How to work it out

  1. Difference: 12 − 83 = -71
  2. Divide by the starting value: -71 ÷ 83 = -0.855422
  3. Multiply by 100: -85.5422%
  4. Check: Work forwards from the start: 83 × (1 − 0.855422) = 83 × 0.144578 = 12.

In a spreadsheet: =(12-83)/83*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 14.4578% of the old one: for every 100 at the start there are now 14.4578, so 85.5422 out of every 100 have gone.

Sales: a price cut from $83 to $12 is a 85.5422% discount.

Why the change back is different

A 85.5422% fall followed by a 85.5422% rise does not bring you back to 83: it gives 22.2651. The second percentage is taken of 12, not of 83, so to undo this change you need 591.6667% instead.
