How to work it out

  1. Difference: 28 − 38 = -10
  2. Divide by the starting value: -10 ÷ 38 = -0.263158
  3. Multiply by 100: -26.3158%
  4. Check: Work forwards from the start: 38 × (1 − 0.263158) = 38 × 0.736842 = 28.

In a spreadsheet: =(28-38)/38*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 73.6842% of the old one: for every 100 at the start there are now 73.6842, so 26.3158 out of every 100 have gone.

Sales: a price cut from $38 to $28 is a 26.3158% discount.

Why the change back is different

A 26.3158% fall followed by a 26.3158% rise does not bring you back to 38: it gives 35.3684. The second percentage is taken of 28, not of 38, so to undo this change you need 35.7143% instead.
