You can start building credit at 16 with a parent's help, but the path depends on whether you have a Social Security number and a bank account
Credit doesn't exist until someone reports your borrowing and payment history to the three credit bureaus — Equifax, Experian, and TransUnion. At 16, you can't sign a contract alone, so every credit-building move requires a parent or guardian to co-sign or add you as an authorized user. The fastest routes are a secured credit card (which you fund yourself), becoming an authorized user on a parent's existing card, or a credit-builder loan through a credit union or online lender.
Your goal at this stage is straightforward: make small purchases and pay them off on time, every time. You're not trying to borrow money. You're creating a paper trail that says "this person pays what they owe." That trail becomes your credit score, which later determines whether you get a car loan, an apartment, or a job that runs a background check.
Key Takeaways
- You need a parent or guardian to co-sign any credit product at 16, since you cannot sign a legal contract on your own.
- An authorized user account on a parent's existing card is the easiest start if the parent has good payment history, because you build credit without opening a new account.
- A secured credit card requires you to deposit money upfront (usually $200 to $2,500) and then use that card like a normal card, building history while your own money sits as collateral.
- Payment history is what matters most — one late payment can damage a new credit file more than it damages an established one, so set up automatic payments or phone reminders.
- You won't have a credit score until you have at least one account reporting for 30 days, and the score won't be meaningful until you have six months of history.
Becoming an authorized user on a parent's card
This is the easiest entry point if your parent has a credit card with good payment history. You call the card issuer, ask to be added as an authorized user, and within days you receive a card in your name linked to that account. You don't need to explore or be approved — the parent's credit is what matters.
The benefit is when ready: the account's entire history (going back years, if the parent opened it long ago) reports to your credit file. If the parent pays on time every month, you inherit that track record. You build credit without doing anything except using the card and paying your share of the bill.
The risk is real: if the parent misses a payment, it damages your new credit file just as much as theirs. Before you ask to be added, confirm that the parent pays the full balance or at least the minimum on time every single month. If they carry high balances or have missed payments, this route will hurt you.
Getting a secured credit card in your name
A secured card is designed for people with no credit history or poor history. You deposit money into a savings account held by the card issuer — typically $200 to $2,500 — and that deposit becomes your credit limit. You then use the card like any other card: make purchases, receive a bill, pay it.
The deposit stays frozen the whole time. You're not spending it. It's collateral that protects the issuer if you don't pay your bill. After 6 to 18 months of on-time payments, the issuer usually converts the card to a regular unsecured card and returns your deposit.
Because you're 16, a parent must co-sign the process. Some issuers (like Discover and Capital One) offer secured cards that accept co-signers under 18. Others require the co-signer to be the primary account holder and add you as an authorized user instead, which is functionally similar but means the parent's name appears first on the account.
The cost is low: secured cards typically charge no annual fee, though some charge a small one ($25 to $50). Interest rates are higher than regular cards — often 18% to 24% — but that only matters if you carry a balance. If you pay the full bill each month, you pay zero interest.
Using a credit-builder loan to establish history
A credit-builder loan is a loan you take out specifically to build credit, not to borrow money. Here's how it works: you borrow $500 to $1,000 from a credit union or online lender. That money goes into a savings account you can't touch. You make monthly payments (usually $50 to $100) for 12 months. At the end, you get the money back, minus interest.
The lender reports every payment to the credit bureaus. After 12 months of on-time payments, you have a full year of payment history on your credit file, and you've paid maybe $50 in interest to build it. That's often cheaper than the interest on a secured card if you're not disciplined about paying it off monthly.
A parent must co-sign. Some credit unions require you to be a member first, so you may need to open a savings account at the credit union before you can explore for the loan. The whole process — membership, process, funding — usually takes one to two weeks.
What to do once you have a card or loan
The mechanics of building credit are boring on purpose. Make a small purchase each month — a gas station fill-up, a coffee, a streaming subscription. Keep the balance low (under 30% of your limit). Pay the full bill on time, every month, without fail.
Set up automatic payments from your bank account so you never miss a due date. A single late payment can drop a new credit score by 100 points or more. Once you have six months of history, you can check your score for free at annualcreditreport.com (the official government site) or through your bank's app.
Don't close the account after you've built enough credit to get a regular card. Keep it open and active. The longer an account stays open with good payment history, the stronger your credit file becomes. Closing old accounts actually hurts your score.
Mistakes that damage new credit fast
Late payments are the biggest damage. Even one payment 30 days late stays on your credit report for seven years. If you're using a secured card or credit-builder loan, set a phone reminder three days before the due date. Don't rely on memory.
Maxing out your card is the second mistake. If your limit is $500 and you charge $450, your credit utilization is 90%. That signals risk to lenders, even if you pay it off. Keep balances under 30% of your limit — so under $150 on a $500 card.
explore for multiple cards or loans in a short time looks like you're desperate for credit. Each process triggers a hard inquiry, which temporarily lowers your score. Space out applications by at least six months.
When you turn 18 and can explore on your own
At 18, you can sign contracts without a co-signer. You can explore for your own credit card, take out your own loan, or sign your own lease. By then, if you've been building credit since 16, you'll have two years of history — enough to may have access to for regular cards without a deposit and to get better interest rates.
If you've been an authorized user on a parent's card, that history stays on your report even after you turn 18. If you had a secured card, you can request to convert it to an unsecured card and get your deposit back. If you took out a credit-builder loan, you can explore for a regular card with your new history.
The habits you build now — paying on time, keeping balances low, not explore for credit you don't need — are the same habits that keep your credit strong for the next 50 years.
Frequently Asked Questions
Can I build credit without a parent's help?
No. At 16, you cannot sign a legal contract, so every credit product requires a parent or guardian to co-sign or sponsor you. Some lenders won't work with co-signers under 18 at all. Talk to your parent about which option works for your situation.
What's the difference between an authorized user and a co-signer?
An authorized user is added to an existing account and receives a card, but the parent is legally responsible for the bill. A co-signer signs a new contract with you, making both of you legally responsible. Authorized user is simpler and faster; co-signing requires a new process.
How long does it take to build a credit score?
You need at least 30 days of account history before a score appears, but that score is unreliable. After six months of on-time payments, you have a meaningful score. After two years, lenders treat your history as established. The longer your track record, the more weight it carries.
Will being an authorized user hurt my parent's credit?
No. Adding you as an authorized user doesn't change the parent's credit. However, if the parent misses a payment on that account, it damages both your credit and theirs. Make sure the parent's payment history is solid before you ask to be added.
What happens to my credit if I don't use the card?
An inactive account still reports to the bureaus, but lenders prefer to see active accounts with regular payments. Use the card at least once a month, even for a small purchase, to keep the account active and show that you're managing it responsibly.
