How to work it out

  1. Difference: 28 − 65 = -37
  2. Divide by the starting value: -37 ÷ 65 = -0.569231
  3. Multiply by 100: -56.9231%
  4. Check: Work forwards from the start: 65 × (1 − 0.569231) = 65 × 0.430769 = 28.

In a spreadsheet: =(28-65)/65*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 43.0769% of the old one: for every 100 at the start there are now 43.0769, so 56.9231 out of every 100 have gone.

Sales: a price cut from $65 to $28 is a 56.9231% discount.

Why the change back is different

A 56.9231% fall followed by a 56.9231% rise does not bring you back to 65: it gives 43.9385. The second percentage is taken of 28, not of 65, so to undo this change you need 132.1429% instead.
