How to work it out

  1. Difference: 11 − 61 = -50
  2. Divide by the starting value: -50 ÷ 61 = -0.819672
  3. Multiply by 100: -81.9672%
  4. Check: Work forwards from the start: 61 × (1 − 0.819672) = 61 × 0.180328 = 11.

In a spreadsheet: =(11-61)/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 18.0328% of the old one: for every 100 at the start there are now 18.0328, so 81.9672 out of every 100 have gone.

Sales: a price cut from $61 to $11 is a 81.9672% discount.

Why the change back is different

A 81.9672% fall followed by a 81.9672% rise does not bring you back to 61: it gives 20.0164. The second percentage is taken of 11, not of 61, so to undo this change you need 454.5455% instead.
