How to work it out

  1. Difference: 56 − 73 = -17
  2. Divide by the starting value: -17 ÷ 73 = -0.232877
  3. Multiply by 100: -23.2877%
  4. Check: Work forwards from the start: 73 × (1 − 0.232877) = 73 × 0.767123 = 56.

In a spreadsheet: =(56-73)/73*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 76.7123% of the old one: for every 100 at the start there are now 76.7123, so 23.2877 out of every 100 have gone.

Sales: a price cut from $73 to $56 is a 23.2877% discount.

Why the change back is different

A 23.2877% fall followed by a 23.2877% rise does not bring you back to 73: it gives 69.0411. The second percentage is taken of 56, not of 73, so to undo this change you need 30.3571% instead.
