How to work it out

  1. Difference: 5 − 39 = -34
  2. Divide by the starting value: -34 ÷ 39 = -0.871795
  3. Multiply by 100: -87.1795%
  4. Check: Work forwards from the start: 39 × (1 − 0.871795) = 39 × 0.128205 = 5.

In a spreadsheet: =(5-39)/39*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 12.8205% of the old one: for every 100 at the start there are now 12.8205, so 87.1795 out of every 100 have gone.

Sales: a price cut from $39 to $5 is a 87.1795% discount.

Why the change back is different

A 87.1795% fall followed by a 87.1795% rise does not bring you back to 39: it gives 9.359. The second percentage is taken of 5, not of 39, so to undo this change you need 680% instead.
