How to work it out

  1. Difference: 16 − 77 = -61
  2. Divide by the starting value: -61 ÷ 77 = -0.792208
  3. Multiply by 100: -79.2208%
  4. Check: Work forwards from the start: 77 × (1 − 0.792208) = 77 × 0.207792 = 16.

In a spreadsheet: =(16-77)/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 20.7792% of the old one: for every 100 at the start there are now 20.7792, so 79.2208 out of every 100 have gone.

Sales: a price cut from $77 to $16 is a 79.2208% discount.

Why the change back is different

A 79.2208% fall followed by a 79.2208% rise does not bring you back to 77: it gives 28.6753. The second percentage is taken of 16, not of 77, so to undo this change you need 381.25% instead.
