Whether you're starting college or pursuing an advanced degree, figuring out how to pay tuition is often one of the biggest challenges.
If federal student loans aren't enough to cover your costs, private student loans may help fill the gap. And if your credit history is limited or less than ideal, applying with a co-signer can improve your chances of approval and help you qualify for better rates.
A co-signer with strong credit and stable finances reduces the lender's risk because they're equally responsible for repaying the loan if you can't.
Below, we highlight some of the best student loan lenders that allow borrowers to apply with a co-signer. See our methodology for more information on how we made our selections.

Actual rate and available repayment terms will vary based on your financial profile. Our lowest rates are only available for the most credit qualified existing cosigned loan borrowers who receive the 0.25% Loyalty discount and requires selection of our shortest term offered, full principal and interest payment while in school, and enrollment in our 0.25% Auto Pay discount. Enrolling in Auto Pay is not required as a condition for approval. Interest rates are subject to change.
Residents of Hawaii must request a loan of at least $1,501.
You can take advantage of the Auto Pay interest rate reduction by setting up and maintaining active and automatic ACH withdrawal of your loan payment from a checking or savings account. The interest rate reduction for Auto Pay will be available only while your loan is enrolled in Auto Pay. Interest rate incentives for utilizing Auto Pay may not be combined with certain private student loan repayment programs that also offer an interest rate reduction. It is important to note that the 0.25% Auto Pay discount is not available when loan payments are deferred during the interim period as a result of selecting the deferred repayment option.
To be eligible for the Loyalty Discount, applicants must have previously obtained an Earnest Private Student Loan and apply using the same email address associated with that loan. Only one Loyalty Discount may be applied per eligible Earnest Private Student Loan. Not all applicants may qualify. This offer cannot be combined with Earnest's Rate Match program. Earnest may modify or discontinue this offer at any time and without notice, however, once a Loyalty Discount is earned, it will not be taken away.
Nine-month grace period is not available for borrowers who choose our Principal and Interest Repayment plan while in school.
Earnest clients may skip a payment through a single, one-month forbearance during a 12 month period. Your first request to skip a pay can be made once you've made at least 6 months of consecutive on-time full principal and interest payments, and your loan is in good standing. The interest accrued during the skipped month will result in an increase in your remaining minimum payment. The final payoff date on your loan will be extended by the length of the skipped payment periods. Any unpaid accrued interest may capitalize (added to the principal balance) at the end of the forbearance period by adding unpaid accrued interest to the outstanding principal as permitted by law and the terms of the loan agreement. Please note that skipping a payment is not guaranteed and is at Earnest's discretion. Your monthly payment and total loan cost may increase as a result of postponing your payment and extending your term.
Best for co-signer release: Edly
Who's this for? Edly offers a co-signer release after making just six consecutive monthly payments — the shortest release terms we found. A co-signer release means that your co-signer will no longer be on the hook for your loan. Many other lenders require you to make at least 12 or more consecutive payments before your co-signer can be released. Other lenders don't offer a co-signer release at all.
Standout benefits: Edly offers deferment and forbearance options to help you pause payments if you lose your job or your income falls below a certain amount.

FAQs
What's a co-signer?
A co-signer is someone who agrees to assume responsibility for a borrower's debt, like a loan payment, if the borrower defaults and is unable to make payments. Co-signers can help subprime borrowers get approved for a loan or other form of debt and get better repayment terms.
What's a co-signer release?
A co-signer release allows a co-signer to be removed from the responsibility of repaying a loan if the borrower defaults. Essentially, it lets the co-signer off the hook legally and financially. For student loans, co-signer releases can happen after making a certain number of consecutive, on-time payments, assuming the lender offers co-signer releases.
Does co-signing a student loan hurt your credit?
Co-signing can hurt your credit if the borrower is unable to make payments on time or if they default on the loan. It can also hurt your credit if you yourself are unable to make the loan payments when the responsibility falls on you to start making payments.

- Fees, including application and origination fees or a prepayment penalty
- Loan terms available
- Repayment options
- Whether borrowers can access hardship relief, including deferment and forbearance

APRs for variable-rate loans may increase after origination if the SOFR index increases. Autopay Discount: The SoFi 0.25% autopay interest rate reduction requires you to agree to make monthly payments as outlined in your loan agreement by an automatic monthly deduction from a savings or checking account. This benefit will discontinue and be lost for periods in which you do not pay by automatic deduction from a savings or checking account. When the autopay interest rate deduction is added or removed, the next time the loan is re-amortized (quarterly for fixed rate loans; monthly for variable rate loans),the principal balance of your loan will be spread over the remaining loan term, and your monthly payment amount will change. This benefit is suspended during periods of deferment, grace period, or forbearance. Autopay is not required to receive a loan from SoFi.
