How to work it out

  1. Difference: 17 − 98 = -81
  2. Divide by the starting value: -81 ÷ 98 = -0.826531
  3. Multiply by 100: -82.6531%
  4. Check: Work forwards from the start: 98 × (1 − 0.826531) = 98 × 0.173469 = 17.

In a spreadsheet: =(17-98)/98*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 17.3469% of the old one: for every 100 at the start there are now 17.3469, so 82.6531 out of every 100 have gone.

Sales: a price cut from $98 to $17 is a 82.6531% discount.

Why the change back is different

A 82.6531% fall followed by a 82.6531% rise does not bring you back to 98: it gives 31.051. The second percentage is taken of 17, not of 98, so to undo this change you need 476.4706% instead.
