- A 2% APR drop on $50,000 over 10 years saves $52 a month and $6,240 over the life of the loan (real math, not an estimate).
- Refinancing federal loans into a private loan permanently eliminates income-driven repayment, PSLF eligibility, federal forbearance, and discharge protections. These cannot be restored.
- Lenders vary significantly by credit score fit: strong-credit borrowers (740+) get the best rates at SoFi and Earnest, while cosigner-friendly lenders like College Ave open the door for thinner files.
The bottom line
Student loan refinancing can reduce your interest cost meaningfully if you have private loans or federal loans you are certain you will not need protections for. The math is straightforward: lower APR means less total interest paid. The risk is equally straightforward: refinancing federal loans is a one-way door. You permanently give up every federal protection the moment you close a private refinance loan. Read the federal loan warning section below before you do anything else.
Quick picks
| Best for | Pick | Why |
|---|---|---|
| Strong credit (740+) | SoFi | Competitive APR range, no fees, career support |
| Cosigner options | College Ave | Flexible cosigner release after 24 payments |
| Medical / dental / law | Laurel Road | Specialty programs with grace periods for residents |
| Parent loan refinance | SoFi | Accepts Parent PLUS refinance into parent's name |
| Flexible term lengths | Earnest | Custom term from 5 to 20 years, bi-weekly payment option |
| Low fees | ELFI | No application, origination, or prepayment fees |
What a 2% APR difference actually costs you
Starting balance: $50,000. Loan term: 10 years (120 months).
At 8.00% APR: monthly payment $607, total paid $72,840, total interest $22,840.
At 6.00% APR: monthly payment $555, total paid $66,600, total interest $16,600.
Difference: $52 per month, $6,240 over the life of the loan.
This is the value of a 2-point APR improvement for a typical graduate borrower. For larger balances or longer terms the savings compound further. A $100,000 balance at the same spread saves $104 a month and roughly $12,480 over 10 years.

Federal loan protections you permanently lose when you refinance
This is the most important section in this guide. If you have federal student loans, read it fully before comparing lenders.
When you refinance federal loans into a private loan, the U.S. Department of Education is no longer your lender. You permanently and irrevocably lose:
- Income-driven repayment (IDR): Plans like SAVE, IBR, PAYE, and ICR cap monthly payments at 5% to 20% of your discretionary income. Your payment can be $0 in low-income years and you remain in good standing. Private lenders do not offer this.
- Public Service Loan Forgiveness (PSLF): Government and qualifying nonprofit employees can have remaining federal loan balances forgiven after 120 qualifying monthly payments (10 years). Forgiveness is tax-free. Once you refinance into a private loan, PSLF eligibility is gone.
- Federal forbearance and deferment: Federal loans allow up to 3 years of economic hardship deferment and other pauses. Private lenders offer forbearance at their discretion, typically 12 months maximum, and interest usually accrues during that pause.
- Discharge programs: Federal loans can be discharged if your school closes, if you become permanently disabled (Total and Permanent Disability Discharge), or in limited bankruptcy circumstances. Private loans have far narrower discharge rights.
- Death discharge: Federal loans are discharged if the borrower dies. Most private loans are not automatically discharged, meaning the estate or a cosigner may remain liable.
Do not refinance federal student loans if you work or plan to work in government, education, nonprofits, or any qualifying public service field. PSLF can forgive six-figure balances tax-free after 10 years of payments. A 2% APR improvement is not worth giving that up. If you are unsure, use the studentaid.gov PSLF Help Tool before you apply anywhere.
Do not refinance if any of these apply to you
- You work or plan to work in a PSLF-qualifying job (government, nonprofit, public school, public hospital).
- Your income is low or unpredictable and you may need IDR to keep payments affordable.
- You are currently in school or have a grace period and your federal loans are not yet in repayment.
- You have Parent PLUS loans you intend to put on Income-Contingent Repayment through double-consolidation (a specific federal strategy that private loans cannot replicate).
- You have a history of financial instability and may need forbearance or deferment beyond what private lenders offer.
Credit score fit matrix
| Score range | Best lender options | What to expect |
|---|---|---|
| 760+ | SoFi, Earnest, ELFI | Likely qualify for lowest published APRs; no cosigner needed |
| 720 to 759 | SoFi, Earnest, Splash Financial | Competitive rates; strong approval odds without cosigner |
| 680 to 719 | College Ave, Splash Financial | Mid-range APRs; cosigner can meaningfully lower rate |
| 650 to 679 | College Ave with cosigner | Approval likely requires cosigner; rates will be higher |
| Below 650 | Unlikely to qualify unassisted | Focus on credit building first; consider a creditworthy cosigner |
Credit score alone does not determine approval. Lenders also review debt-to-income ratio, employment status, degree completion, and monthly cash flow. Verify current eligibility criteria directly with each lender.
Variable vs. fixed rate: which to choose
Fixed rates lock in your APR for the full loan term. Your payment never changes. Fixed is usually the right choice if you plan to keep the loan for more than 3 to 4 years or if you cannot absorb payment increases.
Variable rates are typically lower at origination but reprice periodically (monthly or quarterly) based on a benchmark index such as SOFR. If rates fall after you close, your payment drops. If rates rise, it increases. Variable rates can save money on short terms (under 5 years) or if you plan to pay off aggressively, but they add meaningful payment uncertainty.
Break-even on fees
Most top refinance lenders charge no origination fee, but always verify. If a lender charges a fee, calculate your break-even before signing: divide the total fee by your monthly savings. If a lender charges $500 and you save $52 a month, break-even is about 10 months. If you plan to pay off or refinance again before that, the fee erases the benefit.
