The unsubsidized loan is not based on financial need but total need may not exceed the cost of attendance.
The federal government does not pay the interest while the borrower is in school. All interest is the borrower's responsibility. You will be charged interest from the time the loan is disbursed until it is paid in full. Students can either pay the interest while they are in school or let it accrue. If it is not paid, it is added to the principle (capitalized) when the borrower goes into repayment. If your interest is capitalized, it will increase the amount you have to repay. You can choose to pay the interest as it accumulates; if so, you'll repay less in the long run.
Students must begin repaying this loan 6 months after you cease to be enrolled at least half-time. The interest rate is fixed at 6.8%.
