The EFC affects need-based aid, so grants and subsidized Stafford loans. Unsubsidized Stafford loans are unaffected by the EFC. In my case, I got the full amount of $8,500 subsidized and $10,000 unsubsidized for my graduate program, but if my EFC had been $9,000 then I would have only been able to borrow $10,000 in the unsubsidized Stafford loans. For a first-year dependent undergrad, the limit is $3,500 subsidized and $3,500 max unsubsidized minus any subsidized loans, so in effect all freshmen can get $3,500 for their first year regardless of their EFC.
