How to work it out

  1. Difference: 11 − 28 = -17
  2. Divide by the starting value: -17 ÷ 28 = -0.607143
  3. Multiply by 100: -60.7143%
  4. Check: Work forwards from the start: 28 × (1 − 0.607143) = 28 × 0.392857 = 11.

In a spreadsheet: =(11-28)/28*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 39.2857% of the old one: for every 100 at the start there are now 39.2857, so 60.7143 out of every 100 have gone.

Sales: a price cut from $28 to $11 is a 60.7143% discount.

Why the change back is different

A 60.7143% fall followed by a 60.7143% rise does not bring you back to 28: it gives 17.6786. The second percentage is taken of 11, not of 28, so to undo this change you need 154.5455% instead.
