Don't forget the interest for x years, where x is your current age. You probably think student loans are bad. Student loans aren't in it. It now costs around $300,000 to raise a child to age 18, and that's just out-of-pocket expenses by the parents. That doesn't count all the schools and societal infrastructure that are paid for either by taxes on the parents (and non-parents!) or by direct payments.

Also don't forget that you, too, will be old. A lot sooner than you probably think.
