What Credit Score Do You Need to Refinance Student Loans?
Here is the short answer: there is no single legal minimum, but refinancing student loans into a private loan usually takes a credit score around 650. Many lenders want the upper 600s or higher, and some require 680 or more.
Refinancing asks for stronger credit than the federal loans you started with. Federal loans (except PLUS) come with no credit check at all. A refinance is a brand new private loan, so a private lender is now taking the risk, and it prices that risk off your credit.
Two of the biggest names make the floor concrete. Earnest and SoFi both set a 650 minimum to apply. Meeting that floor gets you approved. The best advertised rates are a different matter: those go to scores of 700 and up, paired with steady income.
Refinance Approval by Credit Score
Here is how the ranges tend to line up when you refinance.
| Credit score | What to expect when you refinance |
|---|---|
| 700 and up | Best pricing and the widest choice of lenders. |
| 680 to 699 | Approved by most lenders at solid rates. |
| 650 to 679 | Meets the typical floor. SoFi and Earnest start here. |
| Below 650 | Approval usually needs a creditworthy cosigner. |
A quick honesty note before you go further: refinancing federal loans with a private lender means giving up federal protections for good, including income-driven repayment, forgiveness programs, and deferment. If there is any chance you will need those, think twice.
What Lenders Really Score
Your credit score is not one mysterious number. It is built from five factors, and the two biggest are the two you can move fastest. Payment history and amounts owed together make up roughly two thirds of a FICO score, and amounts owed is mostly your credit card utilization, which you can lower in a single billing cycle.
That is why the smartest thing you can do before a refinance is pull your card balances down and fix any reporting errors. Both feed straight into the score the lender pulls.
Beyond the Score
Even a strong score does not close a refinance by itself. Lenders also weigh:
- Stable employment and income. They want proof you can carry the new payment. A steady job history helps.
- Debt-to-income ratio. Your monthly debts divided by your monthly income. Lower is better, and a high ratio can sink an otherwise good file.
- A completed degree. Many lenders prefer, and some require, that you finished the program you borrowed for.
- A cosigner, if you need one. A creditworthy cosigner can bridge a thin file or a score below the floor, and often lowers the rate.

How to Improve Your Score Before You Refinance
You do not need a perfect score. You need to cross into the next tier, because rates move in steps.
- Lower your card utilization. Getting balances under 30 percent of their limits, and ideally under 10 percent, is the quickest win. Amounts owed is about 30 percent of your score.
- Fix report errors. One in five reports carries a mistake. Removing a wrong late payment or a paid collection can move your score fast.
- Keep paying on time. Payment history is 35 percent of the score. A clean recent stretch matters most.
- Hold off on new accounts. Fresh inquiries and new balances ding your score and lower your average account age right when a lender is looking.
A realistic 90-day improvement from these moves is 30 to 60 points. That is often enough to jump from one rate tier to the next, which is exactly where your refinance APR starts dropping.
The Bottom Line
You can refinance student loans with a score around 650, but the loan only pays off if the new rate beats your old one, and the best rates start at 700 and up. Weigh the federal protections you would lose before you refinance a federal loan.
Spend a few weeks pulling down card balances and clearing errors first. A 30 to 60 point move can drop your rate a full tier. Download Credit Booster AI on iOS and Android to see your reports, catch what is holding your score back, and fix it before you apply.

Frequently Asked Questions
What credit score do you need to refinance student loans?
There is no single legal minimum, but refinancing into a private loan usually takes a score around 650. Many lenders want the upper 600s or higher, and some require 680 or more. Earnest and SoFi both set a 650 floor, while the best rates go to scores of 700 and up.
Can I refinance student loans with a cosigner?
Yes. A creditworthy cosigner can bridge a thin credit file or a score below the lender’s floor, and often lowers your rate. Many lenders offer a cosigner release after a set number of on-time payments, so the cosigner is not tied to the loan forever.
What are the minimum credit scores at SoFi and Earnest?
Both SoFi and Earnest set a minimum around 650 to refinance student loans. Meeting the floor gets you approved, but not the lowest rate. The advertised best rates go to scores in the 700s and up, paired with steady income and a low debt-to-income ratio.
Should I refinance federal student loans?
Be careful. Refinancing federal loans with a private lender means giving up federal protections for good: income-driven repayment, forgiveness programs, and deferment. If you may need those safety nets, refinancing can cost you more than it saves. It usually makes the most sense on private loans.
What else do refinance lenders look at besides my score?
Stable employment and income, a low debt-to-income ratio, and often a completed degree. Payment history and how much of your available credit you are using drive most of the score they pull in the first place, so cleaning those up before you apply moves both numbers.

What are the minimum credit scores at SoFi and Earnest?
Both SoFi and Earnest set a minimum around 650 to refinance student loans. Meeting the floor gets you approved. It does not get you the lowest rate. The advertised best rates are reserved for scores in the 700s and up, paired with stable income and a low debt-to-income ratio.
Should I refinance federal student loans?
Be careful. Refinancing federal loans with a private lender means giving up federal protections for good: income-driven repayment, loan forgiveness programs, and generous deferment and forbearance. If you may need those safety nets, refinancing can cost you more than it saves. Refinancing private loans, or federal loans you are certain you will never need those protections on, is where it usually makes sense.
What else do refinance lenders look at besides my score?
Stable employment and income, a low debt-to-income ratio, and often a completed degree. A lender wants to see you can carry the new payment. Payment history and how much of your available credit you are using drive most of the score they pull in the first place, so cleaning those up before you apply moves both numbers at once.
