How to work it out

  1. Difference: 27 − 36 = -9
  2. Divide by the starting value: -9 ÷ 36 = -0.25
  3. Multiply by 100: -25%
  4. Check: Work forwards from the start: 36 × (1 − 0.25) = 36 × 0.75 = 27.

In a spreadsheet: =(27-36)/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 75% of the old one: for every 100 at the start there are now 75, so 25 out of every 100 have gone.

Sales: a price cut from $36 to $27 is a 25% discount.

Why the change back is different

A 25% fall followed by a 25% rise does not bring you back to 36: it gives 33.75. The second percentage is taken of 27, not of 36, so to undo this change you need 33.3333% instead.
