How to work it out

  1. Difference: 7 − 69 = -62
  2. Divide by the starting value: -62 ÷ 69 = -0.898551
  3. Multiply by 100: -89.8551%
  4. Check: Work forwards from the start: 69 × (1 − 0.898551) = 69 × 0.101449 = 7.

In a spreadsheet: =(7-69)/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 10.1449% of the old one: for every 100 at the start there are now 10.1449, so 89.8551 out of every 100 have gone.

Sales: a price cut from $69 to $7 is a 89.8551% discount.

Why the change back is different

A 89.8551% fall followed by a 89.8551% rise does not bring you back to 69: it gives 13.2899. The second percentage is taken of 7, not of 69, so to undo this change you need 885.7143% instead.
