How to work it out

  1. Difference: 15 − 69 = -54
  2. Divide by the starting value: -54 ÷ 69 = -0.782609
  3. Multiply by 100: -78.2609%
  4. Check: Work forwards from the start: 69 × (1 − 0.782609) = 69 × 0.217391 = 15.

In a spreadsheet: =(15-69)/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 21.7391% of the old one: for every 100 at the start there are now 21.7391, so 78.2609 out of every 100 have gone.

Sales: a price cut from $69 to $15 is a 78.2609% discount.

Why the change back is different

A 78.2609% fall followed by a 78.2609% rise does not bring you back to 69: it gives 26.7391. The second percentage is taken of 15, not of 69, so to undo this change you need 360% instead.
