How to work it out

  1. Difference: 56 − 57 = -1
  2. Divide by the starting value: -1 ÷ 57 = -0.017544
  3. Multiply by 100: -1.7544%
  4. Check: Work forwards from the start: 57 × (1 − 0.017544) = 57 × 0.982456 = 56.

In a spreadsheet: =(56-57)/57*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 98.2456% of the old one: for every 100 at the start there are now 98.2456, so 1.7544 out of every 100 have gone.

Sales: a price cut from $57 to $56 is a 1.7544% discount.

Why the change back is different

A 1.7544% fall followed by a 1.7544% rise does not bring you back to 57: it gives 56.9825. The second percentage is taken of 56, not of 57, so to undo this change you need 1.7857% instead.
