How to work it out

  1. Difference: 66 − 69 = -3
  2. Divide by the starting value: -3 ÷ 69 = -0.043478
  3. Multiply by 100: -4.3478%
  4. Check: Work forwards from the start: 69 × (1 − 0.043478) = 69 × 0.956522 = 66.

In a spreadsheet: =(66-69)/69*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 95.6522% of the old one: for every 100 at the start there are now 95.6522, so 4.3478 out of every 100 have gone.

Sales: a price cut from $69 to $66 is a 4.3478% discount.

Why the change back is different

A 4.3478% fall followed by a 4.3478% rise does not bring you back to 69: it gives 68.8696. The second percentage is taken of 66, not of 69, so to undo this change you need 4.5455% instead.
