How to work it out

  1. Difference: 12 − 28 = -16
  2. Divide by the starting value: -16 ÷ 28 = -0.571429
  3. Multiply by 100: -57.1429%
  4. Check: Work forwards from the start: 28 × (1 − 0.571429) = 28 × 0.428571 = 12.

In a spreadsheet: =(12-28)/28*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 42.8571% of the old one: for every 100 at the start there are now 42.8571, so 57.1429 out of every 100 have gone.

Sales: a price cut from $28 to $12 is a 57.1429% discount.

Why the change back is different

A 57.1429% fall followed by a 57.1429% rise does not bring you back to 28: it gives 18.8571. The second percentage is taken of 12, not of 28, so to undo this change you need 133.3333% instead.
