REFINANCING STUDENT loans can save you money under the right circumstances. It could be helpful to score a lower interest rate, to change from a variable interest rate to a fixed rate, to consolidate your loans for a single monthly payment, or to release a co-signer.

At the same time, you could lose protections and benefits from your original student loan. Before you refinance, make sure you understand your choices, including any trade-offs.
