How to work it out

  1. Difference: 46 − 78 = -32
  2. Divide by the starting value: -32 ÷ 78 = -0.410256
  3. Multiply by 100: -41.0256%
  4. Check: Work forwards from the start: 78 × (1 − 0.410256) = 78 × 0.589744 = 46.

In a spreadsheet: =(46-78)/78*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 58.9744% of the old one: for every 100 at the start there are now 58.9744, so 41.0256 out of every 100 have gone.

Sales: a price cut from $78 to $46 is a 41.0256% discount.

Why the change back is different

A 41.0256% fall followed by a 41.0256% rise does not bring you back to 78: it gives 64.8718. The second percentage is taken of 46, not of 78, so to undo this change you need 69.5652% instead.
