Refinancing your student loans is free. Any reputable lender won't charge application or origination fees. Nor will they charge prepayment penalties if you pay off your loans early. If you have federal loans, you can consolidate through the Department of Education for free as well. Avoid companies claiming that you need to pay to refinance with them. They are most likely a scam. There are tons of student loan scams out there so make sure you aren’t paying anything for refinancing.
