How to work it out

  1. Difference: 15 − 43 = -28
  2. Divide by the starting value: -28 ÷ 43 = -0.651163
  3. Multiply by 100: -65.1163%
  4. Check: Work forwards from the start: 43 × (1 − 0.651163) = 43 × 0.348837 = 15.

In a spreadsheet: =(15-43)/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 34.8837% of the old one: for every 100 at the start there are now 34.8837, so 65.1163 out of every 100 have gone.

Sales: a price cut from $43 to $15 is a 65.1163% discount.

Why the change back is different

A 65.1163% fall followed by a 65.1163% rise does not bring you back to 43: it gives 24.7674. The second percentage is taken of 15, not of 43, so to undo this change you need 186.6667% instead.
