Understanding Your Credit Score (and How to Improve It)
What a credit score measures, what the scoring models weigh, how long negative items stay on your report, and the slow, legal ways to raise a score.
Key points
- A credit score is a prediction of how likely you are to repay on time, calculated from your credit reports. You have many scores, and most run from 300 to 850.
- Paying on time and keeping card balances low relative to your limits carry the most weight in both FICO and VantageScore models.
- You can check your reports at all three bureaus for free every week at AnnualCreditReport.com, and dispute errors for free.
- Most negative items can stay for seven years and bankruptcy for ten. No company can legally remove accurate information before then.
A credit score is a three-digit summary of your credit reports, built to predict one thing: how likely you are to pay a debt back on time. Lenders use it to decide whether to approve you and at what price, and some landlords and insurers look at credit information too. Raising a score is possible, but the methods that work are slow and ordinary, and there are no legal shortcuts.
What a credit score is, and why you have several
The CFPB describes a credit score as a prediction of your credit behavior based on the information in your credit reports. You don't have just one. FICO and VantageScore each sell several models and versions, and each can be calculated from your report at Equifax, Experian or TransUnion, which rarely hold identical information. Most scores run from 300 to 850.
That is why the number on a banking app and the number a lender sees can differ by several points without anything being wrong. What moves them all in the same direction is the content of your reports.
What goes into the score
Both main scoring companies publish what their models weigh. The figures differ, but the order of importance is similar: whether you pay on time comes first, and how much of your available credit you use comes second.
| Factor | FICO Score | VantageScore 4.0 |
|---|---|---|
| Payment history | 35% | 41% |
| How much you owe | 30% (amounts owed) | 20% (utilization) and 6% (balances) |
| Length and depth of history | 15% | 20% (depth of credit) |
| New credit and recent applications | 10% | 11% (recent credit) |
| Mix of credit types | 10% | Part of depth of credit |
| Available credit | Part of amounts owed | 2% |
FICO weights are for the general population; for any one person the importance of each category can differ. VantageScore weights from its consumer guide published June 26, 2025. Source: myFICO.com; VantageScore.
FICO puts payment history at 35% and amounts owed at 30%, followed by length of history, new credit and credit mix. VantageScore's guide gives payment history 41% in its 4.0 model. Notice what is missing from both lists: your income, your savings and your job. A score measures how you handle credit, not how much money you have.
Start with your credit reports
Everything in the score comes from your credit reportThe record a credit bureau keeps about your accounts, balances, payments, collections and credit applications. Scores are calculated from it., so that is where to begin. The three bureaus have permanently extended free weekly reports at AnnualCreditReport.com, the site the FTC points to. Checking your own report doesn't affect your score. A report is not a score, but it is the part you can check and correct.
Errors are not rare. In a 2012 study of 1,001 people, the FTC found that one in five had an error on at least one of their three reports that the bureau corrected after a dispute. The study is old, but the lesson still holds: look at all three reports, not one.
If something is wrong, dispute it in writing with the bureau and with the company that reported it, and include copies of documents that support you. The bureau generally has 30 days to investigate, which the law allows to be extended by up to 15 days if you send new information during that time. Disputing is free.
How long negative information stays
Accurate negative information doesn't stay forever, but it stays a long time. The Fair Credit Reporting Act lets bureaus report most negative items for seven years and bankruptcies for ten.
| Item | How long | Where the rule comes from |
|---|---|---|
| Late payments and most other negative items | 7 years | Fair Credit Reporting Act |
| Accounts sent to collection or charged off | 7 years, counted from 180 days after the delinquency began | Fair Credit Reporting Act |
| Bankruptcy | Up to 10 years from the order for relief | Fair Credit Reporting Act |
| Paid medical collections | Not reported | Bureaus' own policy since July 1, 2022 |
| Medical collections first reported under $500 | Not reported | Bureaus' own policy since April 11, 2023 |
| Unpaid medical collections | Not reported for the first year | Bureaus' own policy |
| Accounts paid as agreed | Can stay longer than negative items | No federal time limit |
The medical debt rows are voluntary policies of Equifax, Experian and TransUnion, not federal law.
Medical debt is treated differently because of the bureaus' own choices. Since 2022 and 2023, Equifax, Experian and TransUnion no longer report paid medical collections or those first reported under $500, and they wait a year before showing unpaid ones. A broader federal rule that would have removed medical debt from reports was vacated by a federal court on July 11, 2025, so it never took effect.
The good news in the timeline: the effect of an old late payment on a score fades well before it leaves the report, provided the newer history is clean.
How to improve a score
There is no trick here, only habits the models reward.
Pay every bill on time. Payment history carries the most weight in both models. If you tend to forget, set up automatic payments for at least the minimum on every card and loan, then pay more by hand.
