How to work it out

  1. Difference: 65 − 42 = 23
  2. Divide by the starting value: 23 ÷ 42 = 0.547619
  3. Multiply by 100: 54.7619%
  4. Check: Work forwards from the start: 42 × (1 + 0.547619) = 42 × 1.547619 = 65.

In a spreadsheet: =(65-42)/42*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 1.5476 times the old one: for every 100 at the start there are now 154.7619.

Prices: an item whose price rises from $42 to $65 has gone up by 54.7619%.

Why the change back is different

A 54.7619% rise followed by a 54.7619% fall does not bring you back to 42: it gives 29.4048. The second percentage is taken of 65, not of 42, so to undo this change you need 35.3846% instead.
