How to work it out

  1. Difference: 4 − 47 = -43
  2. Divide by the starting value: -43 ÷ 47 = -0.914894
  3. Multiply by 100: -91.4894%
  4. Check: Work forwards from the start: 47 × (1 − 0.914894) = 47 × 0.085106 = 4.

In a spreadsheet: =(4-47)/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 8.5106% of the old one: for every 100 at the start there are now 8.5106, so 91.4894 out of every 100 have gone.

Sales: a price cut from $47 to $4 is a 91.4894% discount.

Why the change back is different

A 91.4894% fall followed by a 91.4894% rise does not bring you back to 47: it gives 7.6596. The second percentage is taken of 4, not of 47, so to undo this change you need 1,075% instead.
