How to work it out

  1. Difference: 12 − 17 = -5
  2. Divide by the starting value: -5 ÷ 17 = -0.294118
  3. Multiply by 100: -29.4118%
  4. Check: Work forwards from the start: 17 × (1 − 0.294118) = 17 × 0.705882 = 12.

In a spreadsheet: =(12-17)/17*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 70.5882% of the old one: for every 100 at the start there are now 70.5882, so 29.4118 out of every 100 have gone.

Sales: a price cut from $17 to $12 is a 29.4118% discount.

Why the change back is different

A 29.4118% fall followed by a 29.4118% rise does not bring you back to 17: it gives 15.5294. The second percentage is taken of 12, not of 17, so to undo this change you need 41.6667% instead.
