Both types offer a grace period of six months, which means that no payments are due until six months after graduation or after the borrower becomes a less-than-half-time student without graduating. Both types have a fairly modest annual limit. The dependent undergraduate limit effective for loans disbursed on or after July 1, 2008 is as follows (combined subsidized and unsubsidized limits): $5,500 per year for freshman undergraduate students, $6,500 for sophomore undergraduates, and $7,500 per year for junior and senior undergraduate students, as well as students enrolled in teacher certification or preparatory coursework for graduate programs. For independent undergraduates, the limits (combined subsidized and unsubsidized) effective for loans disbursed on or after July 1, 2008 are higher: $9,500 per year for freshman undergraduate students, $10,500 for sophomore undergraduates, and $12,500 per year for junior and senior undergraduate students, as well as students enrolled in teacher certification or preparatory coursework for graduate programs. Subsidized federal student loans are only offered to students with a demonstrated financial need. Financial need may vary from school to school. For these loans, the federal government makes interest payments while the student is in college. For example, those who borrow $10,000 during college owe $10,000 upon graduation.