Top picks, detailed
SoFi: Best for strong credit and no fees
SoFi refinances both student loans and Parent PLUS loans. It charges no origination fee, no prepayment penalty, and no late fee. Members get access to career coaching and unemployment protection that temporarily pauses payments while you job-search. SoFi requires a degree from an eligible school and generally targets borrowers with stable income and strong credit. Verify current APR ranges and eligibility at sofi.com, as rates change with market conditions.
Who should apply: Borrowers with a 720+ credit score, steady income, and private loans (or federal loans they are certain they will not need federal protections for). Also the best option if you want to refinance Parent PLUS loans into the parent's name.
Who should skip: Federal loan borrowers who may need IDR or PSLF. Borrowers with thin credit history who need a cosigner (SoFi's cosigner release terms require confirmation directly with the lender).
Earnest: Best for flexible terms
Earnest lets you choose any loan term from 5 to 20 years, rather than locking you into preset 5-, 7-, 10-, 15-, or 20-year buckets. You can also make bi-weekly payments, which can shave months off the loan and reduce total interest without refinancing again. Earnest reviews more than your credit score, weighing savings, spending patterns, employment, and education as part of its underwriting.
Main terms: No fees, no prepayment penalty, flexible term selection, bi-weekly payment option. Verify current APR ranges at earnest.com.
Who should apply: Borrowers who want precise term control, plan to pay aggressively, or have a solid financial profile that a credit score alone undersells.
Who should skip: Borrowers who need a cosigner (Earnest does not currently offer cosigner loans for student refinancing in all states; verify directly). Federal loan borrowers with PSLF potential.
Laurel Road: Best for medical, dental, and law borrowers
Laurel Road offers specialty refinancing programs for medical residents, dental residents, and fellows. During residency, borrowers can pay a reduced monthly amount (verify current minimums at laurelroad.com) rather than a full amortizing payment, then step up to standard payments after training ends. This is meaningfully different from deferment: payments are low but the loan is active, which builds credit and keeps balances from growing as fast as pure capitalization.
Laurel Road also offers discounts for KeyBank checking account holders.
Who should apply: Medical, dental, or law graduates with high balances and time-limited earning constraints during training or early practice.
Who should skip: Undergraduate borrowers without specialty training circumstances. Anyone considering NHSC, PSLF, or other federal loan forgiveness programs tied to public-sector healthcare work.
ELFI: Best for low fees and straightforward terms
ELFI (Education Loan Finance) is a division of SouthEast Bank and focuses on student loan refinancing with no application fee, no origination fee, and no prepayment penalty. ELFI assigns a personal loan advisor who can walk through options by phone, which some borrowers prefer to a purely digital process. Verify current APR ranges and eligibility at elfi.com.
Who should apply: Borrowers who want no-fee refinancing and value human support during the process.
Who should skip: Borrowers who need a cosigner release with a short timeline (verify cosigner release terms directly with ELFI). Federal loan borrowers with forgiveness potential.
College Ave: Best for cosigner options
College Ave allows cosigners on refinance loans and offers a cosigner release after 24 months of on-time payments, subject to credit review. This is one of the more accessible release timelines among top lenders. College Ave also offers a wide range of repayment terms and is available in all 50 states. Verify current APR ranges and eligibility at collegeave.com.
Who should apply: Borrowers with a credit score in the 650 to 720 range who have a creditworthy cosigner available, particularly parents or spouses with strong credit.
Who should skip: Borrowers who do not have a cosigner and whose solo credit profile is below 680. Federal loan borrowers with PSLF potential.
Splash Financial: Best marketplace comparison
Splash Financial is a marketplace that matches borrowers with multiple lenders from a single application, letting you see several rate offers without multiple hard inquiries in the initial rate-check step. This is useful for borrowers who are unsure which lender will give them the best terms. Verify which lender partners Splash is currently working with at splashfinancial.com, as partnerships change.
Who should apply: Borrowers who want to comparison-shop without filling out multiple applications.
Cosigner release: what it means and how it works
A cosigner release removes your cosigner's liability and their association with the loan after you meet the lender's requirements, typically a set number of consecutive on-time payments (commonly 12 to 48 months depending on lender) plus an income and credit review at the time of release.
Until the release is granted, the cosigner is equally liable for every dollar of the loan. The loan appears on their credit report. If you miss payments, it damages their credit. If you default, the lender can collect from them directly. This is a significant commitment to ask of any cosigner, particularly a parent who may have their own retirement, mortgage, or healthcare costs to manage.
Always confirm the exact cosigner release requirements with the lender in writing before accepting a loan with a cosigner.
When this recommendation changes
The lender rankings shift if: (1) the Fed changes the federal funds rate significantly, causing variable-rate products to reprice and the spread between lenders to widen; (2) a lender changes its underwriting criteria or fee structure; (3) you move into a job that qualifies for PSLF (federal loans become far more valuable than any refi savings); (4) your credit score improves significantly after initial comparison, which can unlock materially better rates. Re-run your quotes annually or whenever your credit profile changes.
How to calculate your break-even before applying
- Get your current loan's monthly payment and remaining balance.
- Use the student loan payoff calculator below to estimate your new monthly payment at the refinanced rate.
- Subtract new payment from current payment to get monthly savings.
- Add up any lender fees.
- Divide total fees by monthly savings. That is your break-even in months.
If you plan to keep the loan past that point, refinancing is likely worth it on a pure cost basis (assuming you have private loans or have made the PSLF/IDR decision).
