How to work it out

  1. Difference: 23 − 68 = -45
  2. Divide by the starting value: -45 ÷ 68 = -0.661765
  3. Multiply by 100: -66.1765%
  4. Check: Work forwards from the start: 68 × (1 − 0.661765) = 68 × 0.338235 = 23.

In a spreadsheet: =(23-68)/68*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 33.8235% of the old one: for every 100 at the start there are now 33.8235, so 66.1765 out of every 100 have gone.

Sales: a price cut from $68 to $23 is a 66.1765% discount.

Why the change back is different

A 66.1765% fall followed by a 66.1765% rise does not bring you back to 68: it gives 38.2206. The second percentage is taken of 23, not of 68, so to undo this change you need 195.6522% instead.
