How to work it out

  1. Difference: 21 − 44 = -23
  2. Divide by the starting value: -23 ÷ 44 = -0.522727
  3. Multiply by 100: -52.2727%
  4. Check: Work forwards from the start: 44 × (1 − 0.522727) = 44 × 0.477273 = 21.

In a spreadsheet: =(21-44)/44*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 47.7273% of the old one: for every 100 at the start there are now 47.7273, so 52.2727 out of every 100 have gone.

Sales: a price cut from $44 to $21 is a 52.2727% discount.

Why the change back is different

A 52.2727% fall followed by a 52.2727% rise does not bring you back to 44: it gives 31.9773. The second percentage is taken of 21, not of 44, so to undo this change you need 109.5238% instead.
