How to work it out

  1. Difference: 19 − 36 = -17
  2. Divide by the starting value: -17 ÷ 36 = -0.472222
  3. Multiply by 100: -47.2222%
  4. Check: Work forwards from the start: 36 × (1 − 0.472222) = 36 × 0.527778 = 19.

In a spreadsheet: =(19-36)/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 52.7778% of the old one: for every 100 at the start there are now 52.7778, so 47.2222 out of every 100 have gone.

Sales: a price cut from $36 to $19 is a 47.2222% discount.

Why the change back is different

A 47.2222% fall followed by a 47.2222% rise does not bring you back to 36: it gives 27.9722. The second percentage is taken of 19, not of 36, so to undo this change you need 89.4737% instead.
