When you apply for a loan or credit card, the bank pulls your credit report from one or more of the three national credit bureaus and runs the data through a scoring model, most commonly FICO, to produce a three-digit number between 300 and 850.1myFICO. Understanding FICO Scores That number, together with the account-by-account history behind it, is how banks check your credit and decide whether to approve you and at what interest rate. Knowing what they retrieve, how they weigh it, and what rights you have during the process puts you in a stronger position before you apply.
Where the Bank Gets Your Data
Banks buy your credit data from three nationwide consumer reporting companies: Equifax, Experian, and TransUnion.2Consumer Financial Protection Bureau. Companies List Each bureau builds its file independently from lenders, collection agencies, and public records, then sells that information to banks and other creditors evaluating an application.3USAGov. Learn About Your Credit Report and How to Get a Copy Some lenders report to all three bureaus, others to only one or two, so your three reports often do not match.
A bank cannot pull your file on a whim. The Fair Credit Reporting Act limits access to parties with a recognized legal reason, such as evaluating a credit application you submitted, and requires the bureaus to follow reasonable procedures to keep the data accurate.4Office of the Law Revision Counsel. 15 USC 1681 – Congressional Findings and Statement of Purpose
You can see the same reports the bank sees. Federal law entitles you to one free report per year from each bureau, and all three have permanently extended free weekly access through AnnualCreditReport.com.5Consumer Advice (FTC).

The Score Behind the Decision
Once a bank has your raw credit data, it feeds the file through a scoring algorithm to turn dozens of data points into one risk number. Standard FICO scores run from 300 to 850, though industry-specific versions such as the FICO Auto Score or FICO Bankcard Score use a broader 250-to-900 range.1myFICO. Understanding FICO Scores Lenders pick which version to use, whether FICO 8, FICO 10, or the newer FICO 10T, depending on the type of loan and their own risk appetite. VantageScore is the main alternative.
FICO 10T is worth knowing about because it uses trended data. Instead of a single snapshot, it looks at the direction of your balances and payments over at least the last 24 months. Two applicants with the same current balance can score differently if one has been paying balances down and the other has been letting them climb.6Experian.

What Banks Weigh Most Heavily
FICO builds its score from five weighted categories. The exact impact varies by individual, but the approximate weights show clearly what moves the number.7myFICO. How Are FICO Scores Calculated
- Payment history, about 35 percent. Whether you paid on time is the single biggest factor. Late payments are recorded at 30, 60, 90, and 120-plus days past due, and the later the payment, the greater the damage.8Experian. How Long Do Late Payments Stay on a Credit Report
- Amounts owed, about 30 percent. How much of your available credit you are currently using, the credit utilization ratio. Lower use signals less risk.
- Length of credit history, about 15 percent. A longer track record gives the bank more data to judge you on.
- New credit, about 10 percent. Several recent applications or newly opened accounts in a short window can look like stress.
- Credit mix, about 10 percent. Experience with both revolving accounts (cards) and installment debt (auto loans, mortgages) shows you can handle different repayment structures.
Paid collections deserve a note here because they surprise a lot of applicants. Paying off a collection does not remove it from your report; it typically stays for seven years from the original missed payment and simply shows as “paid.” Newer models, including FICO 9, FICO 10, FICO 10T, and VantageScore 3.0 and 4.0, ignore paid collections when calculating a score. Older models like FICO 8, which many lenders still run, count them against you.9Experian. How Do I Get a Paid Collection Off My Credit Report
What a Credit Check Actually Costs Your Score
When you authorize a bank to pull your full report, that request shows up as a hard inquiry, and other lenders can see it. Hard inquiries stay on your report for up to two years but generally affect your score for only about 12 months, and in most cases they drop it by fewer than five points.10Experian. How Long Do Hard Inquiries Stay on Your Credit Report
Soft inquiries do not affect your score at all. Checking your own credit, a pre-approved offer screen, an employer background check, or a landlord review all count as soft.11TransUnion. Hard vs Soft Inquiries – Different Credit Checks Only you see them; other creditors do not.
If you are comparing offers on a mortgage, auto loan, or student loan, you do not need to worry about each application pulling your score down. Newer FICO models treat all hard inquiries for the same loan type inside a 45-day window as a single inquiry; older versions use a 14-day window.12myFICO. The Timing of Hard Credit Inquiries – When and Why They Matter Concentrate your rate shopping rather than spreading it over months.
What Else a Bank Looks At
The credit bureaus are the main source, but not the only one. If you already bank with the institution you are applying to, it will often review its own records: average checking and savings balances, overdrafts or returned items, and how you have handled any existing loans or cards there. This internal history can carry real weight on borderline applications.
Banks also use specialty reporting agencies. ChexSystems tracks deposit-account problems such as bounced checks, unpaid fees, and suspected fraud, rather than borrowing history. A negative ChexSystems record can block a new checking or savings account even when your credit score looks strong.
For applicants with a thin credit file, some lenders consider alternative data: verified rent payments, utility bills, and bank account activity. Both FICO and VantageScore can factor in rental payment data when it is available, and programs that report on-time rent to the bureaus are becoming more common. Alternative data is typically included only if you opt in.
Your Rights When a Bank Runs Your Credit
Federal law protects you at each stage, from the pull itself through whatever decision comes out of it.
If You Get Denied or Offered Worse Terms
If a bank denies your application, offers less favorable terms than you asked for, or takes any other negative action based on your credit report, it has to send you a written adverse action notice within 30 days.13Consumer Financial Protection Bureau. Regulation 1002.9 – Notifications The notice must identify the credit bureau that supplied the report, state that the bureau did not make the decision, tell you that you can request a free copy of the report within 60 days, tell you about your right to dispute inaccurate information, and include your credit score if one was used.14Federal Trade Commission. Using Consumer Reports for Credit Decisions – What to Know About Adverse Action and Risk-Based Pricing Notices
If You Spot an Error
You can file a dispute directly with the bureau that is reporting the item. The bureau generally has to investigate within 30 days and tell you the results within five business days of finishing. If you filed the dispute after pulling your free annual report, the investigation window stretches to 45 days.15Consumer Financial Protection Bureau. How Long Does It Take to Repair an Error on a Credit Report If the investigation results in a correction, the bureau owes you a free updated copy of your report.16Federal Trade Commission. Disputing Errors on Your Credit Reports
If You Want to Control Access
A credit freeze blocks new creditors from seeing your report at all, which prevents anyone from opening accounts in your name. Placing and lifting a freeze is free under federal law. If you request it online or by phone, the bureau has to place the freeze within one business day and lift it within one hour.17Consumer Advice (FTC). Free Credit Freezes and Year-Long Fraud Alerts Are Here You will need to lift it temporarily when you want to apply for credit yourself.
A fraud alert is the lighter option. It does not block access; it requires creditors to take reasonable steps to verify your identity before extending new credit. An initial fraud alert lasts one year and can be renewed.18Consumer Advice (FTC). Credit Freezes and Fraud Alerts
