Cosigning a Loan: How It Affects Your Credit Score
Understand the risks and responsibilities of cosigning a loan, how it impacts your credit score, and what to consider before agreeing to cosign.
Key Takeaways
- You're 100% responsible if the borrower doesn't pay
- The loan appears on your credit report as your debt
- Late payments hurt your credit, not just theirs
- It's very difficult to remove yourself as cosigner
- Your DTI ratio is affected, limiting your own borrowing
What Cosigning Actually Means
When you cosign a loan, you're promising to pay the entire debt if the primary borrower doesn't. You're not just vouching for someone—you're taking on full legal and financial responsibility for the loan.
Cosigner Responsibilities
- Liability: 100% of loan amount
- Credit reporting: Appears on your report
- Collection calls: Creditors can pursue you
- Legal action: Can be sued for the debt
This Is Your Debt Too
From the lender's perspective, there's no difference between you and the primary borrower. If they don't pay, you owe the full amount. The lender can come after whichever of you is easier to collect from.
How Cosigning Affects Your Credit
Immediate Effects
- Hard inquiry: The loan application appears as an inquiry on your credit report
- New account: The loan is added to your credit report as your debt
- Debt-to-income: The full loan amount counts against your DTI ratio
Ongoing Effects
- Payment history: Every payment (or missed payment) is reported on your credit
- Utilization: For credit cards, the balance affects your utilization
- Borrowing capacity: The debt limits what you can borrow for yourself
If the Borrower Pays on Time
- Positive payment history added to your report
- Can help build credit for both parties
- Still affects your DTI until paid off
If the Borrower Misses Payments
- Late payments appear on YOUR credit report
- Your credit score drops—potentially significantly
- Creditors contact you for payment
- Can go to collections on your credit report
- Creditors can sue you for the balance
The Real Risks of Cosigning

- Affects your ability to borrow
- Could be sued for the debt
- May not know about problems until too late
Statistics Are Not in Your Favor
Studies suggest that 38% of cosigners end up paying some or all of the loan themselves. 28% report damaged credit from the cosigned loan. 26% say it damaged their relationship with the borrower.
Before You Agree to Cosign
Understand Why They Need a Cosigner
If they were denied credit alone, there's a reason. Understand their financial situation—income, existing debt, employment stability, payment history.
Consider the Full Loan Amount
Ask yourself: can I afford to pay this entire loan if needed? If the answer is no, don't cosign. Hope is not a repayment plan.
Check for Cosigner Release Options
Some loans allow cosigner release after 12-24 months of on-time payments. Ask if this is available and get it in writing.
Set Up Payment Monitoring
Ask to receive account statements or set up alerts. You need to know immediately if payments are missed—before it hits your credit report.
Have an Exit Strategy
Discuss what happens if they can't pay. Will they refinance? Will you take over payments? Having a plan prevents surprises.
Alternatives to Cosigning
- Gift the down payment: Help with upfront costs instead of ongoing liability
- Add as authorized user: Helps them build credit without loan liability
- Help them build credit first: Secured card for 6-12 months, then try again
- Smaller loan: Maybe they can qualify for a smaller amount alone
