Remember in season 1 episode 1 when Scott and Stiles are in the woods looking for Scott's inhaler, they meet Derek and Stiles says: "he's only like a couple of years older then us". So that clears up the age thing for Derek. Slightly older than Scott and Stiles who at the moment are 17 ish so that would put Derek at 20. Doesn't seem right, he looks older than 20.
