Quick overview
Private student loan refinancing replaces one or more existing student loans (private, federal, or both) with a new loan from a private lender. The lender pays off your old loans and you begin paying the new loan under its interest rate and terms. Many borrowers refinance to lower interest rates, shorten or lengthen terms, or remove a cosigner. But refinancing isn’t free from tradeoffs — most notably the loss of federal borrower protections and potential changes to tax and credit outcomes. (Federal Student Aid, studentaid.gov; Consumer Financial Protection Bureau, consumerfinance.gov)
Why people refinance: common goals
- Lower the interest rate to reduce interest paid over the life of the loan.
- Reduce monthly payments by extending the term.
- Shorten the term to pay the loan off sooner and save interest.
- Simplify multiple payments into one loan.
- Remove a cosigner when credit history has improved.
Key risks to understand
- Loss of federal protections: If you refinance federal student loans with a private lender you usually give up access to income-driven repayment plans, federal deferment and forbearance options, and eligibility for Public Service Loan Forgiveness (PSLF). That can cost far more than interest savings for some borrowers. (Federal Student Aid)
- Variable-rate risk: Many private loans offer variable rates that can start low and rise later. If rates increase, your monthly payment and total interest can spike.
- Longer term may increase total cost: Extending the repayment term lowers monthly payments but often increases total interest paid over the life of the loan.
- Fees and prepayment penalties: Some private lenders charge origination fees or penalties. Compare APR and the full fee schedule before signing.
- Credit and cosigner effects: Refinancing requires underwriting; a hard credit pull can temporarily lower your credit score. If you involve a cosigner (or release one later), consider their credit and legal exposure.
- Loss of borrower protections in hardship: Private loans rarely offer the same generous hardship programs federal loans do (forbearance, administrative forbearance, loan rehabilitation).
How refinancing can save money — a simple example
Example (illustrative only): You have $40,000 at 7% fixed, 10-year original term. Monthly payment ≈ $465. If you refinance to 4% fixed for the remaining 10-year term, monthly payment ≈ $405 and total interest over the term falls substantially. If you instead extend to 15 years at 4%, monthly payment drops further but total interest paid increases. Use an online loan calculator and compare APRs and fees.
Tip: Always compare APR rather than only the nominal interest rate. APR factors in fees and gives a truer cost comparison across lenders.
Who typically qualifies
Lenders review: credit score, steady income, debt-to-income ratio (DTI), employment history, and sometimes cash reserves. Typical competitive rates are offered to borrowers with higher credit scores and low DTI. If you lack credit history or steady income, a cosigner may help you qualify but it creates obligations for that cosigner.
When refinancing makes sense (decision checklist)
- You have only private loans, or you are comfortable losing federal benefits.
- You can get a materially lower APR (generally a full percentage point or more) or better loan terms.
- You don’t plan to pursue PSLF or rely on income-driven repayment.
- You already have an emergency fund and stable income to support repayment.
- You’ve compared fixed vs variable rates and understand future rate risk.

Step-by-step refinancing process
- Gather loan statements and verify balances, interest rates, and servicers.
- Check your credit reports and scores (annualcreditreport.gov). Improve credit if possible before applying.
- Shop lenders—get prequalified rates from multiple lenders to compare offers without hard pulls.
- Compare APR, fixed vs variable rates, fees, repayment terms, and borrower benefits (cosigner release, autopay discounts).
- Apply to your chosen lender; expect a hard credit pull during underwriting.
- Sign loan documents and confirm the lender will pay off your existing loans.
- Verify old loans are closed and watch the first billing statement from the new lender.

Cosigners: special considerations
- Cosigners are common when the primary borrower has limited credit or income. A successful refinance may allow cosigner release later, but terms vary by lender.
- Cosigners are legally responsible for repayment. If the borrower misses payments or defaults, the cosigner’s credit and finances are at risk.
- If you plan to remove a cosigner, verify the lender’s release policy in writing before refinancing.
Tax and credit consequences
- Student loan interest may be tax-deductible for eligible borrowers; changing the loan holder doesn’t usually change deductibility but always verify eligibility and limits with IRS guidance (see IRS Publication 970).
- Refinancing can temporarily lower your credit score due to a hard inquiry and changes in average account age; long-term effects depend on payment history with the new lender.
Professional tips from practice
- In my practice, I advise clients with mixed federal and private portfolios to refinance only their private loans and leave federal loans in place unless they understand and accept the tradeoffs.
- Don’t chase a slightly lower rate if it costs federal protections you might need later — the value of forgiveness programs or income-driven plans can exceed rate savings.
- Ask lenders for a written payoff letter, confirm the payoff timeline, and maintain proof that the old loans were paid.
- If your credit is marginal, improving credit (reduce balances, correct errors) before applying can improve offers substantially.
What lenders won’t tell you up front
- How future rate movements on variable loans will affect long-term cost.
- That some underwriting standards (like DTI calculations) differ across lenders; shopping multiple lenders matters.
- That removing a cosigner is not guaranteed — always check the lender’s policy.
Frequently asked questions (brief)
- Can I refinance federal loans? Yes, but you typically forfeit federal borrower benefits. Check Public Service Loan Forgiveness and income-driven eligibility before deciding. (studentaid.gov)
- How often can I refinance? You can refinance multiple times, but each refinance triggers new underwriting and may cost fees or hard credit pulls. Wait until your financial profile improves when possible.
- Is refinancing right if I plan to work in public service? Usually no — PSLF requires federal loans in qualifying repayment programs. Refinancing federal loans makes them ineligible for PSLF.
Red flags and lender selection
- Heavy origination fees or prepayment penalties.
- No cosigner release policy if you’re refinancing with a cosigner.
- Variable-rate products without clear index and cap disclosures.
- Poor customer service reviews regarding loan servicing and forbearance handling.

Final takeaways
Refinancing private student loans can lower your interest rate and simplify payments, and for borrowers with strong credit and no need for federal protections it’s often beneficial. But refinancing federal loans is irreversible in many cases and can remove valuable protections that may be worth more than the interest savings. Always run the numbers, compare APRs and fees, consider your long-term career and financial plans, and consult a financial advisor if you’re unsure.
