You get a credit score when you borrow money or use credit, and the three major credit bureaus calculate it based on your payment history
A credit score is not something you request or sign up for. It builds automatically when you use credit — a credit card, a loan, a mortgage, or even a utility bill that reports to the bureaus. The three major credit reporting agencies (Equifax, Experian, and TransUnion) collect information about your borrowing and payment behavior, then use that data to calculate a score. You do not need to do anything to start the process; lenders report your account activity to these bureaus on their own schedule, usually monthly.
Your score appears in your credit report, which is a record of your credit accounts, payment history, and public records like bankruptcies or liens. The most common scoring model is FICO, which ranges from 300 to 850. A higher score signals lower risk to lenders. You can see your own score and report by requesting them directly from the bureaus or through services that offer free or paid access.
Key Takeaways
- Your credit score builds automatically when you use credit products like credit cards or loans that report to the three major bureaus.
- You can view your credit report for free once per year from each bureau through AnnualCreditReport.com, which is the official government site.
- FICO scores range from 300 to 850 and are calculated from five factors: payment history (35%), amounts owed (30%), length of credit history (15%), credit mix (10%), and new credit (10%).
- If you have no credit history, you can start building a score by opening a credit card, becoming an authorized user on someone else's account, or taking out a credit-builder loan.
Where to get your credit report and score for free
The federal government requires each of the three credit bureaus to give you one free credit report per year. You request all three through AnnualCreditReport.com, which is the official site run by the bureaus themselves. You can order all three reports at once or space them out throughout the year. The site will ask you to verify your identity by answering questions about your credit history or providing a Social Security number.
Your free annual report shows what information the bureaus have on file but does not include your numerical score. To see your actual FICO score, you have several options. Many credit card issuers now show your score free in your online account or mobile app — check with your bank or card company first. Credit monitoring services like Credit Karma, Credit Sesame, and Experian's own website offer free score estimates (usually VantageScore, a different model than FICO, but in the same range). If you want your official FICO score, you can buy it directly from MyFICO.com for a one-time fee, or some lenders will show it to you when you explore for credit.
What information goes into your credit score
FICO calculates your score from five categories of information in your credit report. Payment history (35% of your score) is the largest factor — it tracks whether you paid your bills on time. A single late payment can lower your score, and the more recent the late payment, the bigger the damage. Amounts owed (30%) looks at how much you currently owe across all your accounts and compares it to your credit limits. This is called your utilization ratio; using less than 30% of your available credit is generally better for your score.
Length of credit history (15%) measures how long your oldest account has been open and the average age of all your accounts. Older accounts help your score. Credit mix (10%) means having different types of credit — credit cards, installment loans, mortgages, and so on. New credit (10%) tracks how many new accounts you have opened recently and how many times you have applied for credit. Multiple applications in a short time can lower your score temporarily.
How to build a credit score if you have none
If you have never borrowed money or used credit, you have no credit history and no score. Lenders cannot assess your risk, so many will not lend to you. To start building, you need to use credit in a way that gets reported to the bureaus. A credit-builder loan is designed for this purpose. You borrow a small amount (usually $500 to $1,000), which the lender holds in a savings account. You make monthly payments on the loan, and those payments are reported to all three bureaus. Once you repay the loan, you get the money back. Credit unions and some banks offer these loans.
A second route is to open a secured credit card, which requires a cash deposit (often $200 to $2,500) that becomes your credit limit. You use the card like a regular card, pay your bill on time each month, and the issuer reports your activity to the bureaus. After six to twelve months of on-time payments, many issuers will convert it to a regular unsecured card and return your deposit. A third option is to become an authorized user on someone else's credit card account. If the primary cardholder has good payment history and low utilization, their account activity may be reported under your name and help build your score — though this depends on the card issuer and the bureau.
Why your score might not appear right away
Even after you open a credit account, your score may not show up for several weeks or months. Credit bureaus need time to receive the information from lenders, process it, and calculate a score. Most lenders report monthly, so your first payment may not appear on your report for 30 to 60 days. Some scoring models require a minimum amount of credit history before they will generate a score at all — for example, FICO requires at least one account that has been open for six months and at least one account that has been reported to the bureau within the last six months.
If you have just opened your first account, check back in two to three months. If you still see no score after that, contact the credit bureau directly to confirm they have received the account information from your lender. You can reach them through their websites: Equifax.com, Experian.com, or TransUnion.com.
How to monitor your score over time
Once you have a score, you can track it regularly without paying anything. Most credit card issuers, banks, and loan servicers now show your score free in your online account or app — log in and look for a section labeled "credit score," "credit insights," or "credit monitoring." These updates are usually monthly. Free credit monitoring services like Credit Karma update your score weekly and send alerts when something changes on your report, like a new account or a late payment.
Checking your own score does not hurt it. What does hurt is when a lender or creditor checks your score as part of a lending decision — that is called a hard inquiry and can lower your score slightly. Checking your own score is called a soft inquiry and has no effect. You can also request a copy of your credit report from each bureau once a year through AnnualCreditReport.com and review it yourself for errors or accounts you do not recognize.
Frequently Asked Questions
Can I get a credit score without a credit card?
Yes. A credit-builder loan, a car loan, a mortgage, or even a utility bill that reports to the bureaus can build your score. You do not need a credit card specifically, though credit cards are a common way to build history because they are straightforward to open and report monthly.
How long does it take to build a credit score from scratch?
Most scoring models need at least six months of credit history before they will generate a score. After that, your score will continue to change based on your payment behavior and account activity. Significant improvement usually takes several months to a year of on-time payments and low credit card balances.
Does checking my credit score lower it?
No. When you check your own score or report, it is a soft inquiry and does not affect your score. Only hard inquiries — when a lender checks your score as part of a lending decision — can lower your score slightly and temporarily.
What if I find an error on my credit report?
Contact the credit bureau that issued the report and file a dispute. You can do this online, by mail, or by phone. The bureau must investigate within 30 days and remove the error if it is incorrect. You can also contact the lender or creditor who reported the wrong information and ask them to correct it.
Why is my credit score different on different websites?
Different companies use different scoring models. FICO is the most common, but VantageScore, Experian's own model, and others exist. The same credit report can produce different scores depending on which model is used. This is normal and does not mean one score is wrong.
