How to work it out

  1. Difference: 31 − 56 = -25
  2. Divide by the starting value: -25 ÷ 56 = -0.446429
  3. Multiply by 100: -44.6429%
  4. Check: Work forwards from the start: 56 × (1 − 0.446429) = 56 × 0.553571 = 31.

In a spreadsheet: =(31-56)/56*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 55.3571% of the old one: for every 100 at the start there are now 55.3571, so 44.6429 out of every 100 have gone.

Sales: a price cut from $56 to $31 is a 44.6429% discount.

Why the change back is different

A 44.6429% fall followed by a 44.6429% rise does not bring you back to 56: it gives 44.8393. The second percentage is taken of 31, not of 56, so to undo this change you need 80.6452% instead.
