How to Check Your Credit Score: Where Scores Come From and What They Show

Last updated October 7, 2026 · 1,156 words · Credit Checks

Checking a credit score means reading a number produced when a scoring model evaluates the data in a credit file. Most credit scores, including FICO and VantageScore, use a range of 300 to 850. Free scores are available through many banks, card issuers, and credit reporting agency education sites.

Key takeaways

Most credit scores, including FICO and VantageScore, use a range of 300 to 850.
A credit score is calculated from data in a file held by Equifax, Experian, or TransUnion, and different models or versions can produce different numbers from the same file.
Under the FCRA, consumers have the right to a free credit report from each nationwide agency every 12 months, and the three agencies currently provide free reports weekly through AnnualCreditReport.com.
FICO's published approximate weights are payment history 35%, amounts owed 30%, length of credit history 15%, new credit 10%, and credit mix 10%, while VantageScore does not publish fixed percentages.
Hard inquiries typically remain on a credit report for 2 years, and most negative information, including late payments, stays for 7 years.
Free scores from banks, card issuers, and agency education sites are real scores from real models, but they may not be the model or version a specific lender uses.

Where a credit score comes from

Equifax, Experian, and TransUnion are the three nationwide credit reporting agencies. Each maintains a file containing a consumer's accounts, balances, payment history, collection items, and inquiries. A scoring model — most often FICO or VantageScore — reads that file and calculates a number. The model, the version of that model, and the file it reads all shape the result, which is why two sources can show two different numbers on the same day. The Consumer Financial Protection Bureau explains that the score a consumer sees may come from a different model or version than the one a particular lender uses.

What a score describes is consistent regardless of source: how the data in a file compares with the patterns a model associates with repayment over time. The score is an output, not a record. The underlying details — account statuses, limits, balances, dates — remain in the credit report itself.

Aggregate lending activity is tracked separately. The Federal Reserve's G.19 release reports total outstanding consumer credit for the economy as a whole, a figure that describes the market rather than any individual file.

Ways consumers can see a credit score at no cost

Free access to a score generally arrives through one of a few channels. Most do not require a paid subscription, though some providers bundle a free score with paid products.

Financial institutions. Many banks, credit unions, and credit card issuers display a score to account holders, often refreshed monthly.
Credit reporting agency education sites. Agencies publish public material about how scores work and, in some cases, provide access to a score. Experian's credit education pages are one example of that kind of public resource.
Nonprofit counseling organizations. Nonprofit credit counseling agencies often review a score with a consumer as part of a session.
Services built around federal report rights. The free file disclosures available under federal law supply the underlying report data, and some services pair that data with a score.

Free file disclosures and free score access are separate matters. Federal law guarantees free credit reports from each nationwide agency; a score is not automatically attached to that disclosure. Some scores are labeled educational, a term that describes which model or version produced the number rather than whether the number is genuine.

How scores are calculated

FICO publishes approximate weights for the factors it considers. VantageScore uses its own weighting and does not publish fixed percentages.

Factor	Approximate weight in FICO scores
Payment history	35%
Amounts owed	30%
Length of credit history	15%
New credit	10%
Credit mix	10%

Every factor describes data already present in the file: whether payments arrived on time, how balances compare with credit limits, how long accounts have been open, how many new accounts or inquiries appear recently, and whether the file contains both revolving and installment accounts. A fuller walkthrough sits in how credit scores are calculated, and the differences between the two major models are covered in FICO vs. VantageScore.

Checking a credit report alongside a score

A score summarizes a file; the file contains the details. The Fair Credit Reporting Act, enacted in 1970 and amended by the Fair and Accurate Credit Transactions Act in 2003, gives consumers the right to a free credit report from each nationwide agency every 12 months. The three agencies currently provide free reports weekly through AnnualCreditReport.com, as described by the Federal Trade Commission.

