How to Build Credit at 18: The 2025 Playbook for Young Adults

Learning how to build credit at 18 is one of the best things you can do for your future. Your credit score affects everything-renting a place, buying a car, or setting up utilities. It can even show up in job background checks.

Luckily, you don't need to wait years to get started. In fact, the earlier you begin, the faster you'll gain financial freedom.

Understand How Credit Scores Work

Before taking action, it's important to know how credit scores are calculated. According to the Consumer Financial Protection Bureau, your credit score includes:

• Payment history - Whether you pay bills on time
  
  
• Amounts owed - How much of your credit you're using
  
  
• Length of credit history - How long have your accounts been open
  
  
• Credit mix - A balance of loans and cards
  
  
• New credit - How many accounts you've opened recently
  
  

Focusing on just one or two of these categories early on can give your score a significant boost.

Jasmine's Journey: 720 by 19

Take Jasmine, for example. She opened a secured card at 18 with a $300 deposit. She only used it for gas and paid it off in full. A few months later, she added rent reporting. By age 19, her score hit 720. That strong credit helped her get a car loan and lease her first apartment-without needing a co-signer.

Step 1: Ask to Be an Authorized User

One of the easiest ways to build credit at 18 is by becoming an authorized user on a parent's or family member's credit card. If they have a strong payment history, you can benefit just by being added.

Importantly, make sure the credit card company reports authorized users to the credit bureaus. Otherwise, it won't help your score.

Step 2: Use Credit Builder Tools to Get Started

Don't want a traditional credit card yet? You're not alone. Many young adults prefer credit builder tools that let you build history safely.

Here are some reliable options:

• Cheers Credit Builder - No hard credit check, no admin fees. Make monthly payments into an FDIC-insured savings account. These payments are reported to all three credit bureaus.

* Cheers is not a bank. Deposit accounts held by Sunrise Bank, Member FDIC.

• Experian Boost - Reports utility and phone bill payments to Experian. It's free and can raise your score quickly.
  
  
• Grow Credit - Helps you build credit by managing payments for subscriptions like Spotify or Netflix.
  
  
• Kikoff - Offers a no-fee, no-interest line of credit designed for beginners.
  
  
• CreditStrong - Provides credit builder accounts backed by a real bank.
  
  

These tools are great for anyone figuring out how to build credit at 18-especially without a full-time job or a large budget.

Step 3: Apply for a Student or Secured Credit Card

If you're ready for more responsibility, student credit cards are a solid next step. They're designed for beginners and often come with lower limits.

If you don't qualify, go with a secured credit card. You pay a refundable deposit, and that becomes your credit limit.

To protect yourself, review your rights at the Federal Reserve's consumer page.

Just remember: only charge what you can afford to pay off. Try to keep your balance below 30% of your limit.

Step 4: Report Your Rent

Are you paying rent? Let it work for you. Platforms like Esusu and RentReporters let you report rent payments to credit bureaus.

Since rent is a regular, high-value payment, it's a powerful way to build credit-without borrowing a dollar.

Step 5: Use "Buy Now, Pay Later" with Caution

Some Buy Now, Pay Later (BNPL) platforms like Klarna and Affirm now report on-time payments to credit bureaus. If used wisely, they can help improve your score.

However, late payments can have the opposite effect. So always read the terms and pay on time.

Step 6: Monitor Your Score Regularly

Once you've taken the first steps, stay on track. You can request a free credit report once a year from each bureau at AnnualCreditReport.com.

For monthly monitoring, tools like Credit Karma or the Experian app are helpful. You'll be able to spot mistakes, track your growth, and stay motivated.

Final Takeaways

Understanding how to build credit at 18 gives you a clear financial advantage. Whether you open a secured card, sign up for Cheers Credit Builder, or simply report rent payments, your credit score will thank you later.

Keep your payments on time, watch your credit utilization, and use tools that fit your life. You'll be surprised how quickly your score can grow.
