How to work it out

  1. Difference: 43 − 49 = -6
  2. Divide by the starting value: -6 ÷ 49 = -0.122449
  3. Multiply by 100: -12.2449%
  4. Check: Work forwards from the start: 49 × (1 − 0.122449) = 49 × 0.877551 = 43.

In a spreadsheet: =(43-49)/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 87.7551% of the old one: for every 100 at the start there are now 87.7551, so 12.2449 out of every 100 have gone.

Sales: a price cut from $49 to $43 is a 12.2449% discount.

Why the change back is different

A 12.2449% fall followed by a 12.2449% rise does not bring you back to 49: it gives 48.2653. The second percentage is taken of 43, not of 49, so to undo this change you need 13.9535% instead.
