How to work it out

  1. Difference: 36 − 49 = -13
  2. Divide by the starting value: -13 ÷ 49 = -0.265306
  3. Multiply by 100: -26.5306%
  4. Check: Work forwards from the start: 49 × (1 − 0.265306) = 49 × 0.734694 = 36.

In a spreadsheet: =(36-49)/49*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 73.4694% of the old one: for every 100 at the start there are now 73.4694, so 26.5306 out of every 100 have gone.

Sales: a price cut from $49 to $36 is a 26.5306% discount.

Why the change back is different

A 26.5306% fall followed by a 26.5306% rise does not bring you back to 49: it gives 45.551. The second percentage is taken of 36, not of 49, so to undo this change you need 36.1111% instead.
