I actually don't, those are the only two expenses my family has. Come to think of it those are the only two expenses I've ever had. I guess if we lived in the countryside we'd need a car, so, three expense categories total.
But alright, gather all of these other miscellaneous expenses up and take out another $10k per year to cover them. You still have $30,000 left if you're paying $2k a month on rent.
