Student loan refinancing means taking out a new loan from a private lender to pay off one or more existing student loans. The new loan has new terms — ideally a lower interest rate, a shorter or longer repayment period, and a single monthly payment.
When you refinance, the new lender pays off your old loans. Your old loans are closed, and you start fresh with the new lender. This is different from consolidation, which combines loans but doesn't change your interest rate.
Refinancing stops capitalization. When you refinance, any accrued interest on your original loans is paid off as part of the refinance. That interest never gets added to your principal. If you're facing an upcoming capitalization event, refinancing can eliminate it entirely.
These terms are often used interchangeably, but they're very different:
| Feature | Refinancing | Consolidation |
|---|---|---|
| Lender | Private lender | Federal (Direct Consolidation) or private |
| Interest Rate | Can lower your rate | Weighted average of existing rates (no savings) |
| Federal Protections | ❌ Lost (if refinancing federal loans) | ✅ Kept (federal consolidation only) |
| Capitalization Impact | ✅ Stops capitalization | ⚠️ Often triggers capitalization |
| Multiple Loans | Can combine multiple loans | Combines multiple federal loans |
| Best For | Lowering rate, stopping capitalization | Simplifying payments, keeping federal benefits |
Consolidation often triggers capitalization. When you consolidate federal loans, any unpaid interest on the underlying loans capitalizes into the new balance. Refinancing pays off the accrued interest, so it never capitalizes. If you're trying to stop capitalization, refinancing is the answer — not consolidation.
Refinancing isn't right for everyone. Here are the conditions that make it a smart move:
On a $30,000 loan at 6.5% APR, refinancing to 4.5% APR saves you about $50/month and $3,000+ over 10 years. If you add the capitalized interest you prevent from accruing, your total savings could be even higher.
Here are the top lenders for student loan refinancing. Rates are updated regularly, so always check current offers.
Credible lets you compare prequalified rates from multiple lenders at once — including SoFi, Earnest, Laurel Road, and more. Your credit score won't be affected by checking your rates.

Your refinance rate depends on several factors. Here's how to put yourself in the best position:
Lenders use your credit score as the primary indicator of risk. 650+ is the minimum for most lenders; 700+ gets you the best rates. If your score is below 650, consider a co-signer or work on building your credit before applying.
If you don't have a strong credit history, adding a co-signer with good credit can significantly lower your rate. Many lenders allow co-signer release after a certain number of on-time payments.
Don't just take the first offer. Rates vary significantly between lenders. Use Credible to compare multiple lenders at once, or apply to 3–4 lenders individually and compare their offers.
Fixed rates stay the same for the life of the loan. Variable rates can change over time — they start lower but can increase. Fixed rates are safer for long-term borrowers.
Longer terms (15–20 years) mean lower monthly payments but more total interest. Shorter terms (5–10 years) mean higher monthly payments but less total interest. Choose based on your cash flow and goals.
Refinancing is powerful, but it comes with trade-offs. Here's when you should NOT refinance:
Once you refinance federal loans, you can't go back. You lose access to income-driven repayment, PSLF, deferment, forbearance, and discharge options. If there's any chance you'll need these protections, don't refinance. Consider the SAVE plan instead.
Refinancing federal loans = losing protections. Only do this if you're certain you won't need IDR, PSLF, or deferment.
Consider SAVE FirstRefinancing private loans carries no risk. You can only gain — lower rate, simpler payment, stop capitalization.
Good CandidateIf your rate is 6%+ and your credit is 700+, refinancing is a no-brainer. You'll save thousands with zero downside.
Strong CandidateYes. When you refinance, the new lender pays off your original loan — including all accrued interest. That interest never gets added to your principal, so it never capitalizes. Refinancing before a capitalization event can save you thousands.
Yes, but you'll lose federal protections. If you refinance federal loans with a private lender, you lose access to income-driven repayment, PSLF, deferment, forbearance, and discharge options. Only refinance federal loans if you're certain you won't need these protections.
Most lenders require a minimum credit score of 650 for approval. For the best rates, aim for 700+. If your score is below 650, consider applying with a co-signer who has strong credit.
Most lenders require you to have graduated or be within 6 months of graduation. You typically need to have a degree and be employed or have a job offer to qualify.
Most refinance applications take 2–4 weeks from application to funding. The process includes credit checks, income verification, and document review. Some lenders can close in as little as 7–10 business days.
Not significantly. Lenders do a hard credit check when you apply, which may lower your score by a few points temporarily. However, most borrowers' scores bounce back within 1–3 months. Shopping multiple lenders within a 2-week window counts as a single inquiry for scoring purposes.
