Should you refinance your student loans?
Refinance private loans when you can get a lower fixed rate; refinance federal loans only if you'll never need federal protections.
New to this?
Refinancing a student loan means a private lender, like a bank or credit union, pays off your current loans and gives you one new loan with a new rate and term. People do it to get a lower interest rate. If the old loans were federal, they stop being federal, and that change can't be undone.

Myth
Refinancing and federal consolidation are the same thing.
Truth
Federal consolidation keeps your loans federal at about the same rate. Refinancing is a new private loan. Alex's $40,000 private loan at 9% saves $6,301 by refinancing to 6.5%.
Worth memorizing
- 1
Refinancing federal loans can't be reversed.
Once a private loan pays them off, income-driven plans, federal deferment, forbearance and forgiveness programs are gone for those loans.
- 2
Private loans have the least to lose.
Alex refinanced $40,000 from 9% to 6.5% over 10 years. His payment fell $53 and interest fell $6,301.
- 3
Compare APR, term and rate type.
A lower payment can come from a longer term, not a lower rate. A variable rate can rise later.
Here's what I'd do. Refinance private loans whenever a fixed rate is clearly lower and the term doesn't stretch out. For federal loans, I'd wait until my job, savings and income were steady enough that I'd never need an income-driven plan, and I'd still think twice.
Do this today
List every student loan with its balance, rate and whether it is federal or private. StudentAid.gov shows federal loans, and your credit report shows private ones. For private loans with rates above current offers, get two or three prequalified quotes with the same term.

Which is true of a federal Direct Consolidation Loan?
A Direct Consolidation Loan is federal. Its rate is a weighted average of your old rates, rounded up, and it can't be reversed.
2 of 3
A $40,000 loan costs $20,804 in interest at 9% and $14,503 at 6.5% over 10 years. How much does refinancing save?
$20,804 − $14,503 = $6,301 in interest saved, as long as the term stays at 10 years.

Which borrower has the most to lose by refinancing federal loans?
Public Service Loan Forgiveness only applies to federal Direct Loans. Refinancing them privately ends that path.
Tips
Get prequalified quotes first
Many lenders show an estimated rate after a soft credit check, which doesn't affect your score. Compare several before you formally apply.
Keep your rate shopping short
FICO scores ignore student loan inquiries in the 30 days before scoring and group them made within a 14 to 45 day window into one, depending on the score version.
Keep the term the same
Ask for a term no longer than the time left on your current loans. A longer term lowers the payment but can wipe out the interest you meant to save.
Ask about cosigner release
If a parent cosigned your private loans, a refinance in your name alone can take them off the debt. Check that you qualify on your own income and credit.
A worked example: refinancing a private loan
Alex owes $40,000 in private student loans at an assumed 9% fixed, with 10 years left. A lender offers 6.5% fixed for the same 10 years.
- At 9%, 120 payments of $506.71 repay $40,000 with $20,804 in interest. At 6.5%, 120 payments of $454.20 cost $14,503 in interest.
- The payment drops by about $53 a month, and total interest falls by $20,804 − $14,503 = $6,301.
- These are private loans, so Alex gives up no federal plans. He checks the new loan for fees and confirms the rate is fixed before signing.
- Payment at 9%, 10 years$507
- Payment at 6.5%, 10 years−$454
- Lower payment each month=$53
- Interest at 9% over 10 years$20,804
- Interest at 6.5% over 10 years−$14,503
- Interest saved=$6,301