Reading the file shows what a score is summarizing, including:

Account names, statuses, balances, and credit limits.
Month-by-month payment history, including late payments.
Collection accounts and public records such as bankruptcies.
Inquiries from lenders that requested the file.
Identifying information and any addresses that do not belong there.

Most negative information, including late payments, stays on a credit report for 7 years. A Chapter 7 bankruptcy stays for 10 years, a Chapter 13 bankruptcy for 7 years, and hard inquiries typically remain for 2 years. Under the FCRA, a credit reporting agency generally must investigate a dispute within 30 days, and that period can extend to 45 days if the consumer provides additional information during the initial 30-day window.

The report side of the process is covered at credit reports, and the broader routine of reviewing a file is described at credit checks. The Consumer Financial Protection Bureau was created by the Dodd-Frank Act in 2010 and began operating in 2011; it publishes consumer resources about both reports and scores.

Why two sources can show different scores

Differences usually trace to one of four causes:

The model. FICO and VantageScore weigh the same categories of data differently.
The version. Both companies release updated versions, and lenders adopt them at different times.
The agency. A lender may report an account to one agency and not another, so the three files are not identical.
The date. Balances and inquiries change as statements post, so a score from last week is not a score from today.

None of these means a score is inaccurate. Each number reflects one model reading one file at one point in time.

Scores, ranges, and what a number does not describe

Score ranges vary by model, and most consumer-facing scores, including FICO and VantageScore, run from 300 to 850. A number inside that range does not describe a lender's decision, because each lender sets its own criteria and may weigh information beyond a score. The bands that some providers use to label scores are their own. A general overview is at credit score ranges explained, and how balances enter the calculation is covered in credit utilization explained. The broader concept of a score and its inputs is outlined at credit score.

Protecting access to a credit file

Because a credit file drives the score, access controls matter. Under FCRA section 605A (15 U.S.C. section 1681c-1), an initial fraud alert lasts 1 year and an extended fraud alert lasts 7 years. Under section 605B (15 U.S.C. section 1681c-2), a consumer who files an identity theft report can request that fraudulent information be blocked from the file. A security freeze is free to place, temporarily lift, or remove under federal law. Details are at credit freezes, and steps for a compromised file are at identity theft. Identity theft can be reported at IdentityTheft.gov and to the IRS using Form 14039.

Monitoring services, described at credit monitoring, watch for changes such as new inquiries or new accounts. They observe the same data that feeds a score; they do not set the score or determine what a lender decides.

Frequently asked questions

Can you check your credit score for free?

Yes. Many banks, credit unions, credit card issuers, credit reporting agency education sites, and nonprofit counseling organizations provide a score at no cost. Score access is separate from the free credit report right, which guarantees a free report from each nationwide agency every 12 months; the three agencies currently provide free reports weekly through AnnualCreditReport.com.

Does checking your own credit score affect it?

A request a consumer makes for their own report or score is treated as a soft inquiry. Hard inquiries come from lenders evaluating an application, and those typically remain on a credit report for 2 years. Scoring models distinguish between the two types of inquiries.

What score range do FICO and VantageScore use?

Most credit scores, including FICO and VantageScore, use a range of 300 to 850. Some specialized or industry-specific models use different ranges, and lenders set their own criteria for the scores they review.

Why is my credit score different at two different places?

Scores can differ because of the model used, the version of that model, the credit reporting agency whose file is read, and the date the score was calculated. A lender does not have to report an account to all three agencies, so the three files are not identical, and balances change as statements post.

Is a credit score the same thing as a credit report?

No. A credit report is the record of accounts, balances, payment history, inquiries, and public records held by a credit reporting agency. A credit score is a number calculated from that record by a scoring model such as FICO or VantageScore.

Does the free credit report come with a free credit score?

Not necessarily. The Fair Credit Reporting Act guarantees free credit reports from each nationwide agency every 12 months, and the agencies currently provide them weekly through AnnualCreditReport.com. A score is not automatically included with that disclosure; score access usually comes through a bank, card issuer, agency education site, or counseling organization.
