How to work it out

  1. Difference: 44 − 90 = -46
  2. Divide by the starting value: -46 ÷ 90 = -0.511111
  3. Multiply by 100: -51.1111%
  4. Check: Work forwards from the start: 90 × (1 − 0.511111) = 90 × 0.488889 = 44.

In a spreadsheet: =(44-90)/90*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 48.8889% of the old one: for every 100 at the start there are now 48.8889, so 51.1111 out of every 100 have gone.

Sales: a price cut from $90 to $44 is a 51.1111% discount.

Why the change back is different

A 51.1111% fall followed by a 51.1111% rise does not bring you back to 90: it gives 66.4889. The second percentage is taken of 44, not of 90, so to undo this change you need 104.5455% instead.
