How to work it out

  1. Difference: 43 − 84 = -41
  2. Divide by the starting value: -41 ÷ 84 = -0.488095
  3. Multiply by 100: -48.8095%
  4. Check: Work forwards from the start: 84 × (1 − 0.488095) = 84 × 0.511905 = 43.

In a spreadsheet: =(43-84)/84*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 51.1905% of the old one: for every 100 at the start there are now 51.1905, so 48.8095 out of every 100 have gone.

Sales: a price cut from $84 to $43 is a 48.8095% discount.

Why the change back is different

A 48.8095% fall followed by a 48.8095% rise does not bring you back to 84: it gives 63.9881. The second percentage is taken of 43, not of 84, so to undo this change you need 95.3488% instead.
