Should I Refinance My Student Loans?
Refinancing can save thousands in interest, or strip away federal protections you may need. Here is how to tell which side you are on, with a calculator that runs your real numbers.
Refinancing can save thousands of dollars in interest, but it is not the right choice for everyone. The biggest factor is whether the interest savings outweigh the federal benefits you may lose. Refinancing turns your loan into a private loan, and that move is permanent. The right answer depends on:
- Loan type (federal versus private)
- Interest rate (yours now versus what you would qualify for)
- Income stability
- Career plans
- Forgiveness eligibility
Refinancing often makes sense if
- ✓ You have stable income
- ✓ You have private loans
- ✓ You qualify for a lower rate
- ✓ You are not pursuing forgiveness
Refinancing may not make sense if
- ✕ You may qualify for PSLF
- ✕ You rely on income-driven repayment
- ✕ You need federal protections
- ✕ Your income is uncertain
What does student loan refinancing actually do?
Refinancing replaces your existing loan with a new loan that may have a different interest rate, payment, or repayment term. A private lender pays off your old loans and issues you a single new one. If your old loans were federal, they are now private, and that is the catch: the new loan does not carry any of the federal protections the old ones did.

The savings come almost entirely from the size of the rate cut. Here is the lifetime interest on a $50,000 balance paid over a 10-year term as the rate drops from 8%, and what each cut saves:
| Rate change | New monthly payment | Lifetime interest | Interest saved |
|---|---|---|---|
| 8% (current) | ~$607 | ~$22,800 | $0 |
| 8% → 7% | ~$581 | ~$19,700 | ~$3,100 |
| 8% → 6% | ~$555 | ~$16,600 | ~$6,200 |
| 8% → 5% | ~$530 | ~$13,600 | ~$9,200 |
| 8% → 4% | ~$506 | ~$10,700 | ~$12,000 |
The pattern is simple: each percentage point off a $50,000 balance is worth roughly $3,000 over a 10-year payoff, and the savings scale with your balance.
When refinancing makes sense
Refinancing generally makes sense when you can meaningfully reduce your interest rate without giving up benefits you need. Lean toward refinancing if most of these are true:
✓ Your loans are private
There are no federal protections to lose, so a lower rate is almost pure upside.
✓ Your income is stable
You can comfortably cover the payment without needing federal forbearance.
✓ Your rate is high
You are paying 7%+ and qualify for something at least ~1 point lower.
✓ Your credit is strong
A 740+ score unlocks the lowest advertised rates and the biggest savings.
✓ You do not need federal programs
You are not pursuing PSLF or relying on income-driven repayment.
When refinancing does NOT make sense
Refinancing can be a mistake if you are giving up valuable federal loan protections. When you refinance a federal loan into a private one, here is exactly what you lose, and why each one matters:
| Protection lost | Why it matters |
|---|---|
| PSLF | Forgives your entire remaining federal balance tax-free after 120 qualifying payments in nonprofit or government work. Gone permanently after refinancing. |
| Income-driven repayment | Caps your federal payment at a percentage of discretionary income, so payments fall if your income does. Private loans have no equivalent. |
| Federal forbearance | Lets you pause payments during hardship for up to 12 months at a time. Private lenders offer little or nothing comparable. |
| Federal deferment | Pauses payments for school, unemployment, or military service, sometimes without interest accruing on subsidized loans. |
| Death / disability discharge | Federal loans are forgiven if you die or become permanently disabled. Many private loans are not, leaving the balance to your estate or cosigner. |
Federal loans vs private loans
Refinancing trades federal flexibility for a potentially lower rate. Here is what sits on each side of that trade:
| Feature | Federal loans | Private loans |
|---|---|---|
| PSLF eligibility | Eligible (qualifying employer) | Not eligible |
| Income-driven repayment | Available | Not available |
| Forbearance options | Generous federal options | Limited, lender-dependent |
| Refinancing potential | Fixed federal rate | Can refinance freely for a lower rate |
| Flexibility | High (many safety nets) | Low (rate-focused) |
Real refinance scenarios
The right answer changes completely with loan type and career plans. Here are three borrowers and what they should do:
Teacher: $70,000 federal loans
Do not refinanceIncome $65,000 • all federal
A public-school teacher is a textbook PSLF and income-driven repayment candidate. Refinancing would lock in a slightly lower rate but throw away the chance to have the balance forgiven tax-free, plus the payment relief if income dips. Keep these federal and look into forgiveness first.
Engineer: $45,000 private loans
RefinanceIncome $120,000 • all private
These loans are already private, so there are no federal protections to lose. With a strong income and good credit, dropping from, say, 9% to 5.5% is almost pure savings, several thousand dollars and a faster payoff. This is the clearest yes there is.
Dentist: $300,000 mixed loans
Refinance partIncome $220,000 • federal + private
The smart move is a split. Refinance the private portion now for an easy rate cut, and keep the federal portion federal until PSLF is clearly off the table. With a six-figure balance, even a one-point cut on the refinanced share is worth tens of thousands, so do it on the loans where there is nothing to lose. More for dentists here.
Should you refinance or pay extra?
