How to work it out

  1. Difference: 12 − 64 = -52
  2. Divide by the starting value: -52 ÷ 64 = -0.8125
  3. Multiply by 100: -81.25%
  4. Check: Work forwards from the start: 64 × (1 − 0.8125) = 64 × 0.1875 = 12.

In a spreadsheet: =(12-64)/64*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 18.75% of the old one: for every 100 at the start there are now 18.75, so 81.25 out of every 100 have gone.

Sales: a price cut from $64 to $12 is a 81.25% discount.

Why the change back is different

A 81.25% fall followed by a 81.25% rise does not bring you back to 64: it gives 21.75. The second percentage is taken of 12, not of 64, so to undo this change you need 433.3333% instead.
