Federal vs. private student loans

Scenario. $20,000 borrowed over 10 years. The federal rate shown (6.5%) is fixed by law and identical for every borrower regardless of credit; the private rate (7.5%) assumes a fair-to-good credit borrower without a cosigner. A borrower with excellent credit or a strong cosigner could see a private rate below the federal one — the private side is genuinely risk-based, unlike the federal side.

Why federal loans are the default first choice

Federal student loan rates are fixed annually by law and are identical for every borrower — there's no credit check for most federal loan types (Parent PLUS is the exception), so a student with no credit history at all still qualifies at the same rate as anyone else. That rate comes bundled with income-driven repayment, forgiveness programs like Public Service Loan Forgiveness, and broad deferment and forbearance rights if income drops or a hardship hits.

None of that comes with a private loan, which is why nearly every guide to paying for college says the same thing: exhaust federal borrowing first, and only then consider a private loan for whatever's left.

When a private loan makes sense

  • You've borrowed the federal maximum for your year in school and still have a funding gap.
  • You (or a cosigner) have excellent credit and can qualify for a rate meaningfully below the current federal rate — this genuinely happens, since the federal rate is fixed regardless of creditworthiness.
  • You're refinancing after graduation, with stable income and established credit, and have decided you won't need income-driven repayment or forgiveness eligibility.

Frequently asked questions

Should I take federal loans before private ones?
Yes, for nearly everyone. Federal loans have a fixed rate, little or no credit check, and access to income-driven repayment and forgiveness programs no private lender offers. Use private loans only to cover a gap after maxing out federal borrowing.
Can a private loan really have a lower rate than a federal loan?
Yes, for a borrower with excellent credit or a strong cosigner — private rates are risk-based, so the best-qualified borrowers can undercut the federal rate. Most students, borrowing with little or no credit history of their own, won't qualify for a private lender's best rates.
Should I refinance federal loans into a private loan?
Only after weighing what you give up: income-driven repayment, forgiveness eligibility, and federal deferment and forbearance rights all disappear the moment a federal loan is refinanced into a private one, permanently. It can make sense for a borrower with stable income who won't need those programs and qualifies for a meaningfully lower rate — but the decision can't be reversed.
