How to work it out

  1. Difference: 50 − 98 = -48
  2. Divide by the starting value: -48 ÷ 98 = -0.489796
  3. Multiply by 100: -48.9796%
  4. Check: Work forwards from the start: 98 × (1 − 0.489796) = 98 × 0.510204 = 50.

In a spreadsheet: =(50-98)/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 51.0204% of the old one: for every 100 at the start there are now 51.0204, so 48.9796 out of every 100 have gone.

Sales: a price cut from $98 to $50 is a 48.9796% discount.

Why the change back is different

A 48.9796% fall followed by a 48.9796% rise does not bring you back to 98: it gives 74.4898. The second percentage is taken of 50, not of 98, so to undo this change you need 96% instead.
