How to work it out

  1. Difference: 17 − 93 = -76
  2. Divide by the starting value: -76 ÷ 93 = -0.817204
  3. Multiply by 100: -81.7204%
  4. Check: Work forwards from the start: 93 × (1 − 0.817204) = 93 × 0.182796 = 17.

In a spreadsheet: =(17-93)/93*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 18.2796% of the old one: for every 100 at the start there are now 18.2796, so 81.7204 out of every 100 have gone.

Sales: a price cut from $93 to $17 is a 81.7204% discount.

Why the change back is different

A 81.7204% fall followed by a 81.7204% rise does not bring you back to 93: it gives 30.8925. The second percentage is taken of 17, not of 93, so to undo this change you need 447.0588% instead.
