How to work it out

  1. Difference: 38 − 51 = -13
  2. Divide by the starting value: -13 ÷ 51 = -0.254902
  3. Multiply by 100: -25.4902%
  4. Check: Work forwards from the start: 51 × (1 − 0.254902) = 51 × 0.745098 = 38.

In a spreadsheet: =(38-51)/51*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 74.5098% of the old one: for every 100 at the start there are now 74.5098, so 25.4902 out of every 100 have gone.

Sales: a price cut from $51 to $38 is a 25.4902% discount.

Why the change back is different

A 25.4902% fall followed by a 25.4902% rise does not bring you back to 51: it gives 47.6863. The second percentage is taken of 38, not of 51, so to undo this change you need 34.2105% instead.
