How to work it out

  1. Difference: 8 − 54 = -46
  2. Divide by the starting value: -46 ÷ 54 = -0.851852
  3. Multiply by 100: -85.1852%
  4. Check: Work forwards from the start: 54 × (1 − 0.851852) = 54 × 0.148148 = 8.

In a spreadsheet: =(8-54)/54*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 14.8148% of the old one: for every 100 at the start there are now 14.8148, so 85.1852 out of every 100 have gone.

Sales: a price cut from $54 to $8 is a 85.1852% discount.

Why the change back is different

A 85.1852% fall followed by a 85.1852% rise does not bring you back to 54: it gives 14.8148. The second percentage is taken of 8, not of 54, so to undo this change you need 575% instead.
