How to work it out

  1. Difference: 31 − 98 = -67
  2. Divide by the starting value: -67 ÷ 98 = -0.683673
  3. Multiply by 100: -68.3673%
  4. Check: Work forwards from the start: 98 × (1 − 0.683673) = 98 × 0.316327 = 31.

In a spreadsheet: =(31-98)/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 31.6327% of the old one: for every 100 at the start there are now 31.6327, so 68.3673 out of every 100 have gone.

Sales: a price cut from $98 to $31 is a 68.3673% discount.

Why the change back is different

A 68.3673% fall followed by a 68.3673% rise does not bring you back to 98: it gives 52.1939. The second percentage is taken of 31, not of 98, so to undo this change you need 216.129% instead.
