How to work it out

  1. Difference: 24 − 29 = -5
  2. Divide by the starting value: -5 ÷ 29 = -0.172414
  3. Multiply by 100: -17.2414%
  4. Check: Work forwards from the start: 29 × (1 − 0.172414) = 29 × 0.827586 = 24.

In a spreadsheet: =(24-29)/29*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 82.7586% of the old one: for every 100 at the start there are now 82.7586, so 17.2414 out of every 100 have gone.

Sales: a price cut from $29 to $24 is a 17.2414% discount.

Why the change back is different

A 17.2414% fall followed by a 17.2414% rise does not bring you back to 29: it gives 28.1379. The second percentage is taken of 24, not of 29, so to undo this change you need 20.8333% instead.
