How to work it out

  1. Difference: 24 − 27 = -3
  2. Divide by the starting value: -3 ÷ 27 = -0.111111
  3. Multiply by 100: -11.1111%
  4. Check: Work forwards from the start: 27 × (1 − 0.111111) = 27 × 0.888889 = 24.

In a spreadsheet: =(24-27)/27*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 88.8889% of the old one: for every 100 at the start there are now 88.8889, so 11.1111 out of every 100 have gone.

Sales: a price cut from $27 to $24 is a 11.1111% discount.

Why the change back is different

A 11.1111% fall followed by a 11.1111% rise does not bring you back to 27: it gives 26.6667. The second percentage is taken of 24, not of 27, so to undo this change you need 12.5% instead.
