How to work it out

  1. Difference: 65 − 43 = 22
  2. Divide by the starting value: 22 ÷ 43 = 0.511628
  3. Multiply by 100: 51.1628%
  4. Check: Work forwards from the start: 43 × (1 + 0.511628) = 43 × 1.511628 = 65.

In a spreadsheet: =(65-43)/43*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 1.5116 times the old one: for every 100 at the start there are now 151.1628.

Prices: an item whose price rises from $43 to $65 has gone up by 51.1628%.

Why the change back is different

A 51.1628% rise followed by a 51.1628% fall does not bring you back to 43: it gives 31.7442. The second percentage is taken of 65, not of 43, so to undo this change you need 33.8462% instead.
