How to work it out

  1. Difference: 55 − 57 = -2
  2. Divide by the starting value: -2 ÷ 57 = -0.035088
  3. Multiply by 100: -3.5088%
  4. Check: Work forwards from the start: 57 × (1 − 0.035088) = 57 × 0.964912 = 55.

In a spreadsheet: =(55-57)/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 96.4912% of the old one: for every 100 at the start there are now 96.4912, so 3.5088 out of every 100 have gone.

Sales: a price cut from $57 to $55 is a 3.5088% discount.

Why the change back is different

A 3.5088% fall followed by a 3.5088% rise does not bring you back to 57: it gives 56.9298. The second percentage is taken of 55, not of 57, so to undo this change you need 3.6364% instead.
