How to work it out

  1. Difference: 11 − 50 = -39
  2. Divide by the starting value: -39 ÷ 50 = -0.78
  3. Multiply by 100: -78%
  4. Check: Work forwards from the start: 50 × (1 − 0.78) = 50 × 0.22 = 11.

In a spreadsheet: =(11-50)/50*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 22% of the old one: for every 100 at the start there are now 22, so 78 out of every 100 have gone.

Sales: a price cut from $50 to $11 is a 78% discount.

Why the change back is different

A 78% fall followed by a 78% rise does not bring you back to 50: it gives 19.58. The second percentage is taken of 11, not of 50, so to undo this change you need 354.5455% instead.
