How to work it out

  1. Difference: 65 − 99 = -34
  2. Divide by the starting value: -34 ÷ 99 = -0.343434
  3. Multiply by 100: -34.3434%
  4. Check: Work forwards from the start: 99 × (1 − 0.343434) = 99 × 0.656566 = 65.

In a spreadsheet: =(65-99)/99*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 65.6566% of the old one: for every 100 at the start there are now 65.6566, so 34.3434 out of every 100 have gone.

Sales: a price cut from $99 to $65 is a 34.3434% discount.

Why the change back is different

A 34.3434% fall followed by a 34.3434% rise does not bring you back to 99: it gives 87.3232. The second percentage is taken of 65, not of 99, so to undo this change you need 52.3077% instead.
