Summary

• Adding your child as an authorized user on your credit card, or opening a joint account with them, is a common way to help them start building credit before they turn 18.

• A credit score is a three-digit number that lenders use to judge how likely someone is to repay borrowed money, and it's shaped by factors like payment history, credit utilization, and the length of their credit history.

• The three major credit bureaus—Experian, TransUnion, and Equifax—collect and maintain credit information. You can request your child’s credit report from each bureau to review for potential errors or signs of identity theft.

• Once your child turns 18, tools like a secured credit card, a student credit card, and credit builder loans can help them grow their own credit profile independently.

• Teaching good credit habits early, including responsible spending, on-time payments, and an understanding of how credit works, gives your child a strong foundation for their financial future.

Whether your child is still in high school or heading off to college, thinking about their financial future now can make a real difference later. Good credit may open financial doors for them later in life. It can determine whether your child is able to qualify for their first apartment, gets a reasonable rate on a car loan, or is able to get approval for a student loan. 

Starting early doesn’t mean taking on financial responsibilities before they’re ready. It’s about helping them build a foundation so that when they choose to use credit in the future, they may be better prepared to manage it responsibly.

This article explains what credit is, why it can be important, and outlines steps you can consider to help your child begin building a credit history over time so they may be better prepared if they choose to use credit in the future.

What is credit, and why does it matter for your child?

Credit is essentially a measure of how trustworthy someone is as a borrower, meaning a person who takes on debt with a promise to repay it. When your child applies for a loan, rents an apartment, or even applies for certain jobs one day, the people on the other side of that decision will likely look at their credit to help make decisions.

A credit score is a three-digit number that typically falls somewhere between 300 and 850. It's generated by companies like FICO® (Fair Isaac Corporation), which is one of the most widely used scoring models in the U.S. The higher the number, the better. On the FICO® scale, a score between 670 and 739 is generally considered good, while scores of 740 and above fall into the "very good" or "exceptional" range. A higher credit score may mean lower interest rates, better loan terms, and more financial options overall. 

The major credit bureaus, Experian, TransUnion, and Equifax, are the three companies that collect and maintain credit information on consumers in the United States. They're often called the major credit bureaus, and lenders regularly report account activity to them. A credit report is the detailed document these bureaus produce, summarizing someone's credit accounts, balances, payment history, and other financial behaviors. A credit score is then calculated using the information in that report. 

Your child's credit profile, the full picture of their credit information across all three bureaus, doesn't build itself. It needs accounts, activity, and time. The earlier you start, the more history they'll have when it counts.

How a credit score is calculated

Before you can help your child build credit, it helps to understand what actually goes into a credit score. The FICO® model breaks it down into five main factors: 

• Payment history (35%): Whether bills and balances have been paid on time. On-time payments are the single biggest factor in any credit score.

• Credit utilization (30%): How much of the available credit limit is being used. Lower is better, and keeping utilization under 30% is generally a healthy target.

• Length of credit history (15%): How long accounts have been open. This is one reason starting early matters so much.

• Credit mix (10%): Having different types of credit, like a credit card account alongside an installment loan, can help.

• New credit (10%): Opening several new accounts at once can temporarily lower a score.

Understanding these factors helps you make better decisions about how to help your child build a strong credit foundation from the start.

Start with the authorized user strategy

One of the most accessible ways to help a child build credit early is to add them as an authorized user on your credit card. An authorized user is someone who gets permission to use another person's credit card account but isn't legally responsible for paying the bill. As the primary cardholder, you stay fully responsible for all charges. 

Here's why this matters: if your credit card issuer, the bank or financial institution that issued your card, reports authorized user activity to the credit bureaus, that account history can show up on your child's credit report too. That means your child could start building a credit history years before they're old enough to open their own account. 

Not all credit card issuers handle this the same way, though. Some issuers only begin reporting authorized user activity once the user turns 18. Others may not report it at all if you don't provide your child's Social Security number when adding them. It's worth calling your credit card company directly to ask about their policy before assuming the strategy is working. 

