Deciding when to refinance your student loans comes down to whether you qualify for a lower interest rate. Typically, you need to graduate school before you can apply for a student loan refinance — although there are a few lenders that offer refinancing to those who didn’t earn a degree.
It is generally best to avoid refinancing your federal student loans if you want access to government protections like income-driven repayment and loan forgiveness. However, borrowers who don’t qualify for such programs might save money by refinancing their federal debt if they can secure a lower interest rate.
