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 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
