How to work it out

  1. Difference: 18 − 94 = -76
  2. Divide by the starting value: -76 ÷ 94 = -0.808511
  3. Multiply by 100: -80.8511%
  4. Check: Work forwards from the start: 94 × (1 − 0.808511) = 94 × 0.191489 = 18.

In a spreadsheet: =(18-94)/94*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 19.1489% of the old one: for every 100 at the start there are now 19.1489, so 80.8511 out of every 100 have gone.

Sales: a price cut from $94 to $18 is a 80.8511% discount.

Why the change back is different

A 80.8511% fall followed by a 80.8511% rise does not bring you back to 94: it gives 32.5532. The second percentage is taken of 18, not of 94, so to undo this change you need 422.2222% instead.
