How to work it out

  1. Difference: 6 − 9 = -3
  2. Divide by the starting value: -3 ÷ 9 = -0.333333
  3. Multiply by 100: -33.3333%
  4. Check: Work forwards from the start: 9 × (1 − 0.333333) = 9 × 0.666667 = 6.

In a spreadsheet: =(6-9)/9*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 66.6667% of the old one: for every 100 at the start there are now 66.6667, so 33.3333 out of every 100 have gone.

Sales: a price cut from $9 to $6 is a 33.3333% discount.

Why the change back is different

A 33.3333% fall followed by a 33.3333% rise does not bring you back to 9: it gives 8. The second percentage is taken of 6, not of 9, so to undo this change you need 50% instead.
