How to work it out

  1. Difference: 27 − 57 = -30
  2. Divide by the starting value: -30 ÷ 57 = -0.526316
  3. Multiply by 100: -52.6316%
  4. Check: Work forwards from the start: 57 × (1 − 0.526316) = 57 × 0.473684 = 27.

In a spreadsheet: =(27-57)/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 47.3684% of the old one: for every 100 at the start there are now 47.3684, so 52.6316 out of every 100 have gone.

Sales: a price cut from $57 to $27 is a 52.6316% discount.

Why the change back is different

A 52.6316% fall followed by a 52.6316% rise does not bring you back to 57: it gives 41.2105. The second percentage is taken of 27, not of 57, so to undo this change you need 111.1111% instead.
