In most of the United States, you have to be at least 18 years old to get a loan on your own. That’s the age at which nearly every state treats you as a legal adult who can sign an enforceable contract, and a loan agreement is a contract. A few states set the general age of majority higher, and certain kinds of credit—credit cards especially—come with their own federal age rules layered on top.
Why 18 Is the Standard
The age of majority is the point at which you stop being a minor and become a legal adult. In the vast majority of states, that’s 18. Once you cross it, you can enter contracts that courts will enforce against you, which is exactly what a lender needs before handing over money.
Under longstanding common law, a contract signed by someone under the age of majority is voidable at the minor’s option. The minor can walk away; the lender cannot. If a teenage borrower stops paying, the bank may have no practical way to sue for the balance or repossess collateral. That one-sided risk is why financial institutions set a firm age floor on loan applications. Reaching 18 doesn’t guarantee approval—lenders still check your credit history, income, and ability to repay—but it clears the first legal hurdle.
States Where the Age Is Higher
A small number of states define the age of majority differently. One sets it at 19. Another defines “minor” as anyone under 21 for certain statutory purposes. These higher thresholds don’t automatically mean you have to wait longer to borrow.
At least one state with a higher general age of majority explicitly allows 18-year-olds to enter binding contracts, sign promissory notes, and execute mortgages. Another with a general “minor” definition of under 21 carves out an exception for contracts affecting personal or real property, defining “minor” as under 18 for those purposes. Because loans are contracts, an 18-year-old in that state can usually borrow without issue. If you live somewhere the general majority age is above 18, check whether your state’s law contains a specific carve-out for financial contracts before you apply.
Credit Cards Require You To Be 21 (Or Prove You Can Pay)
Turning 18 is enough for most loans, but not for a credit card in your own name. Federal law bars issuers from opening a credit card account for anyone under 21 unless the applicant meets one of two conditions:
- You submit financial information showing you can independently repay the debt, or
- A co-signer who is at least 21 and has the means to cover the account agrees to share liability. A parent, guardian, or spouse can serve this role.
These rules come from the Credit CARD Act of 2009, codified at 15 U.S.C. § 1637(c)(8).1Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans Congress wanted to keep issuers from extending revolving credit to young adults who couldn’t manage it. If you’re 18 to 20 and have steady earnings you can document with pay stubs, tax returns, or bank statements, you can qualify on your own. If not, the co-signer becomes legally responsible for what you charge.
These restrictions apply to credit cards and other open-end credit plans. They do not apply to personal loans, auto loans, or mortgages, which follow your state’s general age-of-majority rules.
Federal Student Loans Have No Minimum Age
Federal student loans run on their own eligibility rules under the Higher Education Act. The requirements listed in 20 U.S.C. § 1091 do not include a minimum age.2Office of the Law Revision Counsel. 20 USC 1091 – Student Eligibility To qualify for federal grants, loans, or work-study, you have to be enrolled or accepted at an eligible institution, maintain satisfactory academic progress, be a U.S. citizen or eligible noncitizen, and meet other program-specific requirements.
Because no age floor exists, a 17-year-old who enrolls in college can sign a federal student loan promissory note, and the government treats that obligation as enforceable even before the borrower reaches their state’s age of majority. Federal student loans are one of the few forms of credit routinely available to borrowers under 18.
Mortgages, Auto Loans, and Personal Loans
For mortgages, conventional loans backed by Fannie Mae require the borrower to have “reached the age at which the mortgage note can be enforced in the jurisdiction where the property is located.”3Fannie Mae. General Borrower Eligibility Requirements In practice, that’s 18 in most states, and there is no maximum age. FHA-insured mortgages work the same way in effect: co-borrowers and co-signers have to sign the note (and co-borrowers must take title), which a minor generally can’t do.
Auto loans and personal loans follow your state’s age-of-majority rule too. If you’re a young applicant, expect closer scrutiny than an older borrower would get. A thin credit file and short employment history are common obstacles. A co-signer with established credit can improve your odds, but that person takes on full liability for the debt if you stop paying.
Emancipated Minors Can Borrow Earlier
Emancipation is a legal process that gives a minor adult status before they reach the age of majority. A judge has to find that the minor is self-sufficient and capable of managing their own affairs. Requirements vary by state, but usually involve filing a petition and showing financial independence.
Once emancipated, the minor can enter binding contracts, including loans, that would otherwise be voidable. To use this status on a loan application, you’ll need formal documentation—typically a certified copy of the court order. Some states issue identification reflecting emancipated status. Without verified paperwork, a lender will treat you as a minor and decline the application. Even with the order, lenders still run the usual credit and income checks, and a limited financial history at a young age can make approval difficult.
Building Credit Before You Can Borrow
If you’re under 18, or under 21 and trying to get a credit card without independent income, there are ways to start building a credit history so you’re in a stronger position later.
- A parent or guardian can add you as an authorized user on their credit card. There’s no federal minimum age for authorized users; individual issuers set their own minimums, typically between 13 and 16. If the issuer reports authorized-user activity and the primary cardholder pays on time, your credit file benefits.
- After you turn 18, a co-signer with strong credit can help you qualify for an auto loan, personal loan, or mortgage you might not get on your own. The co-signer shares legal responsibility for the debt.
- Also after 18, you can apply for a secured credit card, which requires a cash deposit as collateral. Secured cards are designed for people with little or no credit history and don’t require high income.
Starting with authorized-user status or a secured card gives you a track record that makes lenders more willing to approve larger loans later.
Don’t Lie About Your Age
Misrepresenting your age on a loan application can backfire badly. In several states, a minor who lies about their age in writing to get a loan loses the protection that normally lets minors void their contracts. The loan becomes enforceable, so you owe the full balance even though you were underage when you signed.
Beyond enforceability, false statements on a loan application can constitute fraud. Applications typically require you to certify that the information you provide is accurate, and knowingly making a false statement to obtain credit can carry civil or criminal consequences depending on the circumstances and jurisdiction. Getting a loan a year or two early isn’t worth the exposure.
