How to work it out

  1. Difference: 20 − 43 = -23
  2. Divide by the starting value: -23 ÷ 43 = -0.534884
  3. Multiply by 100: -53.4884%
  4. Check: Work forwards from the start: 43 × (1 − 0.534884) = 43 × 0.465116 = 20.

In a spreadsheet: =(20-43)/43*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 46.5116% of the old one: for every 100 at the start there are now 46.5116, so 53.4884 out of every 100 have gone.

Sales: a price cut from $43 to $20 is a 53.4884% discount.

Why the change back is different

A 53.4884% fall followed by a 53.4884% rise does not bring you back to 43: it gives 30.6977. The second percentage is taken of 20, not of 43, so to undo this change you need 115% instead.