There's also an important thing to keep in mind: your behavior on that account directly affects your child’s credit as well. So high balances, missed payments, or irresponsible use can hurt their credit just as much as it can hurt yours.

Setting up authorized user status: what to do

If you decide the authorized user approach is right for your family, here's a practical breakdown of how to approach it:

• Check your issuer's policy first. Contact your credit card company and confirm whether they report authorized user activity to all three credit bureaus and whether they have a minimum age requirement for authorized users. Age requirements can vary by issuer. 

• Provide your child's Social Security number. Many issuers need this to actually link the account to your child's credit file. Without it, the account may never appear on their credit report.

• Choose the right account. Pick a card with a long history of on-time payments, a low balance relative to its credit limit, and no or minimal annual fees. That positive history is what you want reflected on your child's report. 

• Set clear boundaries. Talk to your child about how the card works, what spending, if any, is allowed, and why on-time payments matter so much. This is a great opportunity to introduce financial literacy, which refers to the knowledge and skills someone needs to make informed and effective financial decisions.

• Monitor the account regularly. Keep an eye on balances and make sure payments are made on time every month.

What your child's credit score looks like before age 18

Here's something many parents don't realize: even if your child has authorized user history on their credit report, most scoring models won't generate an actual credit score for them until they turn 18. The credit history may be there, but lenders typically don't use it in a formal scoring context until your child is an adult. 

The good news is that this history still counts. If you add your child to a well-managed account when they're 10 or 12, that entire history will already be part of their credit file when they turn 18. That means they could enter adulthood with years of positive credit history already behind them, rather than starting with no credit or a thin credit file. That head start can make a meaningful difference when they go to apply for their first credit card, car loan, or first apartment.

Tools your child can use once they turn 18

When your child turns 18, a whole new set of options becomes available to help them build credit in their own name. This is an exciting milestone and a great time to shift from the authorized user strategy toward independent credit building.

Secured credit cards

A secured credit card is a type of credit card that requires a cash deposit upfront, and that deposit typically becomes the card's credit limit. For example, a $300 deposit usually means a $300 spending limit. The card works like a regular credit card for everyday purchases, but the deposit protects the issuer if the cardholder doesn't pay. 

Because secured credit cards are reported to the credit bureaus just like credit cards, using one responsibly, keeping the balance low and paying it off each month, can help your child build credit steadily. Some secured cards also have a path to upgrade to an unsecured card after several months of responsible use, at which point the deposit is typically returned. 

Student credit cards

A student credit card is a credit card designed specifically for college students and young adults who are new to credit. These cards typically come with lower credit limits, fewer fees, and sometimes perks like cash back on everyday purchases. Some even offer rewards for good grades. 

Under the Credit CARD Act of 2009, applicants under 21 generally must demonstrate independent income or apply with a co-signer—someone who agrees to share responsibility for the debt if the primary cardholder does not pay. In practice, some issuers may not offer co-signer options, so applicants between 18 and 20 often need their own source of income to qualify.

Credit builder loans

A credit builder loan is a financial product offered by some credit unions, banks, and neobanks that help people with little or no credit history establish a credit record. Instead of receiving the money upfront, the borrower makes monthly payments into a locked savings account over a set period. Once the loan is paid off, they receive the funds. Each on-time payment gets reported to the credit bureaus, helping to build a positive payment history. 

This option is especially helpful for young adults who want to build credit without the risk of overspending that can sometimes come with a credit card.

Role of debit cards, checking, and savings accounts

Many parents give their children a debit card connected to a checking account as a first step toward managing money. A checking account is a bank account used for everyday spending, and a debit card draws directly from that balance. A savings account is a separate bank account designed for storing money and earning interest over time.

Both are valuable tools for teaching money management, which is the practice of budgeting, saving, and spending wisely. But here's the important distinction: a debit card and a checking account do not build credit. Debit transactions aren't reported to the credit bureaus, so no matter how responsibly your child uses their debit card, it won't help their credit score. 

