How to work it out

  1. Difference: 54 − 80 = -26
  2. Divide by the starting value: -26 ÷ 80 = -0.325
  3. Multiply by 100: -32.5%
  4. Check: Work forwards from the start: 80 × (1 − 0.325) = 80 × 0.675 = 54.

In a spreadsheet: =(54-80)/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 67.5% of the old one: for every 100 at the start there are now 67.5, so 32.5 out of every 100 have gone.

Sales: a price cut from $80 to $54 is a 32.5% discount.

Why the change back is different

A 32.5% fall followed by a 32.5% rise does not bring you back to 80: it gives 71.55. The second percentage is taken of 54, not of 80, so to undo this change you need 48.1481% instead.
