How to work it out

  1. Difference: 61 − 77 = -16
  2. Divide by the starting value: -16 ÷ 77 = -0.207792
  3. Multiply by 100: -20.7792%
  4. Check: Work forwards from the start: 77 × (1 − 0.207792) = 77 × 0.792208 = 61.

In a spreadsheet: =(61-77)/77*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 79.2208% of the old one: for every 100 at the start there are now 79.2208, so 20.7792 out of every 100 have gone.

Sales: a price cut from $77 to $61 is a 20.7792% discount.

Why the change back is different

A 20.7792% fall followed by a 20.7792% rise does not bring you back to 77: it gives 73.6753. The second percentage is taken of 61, not of 77, so to undo this change you need 26.2295% instead.
