How to work it out

  1. Difference: 88 − 98 = -10
  2. Divide by the starting value: -10 ÷ 98 = -0.102041
  3. Multiply by 100: -10.2041%
  4. Check: Work forwards from the start: 98 × (1 − 0.102041) = 98 × 0.897959 = 88.

In a spreadsheet: =(88-98)/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 89.7959% of the old one: for every 100 at the start there are now 89.7959, so 10.2041 out of every 100 have gone.

Sales: a price cut from $98 to $88 is a 10.2041% discount.

Why the change back is different

A 10.2041% fall followed by a 10.2041% rise does not bring you back to 98: it gives 96.9796. The second percentage is taken of 88, not of 98, so to undo this change you need 11.3636% instead.
