How to work it out

  1. Difference: 17 − 88 = -71
  2. Divide by the starting value: -71 ÷ 88 = -0.806818
  3. Multiply by 100: -80.6818%
  4. Check: Work forwards from the start: 88 × (1 − 0.806818) = 88 × 0.193182 = 17.

In a spreadsheet: =(17-88)/88*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 19.3182% of the old one: for every 100 at the start there are now 19.3182, so 80.6818 out of every 100 have gone.

Sales: a price cut from $88 to $17 is a 80.6818% discount.

Why the change back is different

A 80.6818% fall followed by a 80.6818% rise does not bring you back to 88: it gives 30.7159. The second percentage is taken of 17, not of 88, so to undo this change you need 417.6471% instead.
