How to work it out

  1. Difference: 43 − 77 = -34
  2. Divide by the starting value: -34 ÷ 77 = -0.441558
  3. Multiply by 100: -44.1558%
  4. Check: Work forwards from the start: 77 × (1 − 0.441558) = 77 × 0.558442 = 43.

In a spreadsheet: =(43-77)/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 55.8442% of the old one: for every 100 at the start there are now 55.8442, so 44.1558 out of every 100 have gone.

Sales: a price cut from $77 to $43 is a 44.1558% discount.

Why the change back is different

A 44.1558% fall followed by a 44.1558% rise does not bring you back to 77: it gives 61.987. The second percentage is taken of 43, not of 77, so to undo this change you need 79.0698% instead.
