How to work it out

  1. Difference: 43 − 61 = -18
  2. Divide by the starting value: -18 ÷ 61 = -0.295082
  3. Multiply by 100: -29.5082%
  4. Check: Work forwards from the start: 61 × (1 − 0.295082) = 61 × 0.704918 = 43.

In a spreadsheet: =(43-61)/61*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 70.4918% of the old one: for every 100 at the start there are now 70.4918, so 29.5082 out of every 100 have gone.

Sales: a price cut from $61 to $43 is a 29.5082% discount.

Why the change back is different

A 29.5082% fall followed by a 29.5082% rise does not bring you back to 61: it gives 55.6885. The second percentage is taken of 43, not of 61, so to undo this change you need 41.8605% instead.
