What Is a Credit Score in the US and Why It Matters: A Simple Explanation

What is a credit score in the US, in simple words?

What is a credit score in the US? In short, it is your money reputation squeezed into one number. A credit score, or just “score” for short, is a three-digit rating from 300 to 850. It is calculated by a computer program. The program looks at how you handled debt in the past and gives you a score. The higher the number, the more you are trusted.

Imagine you are lending money to someone you know. Right away you think: did they pay me back on time last time? Did they disappear? A bank in the US does the same thing. Only instead of a memory, it has your score. Basically, it is a prediction: will this person pay the money back, and will they pay without being late?

An important detail: your score is not about how much you earn. Your salary simply is not in your credit history. You can make $10,000 a month and have a score of 580. Or you can earn a modest income and have 780, because you always pay on time and don’t take on extra debt. How the program puts your score together is explained in detail in our article about the five credit score factors.

One more thing that confuses a lot of people: you don’t have just one score, you have dozens. There are several scoring programs, and the main ones are FICO and VantageScore. Each one has several versions, and each bureau has its own data. That is where the surprises come from: your bank app shows 690, but the car dealer says 665. We explain where this difference comes from in our article on why FICO and VantageScore show different numbers.

Where is your credit score checked in the US?

The short answer: almost anywhere you use something first and pay for it later. Many newcomers only find out about this when they get turned down or are asked to pay more than other people.

A separate note about insurance. Not every state allows your credit history to be used when setting car insurance prices. For example, it is not allowed in California, Hawaii, Massachusetts and Michigan.

How much does a bad credit score cost in dollars?

A bank rarely tells you straight out, “Your score is low.” More often, it just gives you a higher interest rate. And you overpay every month, for years. The easiest way to see what your score costs is to do the math.

With a mortgage, the amounts are even bigger, because the loan is larger and longer. Again, hypothetically: $400,000 for 30 years at 6.5% means a payment of about $2,528 a month. At 7.5%, it is already about $2,797. Just one percentage point of difference, and you pay almost $270 extra every month, or about $97,000 over 30 years.

A low score also means deposits for electricity and phone service, expensive insurance (where that is allowed) and denied credit card applications. Each amount on its own is small, but together they add up.

What credit score is considered good in the US?

FICO, the most widely used scoring program in the US, has official ranges. Here they are in plain words, with what each one means in practice.

• 300–579, poor. You will be turned down for most regular cards and loans. That leaves secured cards (cards where you put down a deposit) and high-interest loans.
• 580–669, fair. You may get approved, but it costs more: a higher rate, a lower limit (how much you are allowed to spend on the card), and sometimes you are asked for a deposit or a co-signer.
• 670–739, good. Most cards and loans are available on normal terms.
• 740–799, very good. Banks are happy to offer low rates and good limits.
• 800–850, exceptional. You are in the best group. Beyond this point, a higher number barely changes your terms.

The line for “good” is 670. But every bank has its own rules. One card will approve someone with 650, while another wants to see 720 or higher. So the number is a guide, not a final verdict.

Are a credit report and a credit score the same thing?

No, they are two different things. A credit report is a detailed file about you. It shows what cards and loans you have, what your limits are, how much you owe, whether you paid on time and who has asked to see your history. A credit score is one number that a program calculates from this file.

Credit reports are kept by three private companies, the credit bureaus: Experian, Equifax and TransUnion. Banks send them updated information about once a month. But not always to all three at once. That is why your reports at different bureaus can be different, and so can your scores.

The three US credit bureaus

A simple rule: your score shows what is going on with your credit, and your report explains why. If the number is low, you always look for the answer in the report. And sometimes people find errors there: someone else’s account, a wrong limit, an old late payment that should not be there anymore. We explain how to make sense of your report on your own in our guide how to read a credit report.

Is having no credit history the same as having a bad score?

No. If you are new to the US and don’t have a single credit card or loan yet, you simply don’t have a score. The program has nothing to calculate it from. It is not 300 and not zero. It is a blank space.

Excalibur Credit Solutions managers often hear the same question: “I’ve been paying with my card for two years. Why don’t I have a score?” The answer is simple: a debit card does not show up in your credit history. It spends your own money, not the bank’s money. People usually start their history with a credit card or a small loan.

But for a bank, a blank space is also a risk. It does not know how you will handle money. That is why people with no history are often turned down just like people with a bad one. The good news: building a history from scratch is usually easier than fixing a damaged one.

Your first score does not appear right away. For FICO to calculate it, you usually need at least one account that is about six months old. Your credit history from back home, whether from Russia, Ukraine or Armenia, does not automatically transfer to the US. Here, everyone starts with a clean slate. A step-by-step plan is in our article about building credit history from scratch.

What to do today: find out your score and get your three-bureau report

To understand where you stand, one number from an app is not enough. You need a report from all three bureaus, along with your scores. Here is a simple step-by-step plan.

1. Check your free score in your bank or credit card app. Many banks show it, and it gives you a quick idea of where you are.
2. Get a three-bureau report through a credit monitoring service. This is a website that shows your report and tracks what changes in it. SmartCredit, IdentityIQ or MyScoreIQ will work. Our guide about the three-bureau report shows how to do it step by step.
3. Compare your scores at the three bureaus. If the number at one of them is much lower, look for an entry that shows up only there.
4. Go through your report: are all the accounts yours, are there any late payments you did not know about, and are your limits listed correctly?
5. Write down everything that raises questions. If an entry looks like a mistake, you can ask the bureau to check it again. This is called disputing the entry. You have the right to send this request yourself, and it costs nothing.

Don’t panic if your score turned out lower than you expected. It is just a starting point. First, figure out why your number is what it is. The most common reasons are collected in our article on why a credit score can be low.

At Excalibur Credit Solutions, the review starts with exactly that: finding the reasons. A manager opens your three-bureau report together with you. In 15–20 minutes, the manager shows you which entries are pulling your score down the most and what can be done about them. The review is free. Results vary. But understanding where your number came from is already half the battle.
