With our son, the price calculator included things like $1,000 a year for books and supplies, $2000 a year for “transportation,” etc. We rented nearly all of his textbooks from Chegg; that MAY have added up to $1,000 over all five years. Certainly not $1,000 per year. And he went to a college 15 miles from home. He did live on campus, so we had room and board to pay for, but he did not need an extra $2000 a year; that might apply for a student who is across country and needs to fly home for Christmas, etc.
So, even when a school includes some dollar amount for an item, look at that item and see if it would apply to your student. It might …but it won’t always.
I would also point out that when I went to college years ago, tuition was charged by the hour. So if you took 14 hours one semester and 18 hours the next semester, the 18-hour semester would have a higher tuition bill. Son’s college charges one tuition amount for ANY number of credit hours from 12 to 18. So, if he had taken 18 hours every semester, we would have gotten more bang for our buck. Make sure you look at that, as well.
