How to work it out

  1. Difference: 43 − 80 = -37
  2. Divide by the starting value: -37 ÷ 80 = -0.4625
  3. Multiply by 100: -46.25%
  4. Check: Work forwards from the start: 80 × (1 − 0.4625) = 80 × 0.5375 = 43.

In a spreadsheet: =(43-80)/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 53.75% of the old one: for every 100 at the start there are now 53.75, so 46.25 out of every 100 have gone.

Sales: a price cut from $80 to $43 is a 46.25% discount.

Why the change back is different

A 46.25% fall followed by a 46.25% rise does not bring you back to 80: it gives 62.8875. The second percentage is taken of 43, not of 80, so to undo this change you need 86.0465% instead.
