That's the hardest part for me to figure out as well. I'm a compulsive saver so I have a pretty good chunk of cash in a savings account and stocks but I'm struggling to figure out how much of that I should use and how much I should take out in student loans. That was my whole purpose for putting together a budget for the first year. I'm leaning towards more loans my first year while I figure out what the cashflow will be like and then adjust my second year. I also want to leave a decent chunk in savings if I can just in case I'm hunting for a job after graduation, student loans can't cover that gap.
The interest for non-subsidized student loans in the USA range from 6.8%-9% APR for Federal government student loans and possible much higher for private student loans. I doubt that you can achieve a 6.8%-9%
after tax return on any of your investments without taking lots of risk. Therefore I suggest using all of your savings, bar a small chunk of cash reserves for emergencies, and taking on as little debt as possible.
If everything goes according to plan you should have a job offer secured by the first half of your second year. If you don't have a job secured by then, then you always have the option of taking out a personal loan at 8-10% APR up to a few tens of thousands of USD, if you have good credit, to carry you over until you do find a job.
Obviously you want to take advantage of as much subsidized loans as possible, since for those type of loans the government pays your interest while you are in school.
