How to work it out

  1. Difference: 9 − 65 = -56
  2. Divide by the starting value: -56 ÷ 65 = -0.861538
  3. Multiply by 100: -86.1538%
  4. Check: Work forwards from the start: 65 × (1 − 0.861538) = 65 × 0.138462 = 9.

In a spreadsheet: =(9-65)/65*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 13.8462% of the old one: for every 100 at the start there are now 13.8462, so 86.1538 out of every 100 have gone.

Sales: a price cut from $65 to $9 is a 86.1538% discount.

Why the change back is different

A 86.1538% fall followed by a 86.1538% rise does not bring you back to 65: it gives 16.7538. The second percentage is taken of 9, not of 65, so to undo this change you need 622.2222% instead.
