How to work it out

  1. Difference: 12 − 82 = -70
  2. Divide by the starting value: -70 ÷ 82 = -0.853659
  3. Multiply by 100: -85.3659%
  4. Check: Work forwards from the start: 82 × (1 − 0.853659) = 82 × 0.146341 = 12.

In a spreadsheet: =(12-82)/82*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 14.6341% of the old one: for every 100 at the start there are now 14.6341, so 85.3659 out of every 100 have gone.

Sales: a price cut from $82 to $12 is a 85.3659% discount.

Why the change back is different

A 85.3659% fall followed by a 85.3659% rise does not bring you back to 82: it gives 22.2439. The second percentage is taken of 12, not of 82, so to undo this change you need 583.3333% instead.
