How to work it out

  1. Difference: 50 − 61 = -11
  2. Divide by the starting value: -11 ÷ 61 = -0.180328
  3. Multiply by 100: -18.0328%
  4. Check: Work forwards from the start: 61 × (1 − 0.180328) = 61 × 0.819672 = 50.

In a spreadsheet: =(50-61)/61*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 81.9672% of the old one: for every 100 at the start there are now 81.9672, so 18.0328 out of every 100 have gone.

Sales: a price cut from $61 to $50 is a 18.0328% discount.

Why the change back is different

A 18.0328% fall followed by a 18.0328% rise does not bring you back to 61: it gives 59.0164. The second percentage is taken of 50, not of 61, so to undo this change you need 22% instead.
