Every borrower is constantly looking for ways to lower their interest rates. While everyone can do Direct Debit and receive the 0.25% interest rate reduction, there are programs available to members of the military exclusively.
The one that is the most known in the Servicemembers Civil Relief Act. This one has gotten a lot of attention in the news recently due the case with Sallie Mae and their massive fine that resulted in not implementing it correctly. In order to qualify for this interest rate reduction you must be an active duty military member. Those who are retired or are spouses, children, etc of active members are not eligible for this. With this act you are able to cap any interest you have at 6%.
In some cases (though more rare) you can also qualify for 0% interest on all loans. While a borrower is serving in a hostile area that would qualify him or her for special pay, he or she additionally does not have to pay interest on Direct Loans made on or after October 1, 2008. This status can be for up to 60 months.
