The maximum amount that any student can borrow is adjusted as federal policies change. Current loan limits are below the cost of most four year private institutions and most flagship public universities, and students therefore typically borrow higher cost private student loans to make up the difference. Scholars have advocated increasing federal debt limits to reduce the interest charges to student debtors.
The maximum amount that any student can borrow is adjusted as federal policies change. A study published in the winter 1996 edition of the Journal of Student Financial Aid, "How Much Student Loan Debt Is Too Much?" suggested that the monthly student debt payment for the average undergraduate should not exceed 8% of total monthly income after graduation. Some financial aid advisers have referred to this as "the 8% rule." Circumstances vary for individuals, so the 8% level is an indicator, not a rule set in stone. A research report about the 8% level is available at the Iowa College Student Aid Commission.
The Economist reported in June 2014 that U.S. student loan debt exceeded $1.2 trillion, with over 7 million debtors in default. Public universities increased their fees by a total of 27% over the five years ending in 2012, or 20% adjusted for inflation. Public university students paid an average of almost $8,400 annually for in-state tuition, with out-of-state students paying more than $19,000. For two decades ending in 2013, college costs have risen 1.6% more than inflation each year. Government funding per student fell 27% between 2007 and 2012. Student enrollments rose from 15.2 million in 1999 to 20.4 million in 2011, but fell 2% in 2012.
