How to work it out

  1. Difference: 26 − 42 = -16
  2. Divide by the starting value: -16 ÷ 42 = -0.380952
  3. Multiply by 100: -38.0952%
  4. Check: Work forwards from the start: 42 × (1 − 0.380952) = 42 × 0.619048 = 26.

In a spreadsheet: =(26-42)/42*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 61.9048% of the old one: for every 100 at the start there are now 61.9048, so 38.0952 out of every 100 have gone.

Sales: a price cut from $42 to $26 is a 38.0952% discount.

Why the change back is different

A 38.0952% fall followed by a 38.0952% rise does not bring you back to 42: it gives 35.9048. The second percentage is taken of 26, not of 42, so to undo this change you need 61.5385% instead.
