8 Best Lenders to Refinance Student Loans With a Co-Signer of April 2021

Refinancing with a co-signer benefits the borrower, but have a plan to release that person from your loan.

Many or all of the products featured here are from our partners who compensate us. This may influence which products we write about and where and how the product appears on a page. However, this does not influence our evaluations. Our opinions are our own. Here is a list of our partners and here's how we make money.

Refinancing student loans with a co-signer can help you get a lower interest rate or meet a lender’s eligibility criteria, if you can’t on your own. But if you don’t repay the loan, your co-signer is responsible for it; they should be OK with that before helping you.

To ease their worries, have a plan to remove the co-signer from the loan in the future.

The simplest option is to refinance again without the co-signer whenever you can qualify. But if you can’t get a better deal at that point, having a lender that offers co-signer release — not all of them do — can protect you both. Here are lenders with this feature, plus more information about refinancing with a co-signer.

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.

FIXED APR Fixed rate options consist of a range from 3.00% per year to 5.00% per year for a 5-year term, 3.60% per year to 5.30% per year for a 7-year term, 4.10% per year to 5.60% per year for a 10-year term, 4.50% per year to 5.65% per year for a 15-year term, or 4.60% per year to 6.20% per year for a 20-year term, with no origination fees. The fixed interest rate will apply until the loan is paid in full (whether before or after default, and whether before or after the scheduled maturity date of the loan). The monthly payment for a sample $10,000 loan at a range of 3.75% per year to 5.80% per year for a 5-year term would be from $183.04 to $192.40. The monthly payment for a sample $10,000 loan at a range of 5.14% per year to 6.25% per year for a 7-year term would be from $142.00 to $147.29. The monthly payment for a sample $10,000 loan at a range of 5.24% per year to 6.65% per year for a 10-year term would be from $107.24 to $114.31. The monthly payment for a sample $10,000 loan at a range of 5.30% per year to 7.05% per year for a 15-year term would be from $80.65 to $90.16. The monthly payment for a sample $10,000 loan at a range of 5.61% per year to 7.27% per year for a 20-year term would be from $69.41 to $79.16. However, if the borrower chooses to make monthly payments automatically by electronic funds transfer (EFT) from a bank account, the fixed rate will decrease by 0.25%, and will increase back up to the regular fixed interest rate described in the preceding paragraph if the borrower stops making (or we stop accepting) monthly payments automatically by EFT from the designated borrower’s bank account. VARIABLE APR Variable rate options consist of a range from 1.99% per year to 6.05% per year for a 5-year term, 3.75% per year to 6.10% per year for a 7-year term, 4.00% per year to 6.15% per year for a 10-year term, 4.25% per year to 6.40% per year for a 15-year term, or 4.50% per year to 6.65% per year for a 20-year term, with no origination fees. APR is subject to increase after consummation. The variable interest rate will change on the first day of every month (“Change Date”) if the Current Index changes. The variable interest rates are based on a Current Index, which is the 1-month London Interbank Offered Rate (LIBOR) (currency in US dollars), as published on The Wall Street Journal’s website. The variable interest rates and Annual Percentage Rate (APR) will increase or decrease when the 1-month LIBOR index changes. The variable interest rates are calculated by adding a margin ranging from 0.98% to 3.80% for the 5-year term loan, 2.35% to 3.85% for the 7-year term loan, 2.40% to 3.90% for the 10-year term loan, 2.65% to 4.15% for the 15-year term loan, and 2.90% to 4.40% for the 20-year term loan, respectively, to the 1-month LIBOR index published on the 25th day of each month immediately preceding each “Change Date,” as defined above, rounded to two decimal places, with no origination fees. If the 25th day of the month is not a business day or is a US federal holiday, the reference date will be the most recent date preceding the 25th day of the month that is a business day. The monthly payment for a sample $10,000 loan at a range of 3.49% per year to 6.31% per year for a 5-year term would be from $181.87 to $194.77. The monthly payment for a sample $10,000 loan at a range of 4.86% per year to 6.36% per year for a 7-year term would be from $140.68 to $147.82. The monthly payment for a sample $10,000 loan at a range of 4.91% per year to 6.41% per year for a 10-year term would be from $105.63 to $113.09. The monthly payment for a sample $10,000 loan at a range of 5.16% per year to 6.66% per year for a 15-year term would be from $79.92 to $87.99. The monthly payment for a sample $10,000 loan at a range of 5.41% per year to 6.91% per year for a 20-year term would be from $68.28 to $76.99. However, if the borrower chooses to make monthly payments automatically by electronic funds transfer (EFT) from a bank account, the variable rate will decrease by 0.25%, and will increase back up to the regular variable interest rate described in the preceding paragraph if the borrower stops making (or we stop accepting) monthly payments automatically by EFT from the designated borrower’s bank account.

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? Most undergraduate private student loans require a co-signer. 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 4%, and you’d be able to release your co-signer after 36 months of payments. The next-best offer is 5% — 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.
