Don’t cosign unless you can afford to pay the entire loan yourself and are willing to accept that you might have to. About 38% of cosigners end up making payments — this is not a hypothetical risk.

What Happens When You Cosign

Consequence Impact on You
Loan appears on your credit report Increases your debt-to-income ratio
Any late payment damages your credit Even if it’s “their” loan
You’re sued if borrower defaults Lender can come after you for the full amount
Your wages can be garnished Legal judgments allow this
Hurts your ability to borrow The full loan amount counts towards your DTI
Relationship strain Money problems destroy relationships

The Statistics

Cosigning Statistic Number
Cosigners who end up making payments 38%
Cosigners who experienced credit damage 28%
Cosigners who had a damaged relationship 26%
Cosigners who would do it again Under 50%

When Cosigning Might Be Acceptable

Situation Why
Your child’s first auto loan (small amount) Building their credit; you control the outcome
Parent’s student loan (federal, income-driven) Federal protections exist
You can pay the full amount without noticing Minimal financial risk
Borrower has income but no credit history Temporary need (immigrant, young adult)
You set up payment monitoring Catch problems before they become disasters

When to Say No

Situation Why
You can’t afford the loan yourself If they default, you’re in trouble too
The borrower has a history of late payments Past behavior predicts future behavior
It’s a large loan (car, mortgage) Too much risk
You’d resent them if you had to pay Don’t cosign with strings attached
Anyone pressures you into it Financial pressure is a red flag
You’re planning to buy a home or car The cosigned debt hurts your DTI

Alternatives to Cosigning

Alternative How It Works
Gift them part of the money No strings, no liability
Help them build credit first Authorized user on your card, secured credit card
Help them find lenders that work with thin credit files Credit unions, community banks
Co-borrow instead (joint loan) You have legal rights to the asset
Offer a personal loan directly You control the terms

The Bottom Line

Cosigning means taking on 100% of the risk for someone else’s loan with 0% of the benefit. If the borrower could handle the loan, they wouldn’t need a cosigner. Think of cosigning as giving a gift of the full loan amount — because there’s a 38% chance you’ll be making payments. If you’d give them the money as a gift, cosign. If you wouldn’t, don’t.