Sometimes extra payments generate more value than refinancing, and they carry far less risk. They are not mutually exclusive, but here is how the two compare on their own:
| Strategy | Interest savings | Payoff speed | Flexibility |
|---|---|---|---|
| Refinance | Lowers the rate on the whole balance | Faster only if you keep the payment up | Lower (loses federal options) |
| Extra payments | Cuts interest by shrinking the balance | Faster, scales with how much extra | High (keeps all protections) |
| Refinance + extra | The most of any option | Fastest | Lower (still private) |
The takeaway: if you have federal loans and any doubt, start with extra payments, they shrink the debt with zero downside. If your loans are private or you are certain you will not need federal benefits, refinancing to a lower rate and then paying extra on top is the most powerful combination. See what an extra $100 a month does.
What credit score is needed to refinance?
Borrowers with stronger credit profiles typically qualify for better refinance rates. Lenders also weigh income and debt-to-income, but score is the gatekeeper. Rough expectations:
Excellent
740+Qualify for the lowest advertised rates. This is where refinancing pays off most.
Good
700-739Solid rate offers, usually a bit above the best tier. Still often worth it.
Fair
660-699May qualify, but rates may be too close to your current one to bother. A cosigner can help.
Poor
Below 660Likely declined or offered a high rate. Build credit first, or add a strong cosigner.
Biggest student loan refinancing mistakes
Most refinancing regret comes from a handful of avoidable mistakes. Watch for these:
Refinancing before understanding PSLF
The most expensive mistake. Converting federal loans to private is permanent and throws away potential forgiveness.
Extending the repayment term too long
Stretching to 20 years lowers the monthly payment but can increase total interest, even at a lower rate.
Focusing only on the monthly payment
A lower payment can hide a higher lifetime cost. Always check total interest.
Ignoring total interest cost
The monthly number feels good, but the lifetime interest is the real scoreboard.
Not comparing multiple lenders
Rates vary meaningfully between lenders. Checking several pre-qualified offers costs nothing and can save thousands.
Should you refinance right now?
Walk these five questions in order. The first “stop” answer is your answer.
1Are your loans federal?
No → If they are private, you have nothing federal to lose. If the rate is lower, refinance.
Yes → keep going.
2Are you planning to pursue PSLF or forgiveness?
Yes → Do not refinance. You would forfeit forgiveness permanently.
No → keep going.
3Is your income stable?
No → Lean toward keeping federal protections until your income steadies.
Yes → keep going.
4Do you qualify for a meaningfully lower rate?
No → Wait. If the rate is barely lower, it is not worth losing federal options.
Yes → keep going.
5Do you need federal protections (IDR, forbearance) as a safety net?
Yes → Keep your loans federal, or refinance only the private portion.
No → Refinancing is likely a strong move for you.
Bottom line: refinance private loans whenever the rate is lower, and only refinance federal loans once you are certain you will not need forgiveness or federal safety nets.

Should I refinance my student loans?
Refinance if you have stable income, can qualify for a meaningfully lower rate, and are not relying on federal benefits like PSLF or income-driven repayment. Refinancing replaces your loan with a private one, so it makes the most sense for borrowers who already have private loans or who are certain they will pay the debt off themselves. If there is a real chance you will pursue forgiveness, or your income is uncertain, keeping federal loans federal is usually the safer call.
How much can refinancing save?
It depends on your balance and how far the rate drops. On a $50,000 balance paid over 10 years, cutting the rate from 8% to 6% saves about $6,200 in interest, and 8% to 5% saves about $9,200. As a rough rule, each one percentage point off a $50,000 balance is worth roughly $3,000 over a 10-year payoff. Larger balances scale proportionally. Use the calculator on this page to estimate your own number.
Can I refinance federal student loans?
Yes, but only by converting them into a private loan with a private lender. There is no way to lower your federal rate and keep the loans federal. That conversion is the whole tradeoff: you may get a lower rate, but you permanently lose federal benefits like PSLF, income-driven repayment, generous deferment and forbearance, and death and disability discharge. Many borrowers refinance private loans first and leave federal loans federal until they are sure they will not need the protections.
Does refinancing remove PSLF eligibility?
Yes. Refinancing federal loans into a private loan permanently removes eligibility for Public Service Loan Forgiveness and any federal income-driven repayment forgiveness. PSLF can forgive your entire remaining federal balance tax-free after 120 qualifying payments while you work for a qualifying nonprofit or government employer. If there is any real chance you will pursue PSLF, do not refinance the federal portion of your loans.
What credit score is needed to refinance?
Most private lenders want a score in the high 600s to qualify, and 740 or above for the best advertised rates, along with stable income and a manageable debt-to-income ratio. Borrowers with thin credit or variable income may get a higher rate or need a cosigner. Because the entire value of refinancing comes from the rate, it is worth checking pre-qualified rates from several lenders before committing.
Should I refinance or make extra payments?
They are not mutually exclusive, and extra payments are lower-risk. Extra payments shorten your payoff and cut interest without giving up any federal protections, so they are the safer first move, especially on federal loans. Refinancing changes the rate on the whole balance, which can save more on high-rate private loans. The most powerful combination, when you do not need federal benefits, is to refinance to a lower rate and then keep paying extra on top.
Can refinancing lower my monthly payment?
Yes, in two ways. A lower interest rate reduces your payment for the same term, and extending the term lowers the monthly payment further. Be careful with the second one: stretching a loan from 10 years to 20 years can lower the monthly payment while increasing the total interest you pay, even at a lower rate. Always check the lifetime interest, not just the monthly number, which the calculator on this page does for you.
