有人曾推荐过一本书:Paying for College without going broke
俺从图书馆借过:Chapter Two, 有一节有一个列表, How much will a college education cost in X years? 例如, for average annual cost of a public university in 2012: $18,119, if 6% growth rate per year, In 2022 (10 year later): it will be $32,448 /per year.
* 4 years; * 2 kids
Private school is more expensive.
Good news: if two kids go school at the same time, "two for one sale", family contribution are the same and you may get more financial aid from school.
