If your income or credit score falls short of lender requirements, getting a personal loan can feel impossible. A cosigner strengthens your chances of approval, including getting lower interest rates and helping you qualify for a larger amount.

But cosigning comes with serious shared responsibility. Missed payments hurt both of your credit scores. Should you default on your loan, your cosigner will be legally on the line for the entire balance.

Understanding the role of a cosigner

A cosigner helps your loan application by agreeing to repay the loan if you don’t. Lenders look at their credit score and income along with yours, which can make approval more likely. You’ll have full access to the funds, but the cosigner shares equal responsibility for paying back the loan; if you miss payments, it affects their credit too.

You might need a cosigner if you:

  • Have a low or unstable income
  • Have limited credit or no credit history
  • Work gig or freelance jobs
  • Have a high debt-to-income (DTI) ratio
  • Don’t meet the lender’s minimum age requirement

Benefits of a cosigner

A cosigner can be beneficial during the application process because they strengthen your application and can improve your chances of getting approved.

Sometimes lenders offer borrowers who find a cosigner better terms, such as lower interest rates, longer repayment terms or larger loan amounts. Adding a cosigner can help you access the funds you need more quickly so that you can start building a positive credit history through on-time payments.

“Having a cosigner could lower your interest rate in some cases,” Trevor Smith, a corporate branch manager at Wasatch Peaks Credit Union in Ogden, Utah, told us. “Many institutions will use the highest score of the two borrowers to determine which rate is given. Having a cosigner may also help to qualify for higher loan amounts. In a lot of cases, income can be combined, which makes it more likely to get higher loan amounts.”

Be sure to make timely payments since this will positively impact both your credit and that of your cosigner. Late and missed payments, however, will have a negative impact on both your credit scores. This not only damages your finances but could also damage your relationship.

Applying for a personal loan with a cosigner

Applying for a personal loan with a cosigner involves a few extra steps, but it can help you qualify for better terms. Here’s what to do:

1. Find lenders that allow cosigners

Not all lenders accept cosigners, so start by narrowing your options to those that do.

2. Check eligibility requirements

Review minimum credit scores, income levels and any other conditions before applying.

3. Gather required documents

You’ll need to provide personal and financial information for both you and your cosigner. Before applying, check that your credit score and DTI ratio meet the lender’s requirements. Many lenders look for a minimum credit score of 580 and a DTI ratio below 36%. If you don’t meet these standards, a cosigner who does could improve your chances of approval.

Commonly required personal details include:

  • Social Security number
  • Date of birth
  • Phone number
  • Physical address
  • Employment status and employer name
  • Gross monthly income and source
  • Monthly rent or mortgage payment amount

4. Submit the loan application

Fill out the application with all required documents. The lender will run a hard credit check on both you and your cosigner.

5. Review the loan terms

If you’re approved, review the interest rate, loan term and repayment obligations. Your cosigner is equally liable if you default, so make sure both parties understand the responsibilities.

Most lenders approve applications within five business days. You may receive funds as soon as the next business day.

Responsibilities and risks for cosigners

The biggest risk for cosigners is that the primary borrower stops making payments, and they have to assume the loan themselves. Unfortunately, cosigners have the same responsibilities for paying off a loan as primary borrowers, but they don’t receive any loan funding.

If the primary borrower has late or missing payments, it can negatively impact both the cosigner's and the primary borrower's credit.

Leslie Tayne, the founder of Tayne Law Group in Melville, New York, explained: “The cosigner could also be sued or have their wages garnished if the loan goes into default or into collections. Legal implications, such as wage garnishment, can have serious negative effects on a credit profile and can take years to recover from.”

If you’re thinking about becoming a cosigner, consider how trustworthy the primary borrower is. You may want to ask them to show you their budget; that way, you can confirm that they can afford the loan payments.

Also, ensure you can log in to the lender's website to view the loan payments. You may not be notified by the lender that payments have been missed until it has negatively affected your credit.

Finally, be prepared to step in and make payments if needed. You are guaranteeing the loan, so you’re legally responsible for it. Make sure that your day-to-day finances won’t be affected if you wind up having to make payments for the primary borrower.

Comparing personal loan options with a cosigner

When comparing personal loans, the borrower and the cosigner should discuss the following:

  • Loan amount: Borrow only what you need. A larger loan means higher monthly payments and more interest over time.
  • Interest rate: Some lenders base your rate on the higher of the two credit scores, which could lower your interest rate. The rate you receive plays a major role in the total cost of the loan.
  • Loan term: A longer loan term lowers monthly payments but increases total interest costs. Make sure the timeline works for both you and your cosigner.
  • Fees: Watch for origination fees and prepayment penalties. Origination fees typically range from 1% to 10% of the loan amount and may be deducted from the loan or paid upfront.

FAQ

Can I get approved for a personal loan with a cosigner?

Yes, getting a cosigner can help you get approved if you don’t qualify on your own. A cosigner adds their income and credit history to your application, which makes you less risky in the eyes of the lender. This can improve your chances of approval, especially if your cosigner has strong credit and a low debt-to-income ratio.

Do I have a better chance of getting a loan with a cosigner?

Yes, applying with a cosigner can improve both your chances of approval and the terms you’re offered, especially if the lender uses the higher of the two credit scores or combines incomes when reviewing the application. A cosigner can also help you qualify for a larger loan, a longer repayment term or a lower interest rate than you’d get on your own.

How does cosigning affect my credit score?

Cosigning affects your credit the same way that signing up for a loan does. The loan is on your credit report, so your score can go up or down depending on the payment history. Consistent payments can help your credit, but missed ones will hurt it, even if you’re not the one making them.

Why might a lender require a cosigner?

A lender will require a cosigner when the primary borrower doesn't qualify for the loan without one. It could be that their credit score isn’t high enough or that they don’t earn enough money to comfortably make payments.
