How to work it out

  1. Difference: 6 − 13 = -7
  2. Divide by the starting value: -7 ÷ 13 = -0.538462
  3. Multiply by 100: -53.8462%
  4. Check: Work forwards from the start: 13 × (1 − 0.538462) = 13 × 0.461538 = 6.

In a spreadsheet: =(6-13)/13*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 46.1538% of the old one: for every 100 at the start there are now 46.1538, so 53.8462 out of every 100 have gone.

Sales: a price cut from $13 to $6 is a 53.8462% discount.

Why the change back is different

A 53.8462% fall followed by a 53.8462% rise does not bring you back to 13: it gives 9.2308. The second percentage is taken of 6, not of 13, so to undo this change you need 116.6667% instead.
