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.
