In the United States, your credit score is one of the most important numbers in your financial life. It affects whether you can get a credit card, rent an apartment, finance a car, buy a home, or even qualify for certain jobs.
If you are new to the US financial system—or simply want a clear explanation—this guide explains how credit score works in the USA, how it is calculated, and how you can build or improve your score in 2026.
What Is a Credit Score in the USA?
A credit score is a three-digit number that represents how reliable you are as a borrower. US lenders use this score to assess the risk of lending money to you.
Credit scores typically range from 300 to 850, with higher scores indicating lower risk.
Which Credit Score Do US Lenders Use?
In the USA, lenders primarily use the FICO Score, developed by Fair Isaac Corporation.
Although another model called VantageScore exists, more than 90% of major US lenders rely on FICO scores when making lending decisions.
When a bank or lender mentions “your credit score,” they are almost always referring to your FICO Score.
Credit Score Ranges in the USA
| Credit Score | Category | Meaning |
|---|---|---|
| 800–850 | Excellent | Best rates and approvals |
| 740–799 | Very Good | Strong credit profile |
| 670–739 | Good | Accepted by most lenders |
| 580–669 | Fair | Higher interest rates |
| 300–579 | Poor | Limited credit access |
A score of 670 or higher is generally considered good in the US.
How Credit Score Is Calculated in the USA
Your US credit score is calculated using five major factors:
1. Payment History (35%)
This is the most important factor. It tracks whether you pay your bills on time.
Late payments, defaults, collections, and bankruptcies can significantly reduce your score. Even one missed payment can stay on your credit report for up to 7 years.
1. Always pay at least the minimum amount due
2. Set up automatic payments if possible
2. Credit Utilization (30%)
Credit utilization refers to how much of your available credit you are using.
Example:
- Credit limit: $5,000
- Balance used: $1,500
- Utilization: 30%
Most US lenders prefer utilization below 30%, but the best scores often keep it under 10%.
High utilization signals financial stress—even if you pay on time.
3. Length of Credit History (15%)
This factor measures how long you have been using credit in the USA.
- Older accounts help your score
- Closing old cards can reduce average account age
Keep your oldest credit cards active
Avoid unnecessary closures
4. Credit Mix (10%)
US lenders like to see different types of credit, such as:
- Credit cards
- Auto loans
- Student loans
- Mortgages
You do not need all types, but a healthy mix improves your profile over time.
5. New Credit & Inquiries (10%)
Each time you apply for credit, a hard inquiry is recorded on your credit report.
Too many applications in a short period can lower your score temporarily.
Hard Inquiry vs Soft Inquiry (Very Important)
Not all credit checks affect your score.
Soft inquiries (no impact):
- Checking your own credit score
- Pre-approved credit offers
- Employer background checks
Hard inquiries (impact score):
- Credit card applications
- Auto loans
- Mortgages
Multiple hard inquiries within a short time can signal risk to lenders.
Credit Bureaus in the USA
Your credit information is maintained by three major credit bureaus:
- Experian
- Equifax
- TransUnion
Your score may vary slightly across bureaus because lenders may report information to one bureau and not all three. This is normal.
How to Build Credit Score in the USA (Beginner-Friendly)
If you are starting from scratch, these are the most effective ways to build US credit:
1. Get a Secured Credit Card
You deposit money upfront, which becomes your credit limit. This is one of the fastest ways to start building credit.
2. Become an Authorized User
Being added to a trusted person’s credit card account can help you benefit from their positive history.
3. Pay Every Bill on Time
On-time payments consistently improve your score.
4. Keep Balances Low
Aim to use less than 30% of your available credit—lower is better.
Credit Score for New Immigrants in the USA
New immigrants usually arrive with no US credit history, even if they had strong credit in their home country.
This is completely normal.
Best options for immigrants include:
- Secured credit cards
- ITIN-based credit cards
- Starter cards from US banks
With responsible usage, many immigrants reach a 650–700 credit score within 6 to 9 months.
How Often Does Credit Score Update?
Credit scores typically update every 30 to 45 days, depending on when lenders report your account activity to the credit bureaus.
Positive habits take time—but they compound.
Understanding how credit score works in the USA is the first step toward financial stability. A strong credit score can save you thousands of dollars in interest and open doors to better financial opportunities.
Build slowly, stay consistent, and focus on long-term habits—not quick fixes.
