How to work it out

  1. Difference: 43 − 91 = -48
  2. Divide by the starting value: -48 ÷ 91 = -0.527473
  3. Multiply by 100: -52.7473%
  4. Check: Work forwards from the start: 91 × (1 − 0.527473) = 91 × 0.472527 = 43.

In a spreadsheet: =(43-91)/91*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 47.2527% of the old one: for every 100 at the start there are now 47.2527, so 52.7473 out of every 100 have gone.

Sales: a price cut from $91 to $43 is a 52.7473% discount.

Why the change back is different

A 52.7473% fall followed by a 52.7473% rise does not bring you back to 91: it gives 65.6813. The second percentage is taken of 43, not of 91, so to undo this change you need 111.6279% instead.
