Although both can help you with your education expenses, private and federal student loans are entirely different financial products. Private financial institutions fund the former, including banks, online lenders and credit unions. The U.S. government backs federal loans.
Refinancing your student loans can be a good strategy for debt management. It may allow you to find better rates or shorter loan terms. However, while you can use a private student loan to refinance a federal one, the opposite isn't possible.
That said, several lenders have benefits similar to those offered by federal loans. You can still enjoy some perks with a private loan refinance.
