How to work it out

  1. Difference: 14 − 15 = -1
  2. Divide by the starting value: -1 ÷ 15 = -0.066667
  3. Multiply by 100: -6.6667%
  4. Check: Work forwards from the start: 15 × (1 − 0.066667) = 15 × 0.933333 = 14.

In a spreadsheet: =(14-15)/15*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 93.3333% of the old one: for every 100 at the start there are now 93.3333, so 6.6667 out of every 100 have gone.

Sales: a price cut from $15 to $14 is a 6.6667% discount.

Why the change back is different

A 6.6667% fall followed by a 6.6667% rise does not bring you back to 15: it gives 14.9333. The second percentage is taken of 14, not of 15, so to undo this change you need 7.1429% instead.
