Note that the lower the interest rate, the less pricey the student loan is. This actually means, the less you will have to repay for your student loan debt.
For your own sake, here is what your batting order should be (from the least expensive):
Student Loans
1. Federal Perkins Loans
2. Federal Subsidized Stafford or Direct Loans
3. Federal Unsubsidized Stafford or Direct Loans
4. Alternative or Private Loans
As you may know, most of the students thinking for student loans have access to a special loan source these days. These sources, like the Air Force Aid Society, have student loans terms that are comparable to the Perkins or Subsidized Stafford or Direct Loans. Of course, it may be worth your time to look into the possibilities. There are some sources these days that offer low-interest student loan programs, and perhaps one of the most resourceful is the College Board’s online Scholarship Search.
