How to work it out

  1. Difference: 13 − 25 = -12
  2. Divide by the starting value: -12 ÷ 25 = -0.48
  3. Multiply by 100: -48%
  4. Check: Work forwards from the start: 25 × (1 − 0.48) = 25 × 0.52 = 13.

In a spreadsheet: =(13-25)/25*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 52% of the old one: for every 100 at the start there are now 52, so 48 out of every 100 have gone.

Sales: a price cut from $25 to $13 is a 48% discount.

Why the change back is different

A 48% fall followed by a 48% rise does not bring you back to 25: it gives 19.24. The second percentage is taken of 13, not of 25, so to undo this change you need 92.3077% instead.
