How to work it out

  1. Difference: 65 − 78 = -13
  2. Divide by the starting value: -13 ÷ 78 = -0.166667
  3. Multiply by 100: -16.6667%
  4. Check: Work forwards from the start: 78 × (1 − 0.166667) = 78 × 0.833333 = 65.

In a spreadsheet: =(65-78)/78*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 83.3333% of the old one: for every 100 at the start there are now 83.3333, so 16.6667 out of every 100 have gone.

Sales: a price cut from $78 to $65 is a 16.6667% discount.

Why the change back is different

A 16.6667% fall followed by a 16.6667% rise does not bring you back to 78: it gives 75.8333. The second percentage is taken of 65, not of 78, so to undo this change you need 20% instead.
