How to work it out

  1. Difference: 55 − 56 = -1
  2. Divide by the starting value: -1 ÷ 56 = -0.017857
  3. Multiply by 100: -1.7857%
  4. Check: Work forwards from the start: 56 × (1 − 0.017857) = 56 × 0.982143 = 55.

In a spreadsheet: =(55-56)/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 98.2143% of the old one: for every 100 at the start there are now 98.2143, so 1.7857 out of every 100 have gone.

Sales: a price cut from $56 to $55 is a 1.7857% discount.

Why the change back is different

A 1.7857% fall followed by a 1.7857% rise does not bring you back to 56: it gives 55.9821. The second percentage is taken of 55, not of 56, so to undo this change you need 1.8182% instead.
