What is a credit score? How it’s calculated

  • Key takeaways

    • A credit score is a number that shapes whether you can borrow money, rent a home, or get affordable insurance, and it’s calculated from your credit report.

    • You don’t have just one credit score, since different scoring models can produce different results from the same report.

    • Most credit scores range from 300 to 850, with a higher score generally making credit easier and less expensive to access.

    • Payment history and how much of your available credit you’re using tend to carry the heaviest weight in most models.

    • Immigrants and other newcomers often start with no credit score at all, simply because they have no U.S. credit history yet.

Your credit score is a number that can shape whether you’re approved to borrow money, rent an apartment, or even qualify for affordable insurance. But if you’re new to the United States, there’s a good chance you don’t have one yet, not because of anything you did wrong, but because a score has nothing to calculate from without a credit history behind it.

This page explains what a credit score is, how it’s actually calculated, and why you likely have more than one score rather than a single fixed number. It also covers what starting from zero looks like for newcomers, and a realistic sense of how that changes over time.

What is a credit score?

A credit score is a number, typically between 300 and 850, that predicts how likely you are to repay a loan on time, based on the information in your credit report. Lenders use it to decide whether to extend credit and on what terms, including the interest rate you’re offered, as the Consumer Financial Protection Bureau(opens in new window) explains. Crucially, credit history represents the raw track record of your borrowing and repayment activity, whereas a credit score is a numerical value calculated from that history using a specific scoring model. While you need a credit history to generate a meaningful credit score, they remain distinct concepts.

How your credit score affects your financial life

A credit score touches more of daily life than most people expect, from loan approvals to apartment applications to insurance pricing. A few things are worth understanding about how it actually works:

  • You don’t have just one score. The CFPB is direct about this: your score can differ depending on the scoring model used, the source of the underlying data, and even the day it was calculated. A mortgage lender, a credit card issuer, and the free score in a banking app may all show slightly different numbers for the exact same person.

  • The score you check yourself may not match what a lender sees. A CFPB study(opens in new window) comparing scores sold to consumers against scores sold to creditors found that roughly one in five consumers would likely see a meaningfully different number than the one a lender actually uses.

  • Payment history and utilization carry real weight. According to the FTC(opens in new window), whether bills have been paid on time and how close a balance sits to its credit limit are two of the factors that show up across most scoring systems, alongside length of credit history and recent credit applications.

What credit score means for newcomers and immigrants

Many immigrants arrive with no U.S. credit score at all, not because of any financial irregularity, but simply because a credit score is calculated from a credit report that doesn’t yet exist for them here. A strong repayment history built up over years in another country generally doesn’t carry over, since U.S. credit history doesn’t transfer from other countries(opens in new window). Because credit reporting systems are primarily national, lenders in a new country generally cannot access or verify foreign records. Consequently, starting over from zero is standard for newcomers and is not a personal failure.

Understanding how to build credit in a new country starts with accepting that reality rather than treating it as a setback, and then focusing on the specific, gradual steps that create a credit history over time, which a score can eventually be calculated from.

First steps if you have no credit score yet

  • A starter credit product, such as a secured credit card(opens in new window), can be a practical way to begin generating a credit history from scratch.

  • Paying bills on time consistently matters more than almost anything else, since payment history tends to be one of the more heavily weighted factors across scoring models.

  • A checking account in good standing can also play a supporting role in establishing a financial footprint before credit accounts exist.

  • Once a credit report exists, checking it periodically through the free resources offered by the major credit bureaus can help catch errors early.

  • Beginning in Spring 2026, eligible U.S. customers will also be able to utilize a Remitly line of credit to establish a recognized credit profile by reporting regular activity, such as sending money home, to a U.S. credit bureau.

Common questions about credit scores

  • What is considered a good credit score?

    There’s no single universal answer, since different lenders and scoring models set their own thresholds. In general, scores are viewed more favorably as they rise within the roughly 300 to 850 range. Rather than fixating on a specific number, focusing on the underlying habits, on-time payments and low utilization, tends to be more useful, as this breakdown of what counts as a good score(opens in new window) explains in more detail.

  • How long does it take to get a credit score after moving to a new country?

    This depends on how quickly a credit account is opened and used, since a score requires enough reported history to calculate. Some people see a score generated within a few months of responsible credit activity, according to Experian’s research on building credit from scratch(opens in new window), though the exact timeline varies by individual circumstance and which scoring model is used.

  • Should I pay to check my credit score?

    Not necessarily. Many banks and card issuers offer free access to at least one credit score, and the CFPB’s credit report and score resources(opens in new window) point to free annual credit reports through AnnualCreditReport.com. It’s generally worth checking whether a free option is available before paying for one.

  • Is there a way to build credit before qualifying for a traditional credit card?

    Options like secured credit cards built specifically for this purpose(opens in new window) are designed for exactly this situation, since they’re typically easier to qualify for with little or no credit history. Alternative options like certain rent-reporting services can also help build history over time, as well as upcoming options like the Remitly line of credit planned for Spring 2026. Someone without a Social Security number may also need an ITIN(opens in new window) before certain products are available at all.

In Summary

A credit score is a prediction built from a credit report, and understanding that there isn’t just one score, and that it starts from nothing for most newcomers, removes some of the mystery around the process. Building a credit history through consistent, responsible activity is the real work; the score follows from that. Understand your options as you begin building a credit history in a new financial system.
