How to work it out

  1. Difference: 15 − 92 = -77
  2. Divide by the starting value: -77 ÷ 92 = -0.836957
  3. Multiply by 100: -83.6957%
  4. Check: Work forwards from the start: 92 × (1 − 0.836957) = 92 × 0.163043 = 15.

In a spreadsheet: =(15-92)/92*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 16.3043% of the old one: for every 100 at the start there are now 16.3043, so 83.6957 out of every 100 have gone.

Sales: a price cut from $92 to $15 is a 83.6957% discount.

Why the change back is different

A 83.6957% fall followed by a 83.6957% rise does not bring you back to 92: it gives 27.5543. The second percentage is taken of 15, not of 92, so to undo this change you need 513.3333% instead.
