How to work it out

  1. Difference: 16 − 23 = -7
  2. Divide by the starting value: -7 ÷ 23 = -0.304348
  3. Multiply by 100: -30.4348%
  4. Check: Work forwards from the start: 23 × (1 − 0.304348) = 23 × 0.695652 = 16.

In a spreadsheet: =(16-23)/23*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 69.5652% of the old one: for every 100 at the start there are now 69.5652, so 30.4348 out of every 100 have gone.

Sales: a price cut from $23 to $16 is a 30.4348% discount.

Why the change back is different

A 30.4348% fall followed by a 30.4348% rise does not bring you back to 23: it gives 20.8696. The second percentage is taken of 16, not of 23, so to undo this change you need 43.75% instead.
