How to work it out

  1. Difference: 38 − 55 = -17
  2. Divide by the starting value: -17 ÷ 55 = -0.309091
  3. Multiply by 100: -30.9091%
  4. Check: Work forwards from the start: 55 × (1 − 0.309091) = 55 × 0.690909 = 38.

In a spreadsheet: =(38-55)/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 69.0909% of the old one: for every 100 at the start there are now 69.0909, so 30.9091 out of every 100 have gone.

Sales: a price cut from $55 to $38 is a 30.9091% discount.

Why the change back is different

A 30.9091% fall followed by a 30.9091% rise does not bring you back to 55: it gives 49.7455. The second percentage is taken of 38, not of 55, so to undo this change you need 44.7368% instead.
