The things I remember most fondly from college didn't require money -- or they were very low-cost outings. My favorite memories of college involve just hanging around the dorms, attending free school concerts and dances, ball games, week-long games of Assasin, the time it snowed (a rarity for us) and we went sledding on cafeteria trays, fifty cent hot dogs every Sunday evening. We ate the great majority of our meals in the cafeteria, and when we went out it was almost always the $1 movie theater. We went camping a couple times; we could rent tents for $4 back then.
I think a great deal of this budget question has to do with how you've raised your child for the first 18 years of her life. My daughter has been raised knowing that all her needs will be met, but she hasn't always had the newest and the best of everything (i.e., she wants a Smart Phone, but I said too expensive). She's been raised frugally and won't find it a chore to continue to live that way in college. In contast, I was talking to a teacher friend whose daughter just finished her freshman year in college, and I asked her what I ought to know about money . . . she said it's been awful -- a constant issue between them (the mom is working a part-time job in addition to teaching school, but her daughter isn't working , not even this summer -- not the way we'd do things in our house). BUT I remember running into her last summer at the mall, and she was definitely decking her daughter's dorm room out in style. Now she's re-doing it all because she's leaving the dorms for an apartment and "needs" new stuff. She said the sorority was running her into the poor house, and she wished she'd allowed her daughter to join. Anyway, she complains, BUT that's the way she's always treated her daugther: She had a hand-me-down car at 16, a new car for graduation, always very nice new clothes. The girl's a nice kid, but she is spoiled rotten. So it's no surprise that she's continuing to allow her daughter to think she has a money tree in the backyard. Okay, I'm rambling: The point is that you've already raised your child to consider the costs of things, or you haven't -- and that plays into how you and she will view her college budget.
