Student Loans Denied With a Cosigner? Here's What To Do Next

A cosigner can often strengthen your private student loan application and make it easier to qualify. More than 90% of undergraduate borrowers who found a loan on Credible between January and July 2026 had a cosigner. Still, having a cosigner doesn’t guarantee approval. 

If your application is denied, you may need to address an issue with your finances or your cosigner’s financial profile before reapplying.

Why was your student loan denied?

A student loan application can be denied for several reasons, even if you apply with a cosigner. Common issues include poor credit, limited credit history, too much existing debt, or not meeting the lender’s eligibility requirements.

Your cosigner’s finances can be a major factor. For example, a lender may deny the application if your cosigner has a high debt-to-income (DTI) ratio, meaning too much of their monthly income already goes toward debt payments.

“They may already have a big mortgage, car loans, or credit cards," explains Jack Wang, a college financial aid adviser. 

A cosigner’s employment history may also affect approval. Lenders may be more cautious if a cosigner has an inconsistent work history because job loss is a common reason borrowers fall behind on student loan payments.

The denial may also have nothing to do with your cosigner. You could be turned down if you don’t meet the lender’s requirements for citizenship or residency, age, enrollment status, or attendance at an eligible school or degree program.

What to do after a cosigner denial

If your student loan application with a cosigner is denied, start by finding out why. The lender should explain what contributed to the decision so you know what needs to change before you apply again.

“Carefully review the denial messaging from the lender and understand the reasons for it,” says Steve Winnie, president of Monogram LLC, which operates Abe student loans.

Winnie also recommends reviewing the credit report the lender used to make its decision. Your denial notice should include instructions for getting a copy. Check the report for problems that may have hurt your application, such as late payments, accounts in collections, or incorrect information.

Once you know why you were denied, you can decide what to address before reapplying. That might mean having your cosigner pay down debt to lower their debt-to-income ratio, improve their credit, or correct errors on their credit report. If your cosigner still doesn’t meet the lender’s requirements, you could also consider applying with a different cosigner.

How to find a stronger cosigner

If your cosigner contributed to the denial, applying again with someone who has stronger finances could improve your chances of approval.

Look for a cosigner with good credit, steady income, and relatively little debt. A credit score of 700 or higher may put them in a stronger position, although requirements vary by lender. A lower debt-to-income ratio can also help because it shows the cosigner has enough income to manage their existing debts along with the new loan.

“Look for a creditworthy cosigner who is a U.S. citizen or permanent resident with stable income and a strong credit history — meaning positive payment behavior on multiple accounts for several years,” Winnie says.

You’ll also want someone with a consistent employment history. If a potential cosigner is self-employed, Wang says lenders may want to see at least two years of steady income before considering those earnings.

Can you get a student loan without a cosigner?

Most federal student loans don’t require a credit check or minimum income, so undergraduate borrowers don’t need a cosigner to qualify.

Private student loans are different. Most lenders consider your credit and income, which can make qualifying on your own difficult if you’re still in school and haven’t had much time to build credit or establish a steady income.

“To get a loan without a cosigner, the student must have been working at a good-paying job for at least two years, have no debt, and have an excellent credit score,” explains Mark Kantrowitz, a nationally recognized expert on student financial aid. 

Some private lenders also offer loans that rely less heavily on traditional credit criteria. For example, Ascent offers an outcomes-based loan that considers factors such as your GPA, degree program, and academic performance rather than requiring a minimum credit score or income.

How to improve your approval odds

If you were denied a student loan, strengthening your finances or changing how you apply could improve your chances the next time. Consider these steps:

• Build your credit: Pay bills on time, bring past-due accounts current, and pay down credit card balances. If you have little or no credit history, responsibly using a credit card or another account that reports to the credit bureaus can help you build credit over time.
• Find a stronger cosigner: Look for someone with good credit, stable income, and relatively little debt. A financially stronger cosigner can improve your chances of qualifying and may help you get a lower interest rate.
• Reduce your debts: Paying down debts, such as credit card balances or a car loan, reduces the amount of your income that goes toward monthly debt payments. Increasing your income can also lower your DTI. A DTI of 36% or lower is ideal.
• Shop around for your lender: Credit, income, and other eligibility requirements vary by lender. Prequalifying with several lenders using a tool like Credible can help you compare potential rates and eligibility without affecting your credit score.
