How to work it out

  1. Difference: 57 − 73 = -16
  2. Divide by the starting value: -16 ÷ 73 = -0.219178
  3. Multiply by 100: -21.9178%
  4. Check: Work forwards from the start: 73 × (1 − 0.219178) = 73 × 0.780822 = 57.

In a spreadsheet: =(57-73)/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 78.0822% of the old one: for every 100 at the start there are now 78.0822, so 21.9178 out of every 100 have gone.

Sales: a price cut from $73 to $57 is a 21.9178% discount.

Why the change back is different

A 21.9178% fall followed by a 21.9178% rise does not bring you back to 73: it gives 69.4932. The second percentage is taken of 57, not of 73, so to undo this change you need 28.0702% instead.
