Refinancing can save money, but it can also remove federal protections that matter more than rate reduction for some borrowers.
When refinancing looks attractive
Lower interest rates and simpler repayment can be compelling if your income is stable and you do not rely on federal safety-net features.
When caution matters
Federal loans may offer repayment flexibility, forgiveness paths, or hardship protections that private refinancing removes.
Bottom line
Refinancing is most attractive when the savings are meaningful and the protections you give up are not likely to matter for your situation.
