How to work it out

  1. Difference: 20 − 36 = -16
  2. Divide by the starting value: -16 ÷ 36 = -0.444444
  3. Multiply by 100: -44.4444%
  4. Check: Work forwards from the start: 36 × (1 − 0.444444) = 36 × 0.555556 = 20.

In a spreadsheet: =(20-36)/36*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 55.5556% of the old one: for every 100 at the start there are now 55.5556, so 44.4444 out of every 100 have gone.

Sales: a price cut from $36 to $20 is a 44.4444% discount.

Why the change back is different

A 44.4444% fall followed by a 44.4444% rise does not bring you back to 36: it gives 28.8889. The second percentage is taken of 20, not of 36, so to undo this change you need 80% instead.
