Wow! Such a big question! Let’s start by making a key distinction:
(1) One might interpret this question as, “How much does a university charge the student and parents?” Allowing for such significant complications as different sticker prices at different universities, different financial aid packages for different students at the same university, different fees for different majors, additional charges (primarily from rising tuition prices) in the sophomore, junior and senior years – it is nonetheless the case that, when the incoming freshman arrives on campus, he or she (and the parents) know fairly accurately what their out-of-pocket costs will be, at least for the first year. So while this is an important question, and answering it can be confusing and time-consuming, in the end it is answerable. But consider the second alternative.
