How to work it out

  1. Difference: 51 − 57 = -6
  2. Divide by the starting value: -6 ÷ 57 = -0.105263
  3. Multiply by 100: -10.5263%
  4. Check: Work forwards from the start: 57 × (1 − 0.105263) = 57 × 0.894737 = 51.

In a spreadsheet: =(51-57)/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 89.4737% of the old one: for every 100 at the start there are now 89.4737, so 10.5263 out of every 100 have gone.

Sales: a price cut from $57 to $51 is a 10.5263% discount.

Why the change back is different

A 10.5263% fall followed by a 10.5263% rise does not bring you back to 57: it gives 56.3684. The second percentage is taken of 51, not of 57, so to undo this change you need 11.7647% instead.
