How to work it out

  1. Difference: 13 − 36 = -23
  2. Divide by the starting value: -23 ÷ 36 = -0.638889
  3. Multiply by 100: -63.8889%
  4. Check: Work forwards from the start: 36 × (1 − 0.638889) = 36 × 0.361111 = 13.

In a spreadsheet: =(13-36)/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 36.1111% of the old one: for every 100 at the start there are now 36.1111, so 63.8889 out of every 100 have gone.

Sales: a price cut from $36 to $13 is a 63.8889% discount.

Why the change back is different

A 63.8889% fall followed by a 63.8889% rise does not bring you back to 36: it gives 21.3056. The second percentage is taken of 13, not of 36, so to undo this change you need 176.9231% instead.
