How to work it out

  1. Difference: 16 − 55 = -39
  2. Divide by the starting value: -39 ÷ 55 = -0.709091
  3. Multiply by 100: -70.9091%
  4. Check: Work forwards from the start: 55 × (1 − 0.709091) = 55 × 0.290909 = 16.

In a spreadsheet: =(16-55)/55*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 29.0909% of the old one: for every 100 at the start there are now 29.0909, so 70.9091 out of every 100 have gone.

Sales: a price cut from $55 to $16 is a 70.9091% discount.

Why the change back is different

A 70.9091% fall followed by a 70.9091% rise does not bring you back to 55: it gives 27.3455. The second percentage is taken of 16, not of 55, so to undo this change you need 243.75% instead.
