How to work it out

  1. Difference: 88 − 42 = 46
  2. Divide by the starting value: 46 ÷ 42 = 1.095238
  3. Multiply by 100: 109.5238%
  4. Check: Work forwards from the start: 42 × (1 + 1.095238) = 42 × 2.095238 = 88.

In a spreadsheet: =(88-42)/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 2.0952 times the old one: for every 100 at the start there are now 209.5238. The value has more than doubled.

Prices: an item whose price rises from $42 to $88 has gone up by 109.5238%.

Why the change back is different

A 109.5238% rise followed by a 109.5238% fall does not bring you back to 42: it gives -8.381. The second percentage is taken of 88, not of 42, so to undo this change you need 52.2727% instead.
