How to work it out

  1. Difference: 16 − 49 = -33
  2. Divide by the starting value: -33 ÷ 49 = -0.673469
  3. Multiply by 100: -67.3469%
  4. Check: Work forwards from the start: 49 × (1 − 0.673469) = 49 × 0.326531 = 16.

In a spreadsheet: =(16-49)/49*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 32.6531% of the old one: for every 100 at the start there are now 32.6531, so 67.3469 out of every 100 have gone.

Sales: a price cut from $49 to $16 is a 67.3469% discount.

Why the change back is different

A 67.3469% fall followed by a 67.3469% rise does not bring you back to 49: it gives 26.7755. The second percentage is taken of 16, not of 49, so to undo this change you need 206.25% instead.
