As a result of the federal government deal to raise the debt ceiling, graduate and professional students are seeing the last year of fully subsidized federal loans. Beginning next July, only the first $8,500 will have deferred interest. After that, the interest kicks in immediately. "If students let interest accrue, they'll pay about 16 percent more when they actually go to repay the loan. And over the life of the loan, that will probably be about a six percent increase or somewhere between $2,000 and $4,000 while they're in school," said John Morris of Temple's Office of Student Financial Services.
