DisclaimerAPR, projected monthly payments, and total cost of loan examples are based on a $10,000 loan disbursed in one disbursement with either 5–year, 10–year, 15–year or 20–year repayment. APR’s provided include a 0.25 percent interest rate reduction for authorizing our loan servicer to automatically deduct your payments each month from your bank account. The interest rate reduction for authorizing our servicer to automatically deduct monthly payments from a savings or checking account will not reduce the monthly payment, but will reduce the monthly finance charge, resulting in a lower total cost of loan. Variable APR rates may increase or decrease depending on fluctuations in the London Interbank Offered Rate (LIBOR) index. Monthly interest rate accrual is based on the published One–Month London Interbank Offered Rate ("LIBOR") as of the last business day of the previous month plus your applicable margin.

DisclaimerBrazos Refinance Loan fixed rates from 4.40% APR to 7.25% APR (with Auto-Pay Discount). Variable rates from 4.99% APR to 8.79% APR (with Auto-Pay Discount). Interest rates on Brazos loans are capped at 9.90%. Lowest variable rate of 4.99% APR assumes a current Thirty-day Average Secured Overnight Financing Rate (SOFR) of % plus a 2.03% margin minus the 0.25% Auto-Pay Discount. Not all borrowers receive the lowest rate. If approved for a Brazos loan, the fixed or variable interest rate offered will depend on your creditworthiness, the term of the loan and other factors, and will be within the ranges of rates listed above. For the Brazos variable rate loan, the Thirty-day Average SOFR index will adjust monthly and the loan payment will be re-amortized and may change monthly. APRs for variable rate loans may increase after origination if the SOFR index increases. Auto-Pay Discount. The interest rate in effect will be reduced by 0.25% if either the borrower or the cosigner authorizes automated (ACH) payments from any bank account. This ACH interest rate reduction, referred to as the Auto-Pay Discount, applies only when full principal and interest payments are automatically drafted from a bank account. This interest rate reduction will not continue to apply during periods of approved forbearance or deferment. The Auto-Pay Discount will terminate if the automatic bank account payments discontinue or there are any three instances of insufficient funds at any time during the term of the loan. A borrower may requalify upon reauthorization of automatic payments from a valid bank account. 2. Refinancing Federal Loans. While refinancing government loans as well as private loans may help many borrowers, federal loans have certain benefits that can help borrowers who experience financial distress. Private loans typically don’t have the same benefits. Everyone’s situation is different, so think carefully about refinancing your government loans and talk about it with a trusted advisor. 3. Credit Review and Approval. If you choose to apply for a Brazos Student Loan, Brazos Parent Loan, or Brazos Refinance Loan and continue your application past the pre-credit eligibility stage, we will request your full credit report from one or more consumer reporting agencies, which is considered a hard credit inquiry. Hard credit inquiries (or hard credit pulls) are required for Brazos to be able to issue you a Brazos loan. In addition to requiring your explicit permission, these credit pulls may impact your credit score. The initial credit review is based on review of all the information you and your cosigner (if applicable) provide during the application process and the information obtained from your credit report(s). If you pass the initial credit review, you will need to provide acceptable documentation such as your income verification before the final loan approval. 4. Brazos Education Lending Corporation (Brazos) is a part of a group of several non-affiliated nonprofit companies that are all managed by The Brazos Higher Education Service Corporation, Inc. and are commonly referred to as the Brazos Managed Companies. The first of the Brazos Managed Companies was organized in 1975 in Waco, Texas, as a secondary market for student loans. Since that time, the Brazos Managed Companies have, on a combined basis, served an estimated 2 million student borrowers and have helped fund an estimated $30 billion in student loans.

Can you refinance student loans with a co-signer?

Most lenders will let you refinance student loans with a co-signer, with Earnest being a notable exception. Here are some reasons you may want to refinance with a co-signer:

  • Your finances aren’t strong enough. Student loan refinance eligibility varies by lender, but you’ll typically need a credit score in at least the high 600s, a debt-to-income ratio below 50% and steady income. If you can’t meet these requirements, applying with a co-signer who does may help you qualify.

  • You can’t qualify for a nonfinancial reason. A co-signer might help depending on the reason. For example, if you’re an international student, you may be able to refinance with an eligible co-signer. In other instances — like refinancing without a degree — adding a co-signer wouldn’t make a difference.

  • You can get a better interest rate. A loan with more than one borrower is less risky for the lender, which means it may offer you a better rate. Plus, interest rates on refinance loans are credit-based in general. So even if you can qualify on your own, adding a co-signer with a stronger financial profile could improve a lender’s offer to you.

Should you refinance student loans with a co-signer?

Ask the following to decide if co-signing is the right move:

  • Can the co-signer afford the loan? Co-signing a student loan makes that person responsible for it. While they may not plan to repay the loan, they’ll have to if you don’t. The debt will also go on their credit report, meaning missed payments will hurt their credit score and the loan amount could affect their ability to do things like take out or refinance other debts.

  • Are they already on the hook for other debt? Most undergraduate private student loans prompt borrowers to add a co-signer early on in the application process. If you’re refinancing one of these loans, asking that person to co-sign again won’t change their responsibility. But it could reduce their risk: By helping you get a lower payment, you may be less likely to run into trouble and able to pay the loan off faster.

  • Is there a plan for release? You can refinance again to remove the co-signer; this can make sense if your financial situation improves. If that won’t happen soon, make sure the lender offers co-signer release — some, like SoFi, don’t — and you both understand the requirements. This will likely include making a set number of consecutive, full, on-time payments and meeting the original loan’s underwriting criteria.

How to refinance student loans with a co-signer

When you apply to refinance a student loan on a lender’s website, you’ll likely be asked if you want to include a co-signer. You can then add that person’s information accordingly.

But before doing that, pre-qualify with multiple lenders — with and without a co-signer. This will let you see potential interest rates for both scenarios without affecting your credit.

Your goal should be to get the best rate possible. But if you refinance with a co-signer, you’ll have to weigh the risk that person faces versus the reward of a lower rate. For example, say the lowest rate you’re offered is 6%, and you’d be able to release your co-signer after 36 months of payments. The next-best offer is 7% — but release is available after 12 months.

A student loan refinance calculator can help you understand how much that one percentage point could save you. It will be up to you and your co-signer to determine whether that amount is worth more than a quicker path to release.
