How to work it out

  1. Difference: 43 − 83 = -40
  2. Divide by the starting value: -40 ÷ 83 = -0.481928
  3. Multiply by 100: -48.1928%
  4. Check: Work forwards from the start: 83 × (1 − 0.481928) = 83 × 0.518072 = 43.

In a spreadsheet: =(43-83)/83*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 51.8072% of the old one: for every 100 at the start there are now 51.8072, so 48.1928 out of every 100 have gone.

Sales: a price cut from $83 to $43 is a 48.1928% discount.

Why the change back is different

A 48.1928% fall followed by a 48.1928% rise does not bring you back to 83: it gives 63.7229. The second percentage is taken of 43, not of 83, so to undo this change you need 93.0233% instead.
