How to work it out

  1. Difference: 17 − 24 = -7
  2. Divide by the starting value: -7 ÷ 24 = -0.291667
  3. Multiply by 100: -29.1667%
  4. Check: Work forwards from the start: 24 × (1 − 0.291667) = 24 × 0.708333 = 17.

In a spreadsheet: =(17-24)/24*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 70.8333% of the old one: for every 100 at the start there are now 70.8333, so 29.1667 out of every 100 have gone.

Sales: a price cut from $24 to $17 is a 29.1667% discount.

Why the change back is different

A 29.1667% fall followed by a 29.1667% rise does not bring you back to 24: it gives 21.9583. The second percentage is taken of 17, not of 24, so to undo this change you need 41.1765% instead.
