How to work it out

  1. Difference: 12 − 93 = -81
  2. Divide by the starting value: -81 ÷ 93 = -0.870968
  3. Multiply by 100: -87.0968%
  4. Check: Work forwards from the start: 93 × (1 − 0.870968) = 93 × 0.129032 = 12.

In a spreadsheet: =(12-93)/93*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 12.9032% of the old one: for every 100 at the start there are now 12.9032, so 87.0968 out of every 100 have gone.

Sales: a price cut from $93 to $12 is a 87.0968% discount.

Why the change back is different

A 87.0968% fall followed by a 87.0968% rise does not bring you back to 93: it gives 22.4516. The second percentage is taken of 12, not of 93, so to undo this change you need 675% instead.
