The credit score needed for refinance depends on the loan type, the lender, and the rate you want. A higher score usually means lower rates, smaller fees, and a smoother approval. A lower score does not always block you, but it can raise the cost.
This guide breaks down the typical credit score needed for refinance across mortgages, auto loans, and student loans. It also covers how to lift your score before you apply.
Why Your Score Matters for Refinancing
Refinancing replaces your old loan with a new one, often at a better rate or term. Lenders pull your credit to decide if you are a safe bet. A strong score signals on-time payments, low balances, and steady credit use.
Even a small score bump can shave hundreds or thousands off the total cost. That is why many borrowers wait a few months and prep their credit before applying.
Mortgage Refinance Score Targets
For a conventional mortgage refinance, lenders typically want a FICO score of 620 or higher. The best rates often go to scores of 740 and up.
FHA streamline refinances may accept scores in the 580 range, while VA loans can be flexible for eligible service members. Jumbo loan refinances usually want 700 or more because the loan amount is larger.
Auto Loan Refinance Score Targets
Auto refinance lenders are often more relaxed than mortgage lenders. Many approve scores in the 600s, and some go lower for borrowers with strong income.
To get the best auto refi rates, aim for a score of 700 or higher. The car's age and mileage also matter, since lenders may not refinance very old vehicles.
Student Loan Refinance Score Targets
Private student loan refinancing tends to be the strictest. Most lenders want a score in the high 600s at minimum, and many prefer 700-plus.
Co-signers can help if your score is on the edge. Just remember that refinancing federal student loans into private ones means you lose federal protections like income-driven repayment.
How to Boost Your Score Before Applying
Pay every bill on time for at least six months. Payment history is the largest factor in your score, so a clean streak can move the needle fast.
Keep credit card balances low, ideally under 30 percent of the limit. Paying twice a month can help your reported balance look small.
A secured card or credit-builder loan can also help thin files. The Self Visa® Credit Card pairs with a Self Credit Builder Account, so on-time payments may report to all three bureaus while you save. Terms and conditions apply.
Other Numbers Lenders Check
Your score is not the only thing lenders look at. Debt-to-income ratio, often called DTI, compares your monthly debt to your income. Most refinance lenders want a DTI under 43 percent, and many prefer 36 percent.
They also check loan-to-value ratio for mortgages and autos. The more equity you have, the easier the approval tends to be. A steady job history of two years or more also helps.
When to Refinance and When to Wait
Refinance when rates drop enough to cover closing costs within a reasonable time. A quick break-even calculation can tell you if it is worth it.
Wait if your score recently dropped or you are about to make a big purchase. Hard inquiries from refinance shopping can ding your score for a short time, so plan ahead.
Tips to Strengthen Your Application
Gather pay stubs, tax returns, and bank statements before you apply. Lenders move faster when paperwork is ready.
Check your credit reports for errors and dispute any you find. Even one wrong late payment can lower your score by 30 to 50 points. Firstcard members can keep tabs on their own credit habits inside the app, which makes prep easier.

Frequently Asked Questions
Can I refinance with a 600 credit score?
It depends on the loan type. Some auto refinance and FHA mortgage refinance options may work in the low 600s, but rates will likely be higher. Lifting your score above 660 can open more choices and save money over time.
Will refinancing hurt my credit score?
A refinance triggers a hard inquiry, which can drop your score by a few points for a short time. Closing the old loan and opening a new one also resets the account age. Most borrowers see scores recover within a few months of on-time payments.
How long should I wait between refinances?
Most lenders want at least six months of payments on the current loan before you refinance again. Mortgage lenders may require a longer seasoning period. Refinancing too often can also rack up closing costs that cancel out the savings.
Do all three bureau scores matter for refinance?
Mortgage lenders often pull all three bureau scores and use the middle one. Auto and student lenders may use only one or two. Keeping reports clean at all three bureaus is the safer plan.
