How to work it out

  1. Difference: 31 − 92 = -61
  2. Divide by the starting value: -61 ÷ 92 = -0.663043
  3. Multiply by 100: -66.3043%
  4. Check: Work forwards from the start: 92 × (1 − 0.663043) = 92 × 0.336957 = 31.

In a spreadsheet: =(31-92)/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 33.6957% of the old one: for every 100 at the start there are now 33.6957, so 66.3043 out of every 100 have gone.

Sales: a price cut from $92 to $31 is a 66.3043% discount.

Why the change back is different

A 66.3043% fall followed by a 66.3043% rise does not bring you back to 92: it gives 51.5543. The second percentage is taken of 31, not of 92, so to undo this change you need 196.7742% instead.
