Second, more and more public research has been conducted on student expenses, enabling upcoming students to understand their potential expenses by looking at trends as a whole. Researching what others borrow is key to figuring out how much you should borrow, and enables you to narrow down what sort of range you should apply for. Making sure you borrow something close to what's expected also helps reduce your risk, since it will more closely match you with what you anticipate your industry of choice will enable you to pay back.
Third, it's important to know yourself. Some people can live on store-brand coffee while others will be too miserable to function without daily visits to coffee shops. Look at your own expenses and see what you really spend on yourself - the number may be surprisingly high. Talk to your parents and see what they spent on you in high school, and compare that with your own bills, budgets and spending habits. Accounting for living expenses is one of the most intractable parts of attending college, and borrowing enough to keep yourself comfortable, without overreaching your ability to repay is very important.
In the end, you should borrow an amount that allows you to live comfortably, but that you are comfortable with. If the number looks a little high, it probably is. So don't hesitate to talk to others about what they borrowed, and how they spent it. You may save thousands in the long run.
