How to work it out

  1. Difference: 41 − 80 = -39
  2. Divide by the starting value: -39 ÷ 80 = -0.4875
  3. Multiply by 100: -48.75%
  4. Check: Work forwards from the start: 80 × (1 − 0.4875) = 80 × 0.5125 = 41.

In a spreadsheet: =(41-80)/80*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 51.25% of the old one: for every 100 at the start there are now 51.25, so 48.75 out of every 100 have gone.

Sales: a price cut from $80 to $41 is a 48.75% discount.

Why the change back is different

A 48.75% fall followed by a 48.75% rise does not bring you back to 80: it gives 60.9875. The second percentage is taken of 41, not of 80, so to undo this change you need 95.122% instead.