That said, these tools are still a great starting point. They help your child understand how to track spending, avoid overspending, and avoid common credit mistakes before they ever touch a credit card. Think of checking accounts and debit cards as the training ground for the real thing.

Some bank accounts and credit products offered by financial institutions are insured by the FDIC (Federal Deposit Insurance Corporation), a U.S. government agency that protects depositors' money up to certain limits. When you see "member FDIC" listed on a bank's website or materials, it means eligible deposits are federally insured. This is worth knowing as you help your child choose where to bank.

When your child heads to college

College is often when young adults first start making real financial decisions on their own. It's also when having even a small amount of credit history can come in handy. College students who already have a credit profile may find it easier to find housing, qualify for a student loan without relying entirely on a parent, or get approved for a line of credit, which is a flexible borrowing arrangement that allows someone to draw funds up to a set limit as needed. 

If your child is heading into their first year of college with no credit history at all, a secured credit card or a student credit card are both good places to start. Encourage them to use the card for small, predictable monthly payments they already plan to make, like a streaming subscription or a monthly phone bill, and to pay the balance in full each month. This keeps interest rates from becoming a problem and builds a track record of on-time payments over time.

The age requirement for opening a credit card in their own name is 18 in the U.S., though as mentioned earlier, additional income requirements apply until age 21. 

Teaching good credit habits alongside credit building

Giving your child access to credit without the knowledge to use it wisely can do more harm than good. The goal isn't just to help a child build credit, it's to help them understand it. Here are some foundational habits worth teaching:

• Always pay on time. Payment history is the single largest factor in a credit score. Even one late payment can have a noticeable negative impact. Setting up automatic monthly payments can help prevent mistakes.

• Keep balances low. Using a large portion of an available credit limit can hurt a credit score, even if the balance gets paid off monthly. Keeping spending well below the credit limit is a key part of responsible credit use.

• Don't open too many accounts at once. Each application typically triggers a hard inquiry, which can temporarily lower a score. Encourage your child to be selective about what they apply for.

• Check the credit report regularly. Anyone can request a free credit report from each of the three major credit bureaus at AnnualCreditReport.com. Reviewing reports helps catch errors or unfamiliar accounts early. 

• Understand that credit is a tool, not free money. Teaching your child the difference between a debit card and a credit card, and explaining how interest rates work if a balance isn't paid in full, is one of the most valuable financial responsibility lessons you can give them.

Personal finance education doesn't have to be a formal sit-down conversation. It can happen naturally as part of everyday life, at the grocery store, when reviewing a bank statement, or when talking about why good credit helped someone get a better deal on a car.

Protecting your child from identity theft

One thing many parents don't consider is that children can be targets for identity theft, which is when someone illegally uses another person's personal information, like their name or Social Security number, to open accounts or take on debt. Because children are less likely to check their own credit, fraud can go undetected for years. 

Under federal law, parents and guardians can request a free credit freeze for a child under 16. A credit freeze restricts access to your child's credit file, making it much harder for anyone to open a fraudulent account in their name. Even if no credit file exists yet, the credit bureaus are required to create one and freeze it upon request. 

You'll need to contact Experian, TransUnion, and Equifax separately to place the freeze with each one, and you'll typically need to submit a written request along with identifying documents. It's a straightforward process, and it can save your child from a lot of headaches down the road.

A note on reviewing fees and account terms

As you explore credit options for your child, keep an eye on the details. Some cards come with annual fees, which are yearly charges just for holding the card. Some carry higher interest rates than others that can make carrying a balance very expensive. Look for options with no or low annual fees and clear, transparent terms, especially when your child is just starting out.

Also be cautious about any product that seems to promise fast or guaranteed results for credit building. Building strong credit takes consistent, positive behavior over time. There are no real shortcuts, but there is a clear path forward, and you're already on it by learning about this now.

Helping your child build credit is one of the most practical and lasting gifts you can give them. Strong credit, built on a foundation of good credit habits and financial literacy, can shape their financial decisions for decades. Whether you start by adding them as an authorized user today or help them open their first secured credit card at 18, every step forward matters.
