How to work it out

  1. Difference: 43 − 55 = -12
  2. Divide by the starting value: -12 ÷ 55 = -0.218182
  3. Multiply by 100: -21.8182%
  4. Check: Work forwards from the start: 55 × (1 − 0.218182) = 55 × 0.781818 = 43.

In a spreadsheet: =(43-55)/55*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 78.1818% of the old one: for every 100 at the start there are now 78.1818, so 21.8182 out of every 100 have gone.

Sales: a price cut from $55 to $43 is a 21.8182% discount.

Why the change back is different

A 21.8182% fall followed by a 21.8182% rise does not bring you back to 55: it gives 52.3818. The second percentage is taken of 43, not of 55, so to undo this change you need 27.907% instead.
