How to work it out

  1. Difference: 10 − 73 = -63
  2. Divide by the starting value: -63 ÷ 73 = -0.863014
  3. Multiply by 100: -86.3014%
  4. Check: Work forwards from the start: 73 × (1 − 0.863014) = 73 × 0.136986 = 10.

In a spreadsheet: =(10-73)/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 13.6986% of the old one: for every 100 at the start there are now 13.6986, so 86.3014 out of every 100 have gone.

Sales: a price cut from $73 to $10 is a 86.3014% discount.

Why the change back is different

A 86.3014% fall followed by a 86.3014% rise does not bring you back to 73: it gives 18.6301. The second percentage is taken of 10, not of 73, so to undo this change you need 630% instead.
