Best Co-Signed or Joint Personal Loans in 2025

What’s the difference between a co-signer and a co-borrower?

Though some people use the terms “co-signer” and “co-borrower” interchangeably, they have distinct meanings. Co-signers and co-borrowers have different responsibilities for repaying a personal loan and accessing funds.

Co-signer: A co-signer vouches for someone else’s loan application and agrees to repay it if the borrower doesn’t. The co-signer can’t access the loan proceeds, nor can they see information about the loan, like how much you’ve repaid or if you missed a payment, unless they request that information be sent to them.

Co-borrower: A co-borrower is a partner applicant on a joint personal loan and shares responsibility for repayment. This person has equal access to loan funds and payment information.

Lenders more commonly offer joint personal loans rather than co-signed personal loans. If you’re looking to boost your odds of personal loan approval, applying with a co-borrower who has better credit or a higher income might be the way to go.

Here are lenders that offer either co-sign or joint personal loans (or both):

How to get a personal loan with a co-signer or co-borrower

Here are the steps to get a personal loan with a co-applicant.

1. Check both of your credit and financial information. The lender will weigh both applicants’ credit scores, incomes and debt-to-income ratios. Familiarize yourself with this information to set expectations before applying.

2. Compare lenders. Some lenders have specific requirements for joint loan applicants, while a co-signer is typically expected to have better credit and income than the primary borrower. Compare personal loan requirements and features from multiple lenders and select a few that meet your needs.  

3. Pre-qualify and add a co-applicant. Pre-qualify with multiple lenders to compare estimated rates and terms. The pre-qualification process can be different for joint and co-signed loans. Joint loan applicants can sometimes pre-qualify together to preview potential rates and loan amounts. Applicants who want to add a co-signer may need to pre-qualify by themselves and, depending on the results, the lender may provide a co-signed loan option.

4. Submit your application and get funded. Once you select your preferred lender and submit an application, the lender will likely do a hard credit check on you and your co-applicant. If approved, expect to receive your funds within a few days.

When is a co-signer or co-borrower a good idea?

Lenders use information like your credit and income to decide whether you qualify and what your loan amount and annual percentage rate should be. Adding someone with better credit, higher income and low debt to support your application gives a lender confidence that the loan will be repaid.

A co-signer or co-borrower can help if:

• You have bad credit. There are personal loans for bad credit, but few lenders approve applicants with credit scores below 600. If that’s you, a co-applicant with better credit could increase your approval odds.

• You want a larger loan. Lenders offer the largest loans to well-qualified applicants, so including a co-applicant could increase the size of your loan.

• You need a lower rate. Adding someone to the application could get you a lower rate, meaning lower monthly payments and a less expensive loan overall.

How much a co-signer or co-borrower helps depends on factors such as:

• The co-applicant’s credit score.

• The co-applicant’s credit history.

• The co-applicant’s debt-to-income ratio.

• The lender’s underwriting criteria.

It’s important for you and your co-applicant to understand the risks of co-signing or co-borrowing before submitting an application. These can include:
