82.4176%
  4. Check: Work forwards from the start: 91 × (1 − 0.824176) = 91 × 0.175824 = 16.

In a spreadsheet: =(16-91)/91*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 17.5824% of the old one: for every 100 at the start there are now 17.5824, so 82.4176 out of every 100 have gone.

Sales: a price cut from $91 to $16 is a 82.4176% discount.

Why the change back is different

A 82.4176% fall followed by a 82.4176% rise does not bring you back to 91: it gives 29.1868. The second percentage is taken of 16, not of 91, so to undo this change you need 468.75% instead.
