How to work it out

  1. Difference: 28 − 43 = -15
  2. Divide by the starting value: -15 ÷ 43 = -0.348837
  3. Multiply by 100: -34.8837%
  4. Check: Work forwards from the start: 43 × (1 − 0.348837) = 43 × 0.651163 = 28.

In a spreadsheet: =(28-43)/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 65.1163% of the old one: for every 100 at the start there are now 65.1163, so 34.8837 out of every 100 have gone.

Sales: a price cut from $43 to $28 is a 34.8837% discount.

Why the change back is different

A 34.8837% fall followed by a 34.8837% rise does not bring you back to 43: it gives 37.7674. The second percentage is taken of 28, not of 43, so to undo this change you need 53.5714% instead.
