How to work it out

  1. Difference: 15 − 47 = -32
  2. Divide by the starting value: -32 ÷ 47 = -0.680851
  3. Multiply by 100: -68.0851%
  4. Check: Work forwards from the start: 47 × (1 − 0.680851) = 47 × 0.319149 = 15.

In a spreadsheet: =(15-47)/47*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 31.9149% of the old one: for every 100 at the start there are now 31.9149, so 68.0851 out of every 100 have gone.

Sales: a price cut from $47 to $15 is a 68.0851% discount.

Why the change back is different

A 68.0851% fall followed by a 68.0851% rise does not bring you back to 47: it gives 25.2128. The second percentage is taken of 15, not of 47, so to undo this change you need 213.3333% instead.
