A student loan is a way for a person matriculating in higher education to borrow money from either the government or a private banking institution to pay for their education. Typically, as long as a student is enrolled in an accredited university and is meeting the minimum credit requirements, the repayment of the student loan is deferred until after graduation.
Those looking for a student loan with low interest rates are advised to first complete a Free Application for Federal Student Aid and see if they can get any loan money from the government. However, the amount of money the Feds loan is capped by congress, so additional loans through a private bank will probably be necessary.
By taking the time to compare the student loan interest rates offered by a variety of banking institutions, a student or their benefactor can help locate the best rate available to them.