Keep card balances low. Your utilizationHow much of your available card credit you are using: the total of your card balances divided by the total of your card limits. is the second biggest factor. The CFPB notes that experts advise using no more than 30 percent of your total credit limit. If you carry balances on several cards, paying down the one closest to its limit lowers both that card's ratio and your total.
Apply for new credit only when you need it. A hard inquiryA check of your credit file by a lender after you apply for credit. It can lower some scores for a while. Checking your own report is a soft inquiry and doesn't. happens when a lender reviews an application. When you shop for a single mortgage, auto or student loan, FICO's newer models count inquiries within any 45-day span as one, and older versions within 14 days; VantageScore uses 14 days. Shopping for several credit cards gets no such allowance.
Let old accounts age. Length of history counts, and it only grows with time. Closing your oldest card can shorten it eventually and lowers your total available credit right away.
If you have little or no history, start small. The CFPB describes secured cards and credit builder loans as ways to establish credit: with a secured card you put down a deposit, for example $500, and can spend up to that amount. Ask whether the issuer reports to all three bureaus, because a card that doesn't report builds nothing. Being added as an authorized user on a family member's card is another route; you can use the card but are not legally responsible for the bill.
Protect your file
A credit freezeA block that stops a bureau from sharing your report with new lenders until you lift it. Placing and lifting it is free. stops new lenders from seeing your report, which makes it much harder for someone to open credit in your name. The FTC confirms there is no cost to place or lift a freeze; you place it separately at each of the three bureaus and lift it for a lender when you apply. A fraud alert is a lighter option: an initial alert lasts one year, and an extended alert for identity theft victims lasts seven.
Be wary of credit repair companies
Credit repair companies promise what the law doesn't allow them to deliver. Under the Credit Repair Organizations Act they cannot charge you before the service is fully performed, the contract must be in writing, and you can cancel without penalty before midnight of the third business day after signing. The FTC puts it plainly: anything such a company can do legally, you can do yourself for little or no cost. We wouldn't pay anyone to dispute items you can dispute for free.
What is changing
Scoring is not standing still. For mortgages sold to Fannie Mae and Freddie Mac, the FHFA opened the use of VantageScore 4.0 to all approved lenders on September 9, 2026, alongside Classic FICO; FICO 10T is not yet eligible there. Buy now, pay later loans are another moving piece: FICO announced BNPL-inclusive versions of its scores in June 2025, but, as myFICO explains, BNPL data can affect a FICO Score only if it appears in your credit file at a bureau.
What to consider before you apply for new credit
-
Have you seen your reports in the last few months?
Check all three bureaus before a large application such as a mortgage or car loan. Errors take time to correct, and a dispute can take a month or more.
-
Is this application worth the inquiry?
Each new application usually means a hard inquiry and, if approved, a younger average account age. Neither is serious on its own, but several in a short time can add up.
-
Are you rate shopping or opening several accounts?
Shopping for one mortgage, auto or student loan within a short window is treated differently from applying for several cards. Keep your loan shopping close together.
-
Would the new account change your utilization?
A new card raises your total limit, which can lower utilization. It also invites spending, which raises it. Be honest about which one is likely.
Questions to ask before you sign
Whether you are applying for credit or paying for a credit-related service, ask these first:
- Which credit score model and which bureau will you use to decide on my application?
- Is checking my rate a soft inquiry, and at what step does a hard inquiry happen?
- Do you report my account to all three bureaus, and how often?
- For a secured card: how much is the deposit, when and how can I get it back, and is there an annual fee?
- For a credit builder loan: what is the APR, what fees apply, and when do I receive the money?
- For any credit repair or monitoring service: what exactly will you do that I cannot do myself for free, what does it cost in total, and where is my written right to cancel?
- If I am denied, which report and which score did you use, and how do I get a free copy of that report?
Common questions
Does checking my own credit lower my score?
No. Requesting your own reports is a soft inquiry. Only hard inquiries, made when a lender reviews an application for credit, can affect a score.
Why is my score different on different apps?
Because there isn't one score. Each score depends on the model, its version and which bureau's report it uses. A lender may use a different one from the app you check.
Will paying off a collection remove it from my report?
For medical collections, the three bureaus remove them once paid. For other collections, paying usually changes the status to paid, but the account can remain for up to seven years.
Should I close old credit cards I don't use?
Closing a card removes its limit from your total, which can raise utilization, and over time can shorten your history. If the card has no annual fee, keeping it open and using it now and then is usually the simpler choice.
Can a credit repair company remove accurate negative information?
No. The FTC says anything a credit repair company can do legally, you can do yourself for little or no cost. Accurate information can stay on your report for the periods set by law.
