How to work it out

  1. Difference: 78 − 95 = -17
  2. Divide by the starting value: -17 ÷ 95 = -0.178947
  3. Multiply by 100: -17.8947%
  4. Check: Work forwards from the start: 95 × (1 − 0.178947) = 95 × 0.821053 = 78.

In a spreadsheet: =(78-95)/95*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 82.1053% of the old one: for every 100 at the start there are now 82.1053, so 17.8947 out of every 100 have gone.

Sales: a price cut from $95 to $78 is a 17.8947% discount.

Why the change back is different

A 17.8947% fall followed by a 17.8947% rise does not bring you back to 95: it gives 91.9579. The second percentage is taken of 78, not of 95, so to undo this change you need 21.7949% instead.
