A credit score is one of the most important numbers in the U.S. financial system. It can affect your ability to qualify for a credit card, personal loan, auto loan, mortgage, apartment rental, and sometimes other financial services.
If you are new to credit in the United States, understanding your credit score can help you make better financial decisions.
In this beginner-friendly guide, we explain what a credit score is, how it works, what affects it, and how you can build and improve your credit over time.
What Is a Credit Score?
A credit score is a three-digit number that represents the information in your credit history. Lenders and creditors may use it to help evaluate how likely you are to repay borrowed money.
Most commonly used credit scores range from 300 to 850.
Generally, a higher score indicates a stronger credit history, while a lower score can make it harder or more expensive to qualify for certain types of credit.
Your credit score is calculated from information found in your credit reports.
What Is a Good Credit Score?
Credit-score ranges can vary depending on the scoring model. For the commonly used FICO Score model, the ranges are:
| FICO Score | General Category |
|---|---|
| 300–579 | Poor |
| 580–669 | Fair |
| 670–739 | Good |
| 740–799 | Very Good |
| 800–850 | Exceptional |
These categories are useful as a general guide, but lenders may have their own requirements.
Having a particular score does not guarantee approval for a loan or credit card.
Why Is Your Credit Score Important?
Your credit score can influence several financial decisions.
For example, a lender may consider your credit score when you apply for:
- Credit cards
- Personal loans
- Auto loans
- Mortgages
- Certain private student loans
- Other forms of credit
Your credit profile can also affect the interest rate and terms you are offered.
A stronger credit profile may help you qualify for more favorable borrowing terms, although approval and pricing depend on other factors as well.
What Factors Affect Your Credit Score?
Different credit-scoring models use different formulas, but payment history, amounts owed, length of credit history, new credit, and credit mix are important factors in the widely used FICO Score.
1. Payment History
Payment history is a major part of your FICO Score.
Making payments on time can help maintain a healthy credit history.
Late payments can negatively affect your credit, particularly when they are reported to the credit bureaus.
Tip: Set up automatic payments or reminders so you don't accidentally miss a due date.
2. Amounts Owed and Credit Utilization
Credit utilization refers to how much of your available revolving credit you are using.
For example, if your credit card has a $5,000 limit and your balance is $1,000, your utilization is 20%.
Keeping credit card balances relatively low compared with your limits can be helpful for your credit profile.
3. Length of Credit History
The age of your credit accounts can also matter.
Generally, a longer credit history gives scoring models more information about your experience managing credit.
Closing an older credit card may therefore have consequences for your credit profile, depending on your overall situation.
4. New Credit
Applying for several new credit accounts within a short period can result in multiple hard inquiries.
Too many recent applications may be viewed as a sign of increased credit risk by some scoring models.
This does not mean you should never apply for new credit. It means you should apply thoughtfully and only when appropriate.
5. Credit Mix
Credit mix refers to the different types of credit accounts in your credit profile.
Examples can include:
- Credit cards
- Installment loans
- Auto loans
- Mortgages
You do not need to open accounts you do not need simply to create a certain credit mix.
What Is the Difference Between a Credit Report and a Credit Score?
A credit report and credit score are not the same thing.
A credit report contains information about your credit accounts and payment history.
A credit score is a number calculated using information from your credit report.
In the United States, the three major nationwide consumer reporting companies are:
- Equifax
- Experian
- TransUnion
Information on your reports can differ between bureaus, so your scores may also differ depending on which credit report and scoring model are being used.
What Is a FICO Score?
FICO Score is one of the most widely recognized credit-scoring systems in the United States.
FICO Scores are developed by Fair Isaac Corporation and are used by many lenders.
There are multiple versions of FICO Scores, and lenders may use different versions depending on the type of credit being evaluated.
Therefore, the score you see from one source may not be exactly the same score a lender uses.
What Is a VantageScore?
VantageScore is another credit-scoring model used in the United States.
It was developed by Equifax, Experian, and TransUnion.
Like FICO, VantageScore uses information from credit reports to calculate a numerical score.
Because different scoring models can use different calculations and versions, it is normal for consumers to see different credit scores.
How Can You Check Your Credit Score?
There are several ways to access a credit score.
Some banks, credit card companies, and financial websites provide free credit-score monitoring as a customer benefit.
You should also regularly review your credit reports for incorrect information.
Under federal law, consumers are entitled to free credit reports from each of the three nationwide credit reporting companies through the official AnnualCreditReport.com website.
Remember that a free credit report is not necessarily the same thing as a free credit score.
How Can You Improve Your Credit Score?
Building good credit usually takes time. There is no legitimate overnight method that guarantees a major increase in your score.
Here are practical steps you can take:
Pay Your Bills on Time
Payment history is important, so make payments by their due dates.
Keep Credit Card Balances Under Control
Try not to use a large portion of your available credit.
Avoid Unnecessary Credit Applications
Only apply for new credit when you have a genuine need.
Check Your Credit Reports
Review your reports for accounts or information that you do not recognize.
Dispute Inaccurate Information
If you find inaccurate information on a credit report, you can contact the appropriate credit reporting company and the company that provided the information to dispute it.
Be Patient
Building a strong credit history is a long-term process. Consistent financial habits are generally more important than trying to make a quick change.
How Long Does It Take to Build Credit?
There is no fixed timeline for building credit.
If you are starting from zero credit history, it may take several months or longer before you have enough information for certain scoring models to generate a score.
Your progress depends on factors such as:
- How many accounts you have
- How long your accounts have been open
- Whether you pay on time
- Your credit utilization
- Recent applications
- The information reported to the credit bureaus
Can You Have a Credit Score Without a Credit Card?
Yes.
A credit card is not the only type of account that can contribute to a credit history.
Certain installment loans and other credit accounts may also be reported to the credit bureaus.
However, not every financial account is reported to every credit bureau.
Does Checking Your Own Credit Score Hurt It?
Generally, checking your own credit score or credit report is considered a soft inquiry and does not hurt your credit score.
A lender checking your credit as part of a credit application may create a hard inquiry, which can affect your score.
The impact of a hard inquiry is generally limited, and its effect depends on the scoring model and your overall credit profile.
Common Credit Score Mistakes to Avoid
If you are building credit in the U.S., try to avoid these common mistakes:
- Missing payment due dates
- Applying for many credit accounts at once
- Carrying very high credit card balances
- Ignoring credit-report errors
- Closing accounts without understanding the possible consequences
- Taking on debt you cannot comfortably repay
- Paying companies that promise a guaranteed instant credit-score increase
Be especially cautious about companies that claim they can remove accurate negative information from your credit history or guarantee a specific score increase.
