How to work it out

  1. Difference: 34 − 47 = -13
  2. Divide by the starting value: -13 ÷ 47 = -0.276596
  3. Multiply by 100: -27.6596%
  4. Check: Work forwards from the start: 47 × (1 − 0.276596) = 47 × 0.723404 = 34.

In a spreadsheet: =(34-47)/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 72.3404% of the old one: for every 100 at the start there are now 72.3404, so 27.6596 out of every 100 have gone.

Sales: a price cut from $47 to $34 is a 27.6596% discount.

Why the change back is different

A 27.6596% fall followed by a 27.6596% rise does not bring you back to 47: it gives 43.4043. The second percentage is taken of 34, not of 47, so to undo this change you need 38.2353% instead.
