While I do agree that '5 years' means something different for everyone, I would also advocate spending the most on a new helmet versus a formerly nicer used helmet. My riding tends to kill helmets at the 2-3 year mark, and what I spend on new helmets is based on that.
Also, if you are asking about your helmets 'expiration' before you have fully trashed it, you aren't riding enough.
