How to work it out

  1. Difference: 10 − 13 = -3
  2. Divide by the starting value: -3 ÷ 13 = -0.230769
  3. Multiply by 100: -23.0769%
  4. Check: Work forwards from the start: 13 × (1 − 0.230769) = 13 × 0.769231 = 10.

In a spreadsheet: =(10-13)/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 76.9231% of the old one: for every 100 at the start there are now 76.9231, so 23.0769 out of every 100 have gone.

Sales: a price cut from $13 to $10 is a 23.0769% discount.

Why the change back is different

A 23.0769% fall followed by a 23.0769% rise does not bring you back to 13: it gives 12.3077. The second percentage is taken of 10, not of 13, so to undo this change you need 30% instead.
