How to work it out

  1. Difference: 75 − 78 = -3
  2. Divide by the starting value: -3 ÷ 78 = -0.038462
  3. Multiply by 100: -3.8462%
  4. Check: Work forwards from the start: 78 × (1 − 0.038462) = 78 × 0.961538 = 75.

In a spreadsheet: =(75-78)/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 96.1538% of the old one: for every 100 at the start there are now 96.1538, so 3.8462 out of every 100 have gone.

Sales: a price cut from $78 to $75 is a 3.8462% discount.

Why the change back is different

A 3.8462% fall followed by a 3.8462% rise does not bring you back to 78: it gives 77.8846. The second percentage is taken of 75, not of 78, so to undo this change you need 4% instead.
