Ever wondered what that three-digit number on your credit report really means? Understanding what a credit score is, and what affects it, is the first step toward stronger financial footing.
A credit score is a three-digit number that summarizes your creditworthiness based on the information in your credit report. Lenders use it to assess the risk of extending credit. A higher score typically signals lower risk, which may mean better loan terms, lower interest rates and more financial products to choose from.
Understanding what a credit score is and what affects it gives you a clearer picture of where you stand and what may be worth addressing.
One factor that often goes unexamined is whether your credit report contains errors that may be holding your score down. In a 2013 FTC study, one in four consumers identified errors on their credit reports that might affect their credit scores.

Credit scores influence a wide range of financial outcomes, including:
Because credit scores affect so many financial decisions, it matters to understand what drives them and whether your report accurately reflects your history.
Credit scores are calculated from several categories of information, each weighted by its relative importance to the scoring model. Here is how the FICO Score breaks down:
Payment history is the single most heavily weighted factor. It reflects whether accounts have been paid on time. Late payments, collections, bankruptcies, and foreclosures can significantly affect a score. A consistent record of on-time payments, by contrast, builds a strong positive foundation over time.
Credit utilization measures how much of available credit is currently in use. It is expressed as a ratio. For example, a $3,000 balance on a $10,000 limit represents 30% utilization. Lower utilization ratios are generally associated with stronger scores. High utilization may signal over-reliance on credit to lenders reviewing the report.
The longer credit accounts have been open and active, the more data the scoring model has to work with. A longer history of responsible credit management tends to support a stronger score. Closing an older account, even an unused one, can lower your available credit, and once it eventually drops off your report, your history can look shorter.
Scoring models consider the variety of credit types on a report. A mix of revolving accounts (such as credit cards) and installment accounts (such as mortgages or auto loans) may reflect more experience managing different forms of credit.
Each formal credit application typically generates a hard inquiry on the credit report, which may cause a small, temporary score reduction. Opening several new accounts in a short period can be viewed as a signal of elevated borrowing risk by some scoring models.
You can get a free copy of your credit report from each of the three major bureaus, Equifax, Experian and TransUnion, every week through AnnualCreditReport.com. Many credit card issuers and financial institutions also provide free score monitoring tools.
When reviewing a credit report, it is worth looking for:
The Consumer Financial Protection Bureau (CFPB) provides guidance on reading credit reports and understanding consumer rights under the FCRA.
A credit score is a three-digit number lenders use to judge credit risk, and it can shape loan approvals, interest rates and even rental applications.
Payment history and credit utilization carry the most weight. Check your free reports from all three bureaus, and if an entry looks inaccurate, incomplete or unverifiable, you have the right to dispute it under the FCRA.