Common mistakes
Refinancing federal loans on impulse
A rate ad can make it look like free money. Once your federal loans are paid off by a private lender, you can't move them back, and income-driven plans and forgiveness are gone.
Stretching the term
Going from 10 years to 20 can lower the payment even at the same rate, but you pay interest for twice as long. Compare total interest, not just the monthly bill.
Taking a variable rate without a plan
A variable rate tied to market rates can rise. If you choose one, plan to pay the loan off quickly, before rates have long to change.
Going deeper
Refinancing makes the most sense for private student loans when a lender offers a lower fixed rate, because you give up little. For federal loans, refinancing with a private lender ends federal protections like income-driven plans and forgiveness for good, so the lower rate has to be worth losing them.
Refinancing is a new private loan
A private lender pays off your loans and you owe the lender instead. The new rate depends on your credit, income and the term you pick, and it can be fixed or variable.
Federal benefits end
The CFPB lists what federal borrowers lose: income-driven repayment, federal deferment and forbearance, cancellation and forgiveness programs such as Public Service Loan Forgiveness, and in some cases discharge at death or disability.
Consolidation is different
A federal Direct Consolidation Loan combines federal loans and keeps them federal. Its rate is the weighted average of your old rates, rounded up to the nearest one-eighth of a percent, so it doesn't save interest.
Savings come from the rate
Refinancing helps when the new fixed rate is lower and the term is the same or shorter. On $40,000 over 10 years, 9% versus 6.5% is a $6,301 difference in interest.
Refinancing and consolidation
The words get mixed up, and the difference matters. Refinancing means a private lender gives you a new loan to pay off old ones. Your old loans, federal or private, are paid off and replaced by a private loan with the lender's terms.
A Direct Consolidation Loan comes from the US Department of Education. It combines federal loans into one federal loan, with one bill and a fixed rate based on the old ones. It keeps federal protections, but under the One Big Beautiful Bill Act a consolidation loan made on or after July 1, 2026 counts as a new loan. That limits all your Direct Loans to the Repayment Assistance Plan or the Tiered Standard Plan, so check the rules on StudentAid.gov first.
When refinancing usually makes sense
Private student loans are the clearest case. They don't come with federal repayment plans, so swapping a high rate for a lower fixed rate mostly just saves money. Many people took private loans as students with little credit history, and a few years of on-time payments and a steady job can bring a better offer.
Refinancing federal loans can also cut interest if your rate is high, your income is stable, your emergency fund is solid and you're sure you won't need an income-driven plan, a pause in payments or forgiveness. That is a lot of things to be sure of for 10 years or more.
What federal borrowers give up
Federal loans let you tie the payment to your income, which can be as low as $10 a month on RAP. They offer deferment and forbearance if you lose a job, and forgiveness through Public Service Loan Forgiveness after 120 qualifying payments while working for a government or nonprofit employer.
After a private refinance, none of that applies. The CFPB notes that private lenders may still offer some forbearance, and many but not all discharge the loan if the borrower dies or becomes permanently disabled. Active duty servicemembers may also lose the 6% interest rate cap under the Servicemembers Civil Relief Act.
Federal loans can have a perk of their own. StudentAid.gov says that from July 1, 2026 through June 30, 2028, auto pay cuts the rate by 1% on eligible Direct Loans for borrowers enrolled by Dec. 31, 2026. Count that before you compare offers.
How to compare offers
Line up each offer with the same term and compare the APR, which includes fees. Check whether the rate is fixed or variable. A variable rate can start lower and climb above your old fixed rate later.
Watch the term. The lowest advertised rates often come with shorter terms and higher payments. A longer term lowers the payment but adds interest. Also check for origination fees and what the lender offers if you lose your job.
If you mix student loans with other debt in one refinance, the CFPB warns the new loan may no longer qualify for the student loan interest tax deduction.
Questions people ask
Does refinancing student loans hurt your credit?
A little, for a short time. Prequalified quotes usually use a soft check, which doesn't count. A formal application is a hard inquiry, and FICO says one inquiry takes fewer than 5 points for most people and only counts in scores for a year.
Can I refinance only some of my loans?
Usually yes. Many people refinance their private loans and keep federal loans federal, so they get a lower rate where it costs nothing and keep federal protections where they matter.
Can I refinance student loans more than once?
Usually yes, if a lender approves you. Each refinance is a new loan with new terms, so check fees and the new term each time.
What credit score do I need to refinance?
Each lender sets its own rules, and the best rates generally go to borrowers with higher scores and steady income. Many lenders also allow a cosigner if your own credit isn't enough.
