How to work it out

  1. Difference: 51 − 73 = -22
  2. Divide by the starting value: -22 ÷ 73 = -0.30137
  3. Multiply by 100: -30.137%
  4. Check: Work forwards from the start: 73 × (1 − 0.30137) = 73 × 0.69863 = 51.

In a spreadsheet: =(51-73)/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 69.863% of the old one: for every 100 at the start there are now 69.863, so 30.137 out of every 100 have gone.

Sales: a price cut from $73 to $51 is a 30.137% discount.

Why the change back is different

A 30.137% fall followed by a 30.137% rise does not bring you back to 73: it gives 66.3699. The second percentage is taken of 51, not of 73, so to undo this change you need 43.1373% instead.
