Your credit score comes from the payment and borrowing history that credit bureaus collect about you

A credit score is a three-digit number that lenders use to decide whether to lend you money and at what interest rate. The score itself is calculated by credit reporting agencies — mainly Equifax, Experian, and TransUnion — based on information they gather about your borrowing and payment behavior. You do not explore for a credit score or do anything special to "get" one. Instead, a score is generated automatically once you have a credit history, which starts the moment you open a credit account or borrow money.

The score exists because lenders need a quick way to assess risk. Instead of reviewing your entire financial life, they look at a single number. That number comes from patterns in your past: whether you paid bills on time, how much debt you currently carry, how long you have been borrowing, and what types of credit you have used. The three major bureaus each maintain their own version of your history and may produce slightly different scores, which is why you can have three different credit scores at once.

Key Takeaways

  • A credit score is built automatically once you open a credit account or take out a loan — you do not need to do anything to start the process.
  • Payment history makes up the largest part of your score, so paying bills on time is the single most important factor in building credit.
  • The three major credit bureaus (Equifax, Experian, and TransUnion) each maintain separate records and may produce different scores for the same person.
  • You can request a free copy of your credit report from each bureau once per year at annualcreditreport.com, which is the official government site.
  • Credit scores typically range from 300 to 850, with higher scores making it easier and cheaper to borrow money.

What information credit bureaus use to calculate your score

Credit bureaus collect data from lenders, creditors, and public records. When you open a credit card, take out a car loan, or get a mortgage, the lender reports your account details to the bureaus. This includes your account opening date, credit limit or loan amount, current balance, and whether you pay on time. The bureaus also receive reports when you miss payments, default on a loan, or have a debt sent to a collection agency.

Public records — such as bankruptcy filings, tax liens, and court judgments — also appear in your credit file. These negative marks can significantly lower your score. The bureaus do not know your income, employment history, or savings account balances, because those details are not reported to them. A lender may ask you for that information separately, but it does not factor into your credit score itself.

The five factors that make up your credit score

Payment history is the largest component, accounting for about 35 percent of your score. This is whether you pay your bills on time. A single late payment can lower your score, and the impact is worse for recent late payments than for older ones. Payments that are 30 days late, 60 days late, or 90 days late are all reported separately, with worse consequences for longer delays.

Credit utilization makes up about 30 percent of your score. This is the percentage of your available credit that you are currently using. If you have a credit card with a $1,000 limit and a $300 balance, your utilization is 30 percent. Lower utilization is better — most scoring models reward you for using less than 30 percent of your available credit. Paying down balances can improve your score quickly because utilization changes are reported monthly.

Length of credit history accounts for about 15 percent of your score. This includes how long your oldest account has been open and the average age of all your accounts. Older accounts help your score, which is why closing old credit cards can sometimes hurt it. You do not need decades of history to have a good score, but newer borrowers typically have lower scores than people who have been borrowing for many years.

Credit mix makes up about 10 percent of your score. This is the variety of credit types you have used — credit cards, car loans, mortgages, student loans, and so on. Having different types of credit shows lenders you can manage various kinds of debt. You do not need to seek out different types of credit just to improve your score, but having a mix is better than relying on only one type.

New credit inquiries account for about 10 percent of your score. When you explore for credit, the lender checks your credit report, which is called a hard inquiry. Multiple hard inquiries in a short time can lower your score slightly. However, inquiries from rate shopping — when you explore for a mortgage or car loan with multiple lenders within a short window — are often counted as a single inquiry by scoring models. Checking your own credit report does not lower your score.

How long it takes to build a credit score

You typically need at least six months of credit history before a credit score is calculated. During those first six months, you should have at least one account open and at least one payment reported to the bureaus. Opening a credit card and making a small purchase, then paying it off on time, is one of the fastest ways to start building credit.

After six months, you will have a score, but it may be low if your history is short. Scores improve over time as you continue to pay on time and keep balances low. Negative marks like late payments or collections stay on your report for seven years, but their impact on your score decreases as they age. A late payment from five years ago hurts your score much less than a late payment from last month.

Where to find your credit score and report

You can get a free copy of your credit report from each of the three major bureaus once per year at annualcreditreport.com. This is the official government site, and it is the only place where you can get a truly free report without being asked to sign up for a paid service. The report shows all the accounts and payment history that the bureau has on file, but it does not include your credit score.

Your credit score is separate from your credit report. Many credit card companies and banks now show your score for free in your online account or mobile app. You can also purchase your score directly from the bureaus or from third-party sites that offer free scores in exchange for signing up for monitoring services. Keep in mind that free scores from different sources may not match exactly, because different scoring models exist — the most common is the FICO score, but VantageScore is also widely used.

What happens if you have no credit history

If you have never borrowed money or opened a credit account, you have no credit score. This is sometimes called being "credit invisible." Lenders cannot assess your risk because they have no data about you. To start building credit, you need to open an account that will be reported to the bureaus.

A secured credit card is often the easiest first step. You deposit money with a bank, and the bank issues you a credit card with a limit equal to your deposit. You use the card like a normal credit card, and your payments are reported to the bureaus. After six to twelve months of on-time payments, you may be able to convert it to a regular card or open other accounts. A credit-builder loan is another option — you borrow a small amount of money that the lender holds in a savings account, and you make monthly payments toward it. Once you pay it off, you get the money back, and the lender reports your payments to the bureaus.

How to improve a low credit score

The fastest way to improve your score is to pay down credit card balances. Because credit utilization makes up 30 percent of your score, lowering the percentage of credit you are using can produce results within one or two months. If you have a $5,000 balance on a card with a $10,000 limit, paying it down to $2,000 will when ready improve your utilization ratio.

The most important long-term step is to pay every bill on time, every month. Set up automatic payments if you struggle to remember due dates. If you have missed payments in the past, continue paying on time going forward — the impact of old late payments fades over time. Do not close old credit cards after paying them off, because closing accounts can lower your score by reducing your available credit and shortening your average account age. Instead, keep them open and use them occasionally.

Frequently Asked Questions

Can I get a credit score without a credit card?

Yes. Any type of credit that is reported to the bureaus can build your score — car loans, mortgages, student loans, and credit-builder loans all work. Credit cards are common because they are straightforward to open and report quickly, but they are not required. However, if you have only one type of credit, your score may be lower than if you had a mix.

Does checking my own credit score lower it?

No. Checking your own credit report or score is called a soft inquiry and does not affect your score. Only hard inquiries from lenders when you explore for credit can lower your score slightly. You can check your score as often as you want without penalty.

How long do negative marks stay on my credit report?

Late payments, collections, and charge-offs typically stay on your report for seven years from the date of the first missed payment. Bankruptcy stays for seven to ten years depending on the type. Tax liens and judgments may stay longer. Even after seven years, the mark may still appear on your report but will have much less impact on your score.

What is a good credit score?

Credit scores range from 300 to 850. Scores above 670 are generally considered good, and scores above 740 are considered very good. Lenders set their own standards, so the score you need depends on what you are borrowing for. A mortgage lender may require a score of 620, while a credit card company might require 700.

Can I have different credit scores from different bureaus?

Yes. Each bureau maintains its own file and may have slightly different information, which results in different scores. Lenders may report to all three bureaus, some, or just one. Your scores from Equifax, Experian, and TransUnion can vary by 50 points or more. When you explore for credit, the lender typically uses the score from one specific bureau.
