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 translate to better loan terms, lower interest rates, and broader access to financial products. Understanding what a credit score is and what affects it gives consumers a clearer picture of where they stand and what may be worth addressing.
One factor that often goes unexamined: whether a credit report contains errors that may be suppressing the score. According to the FTC (2021), 1 in 5 consumers have identified errors on their credit reports. Credit Saint reviews reports across all three bureaus — Equifax, Experian, and TransUnion — and, with your authorization, may challenge inaccurate or unverifiable entries. We’ve guarded the credit of 250,000+ Americans since 2007. We’ve got this.

A credit score is a numerical rating of financial reliability generated from the data in a consumer’s credit report. The most widely used model is the FICO Score, which ranges from 300 to 850. The higher the score, the more financially trustworthy a borrower appears to lenders. FICO scores are used by the vast majority of top lenders when making credit decisions.
Credit scores influence a wide range of financial outcomes, including:
Because credit scores affect so many financial decisions, understanding what drives them — and whether a report is accurately reflecting the consumer’s history — matters more than many people realize.
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 older accounts — even unused ones — can reduce average account age and may affect the score.
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.
Consumers are entitled to a free copy of their credit report from each of the three major bureaus — Equifax, Experian, and TransUnion — on a regular basis through AnnualCreditReport.com. Many credit card issuers and financial institutions also provide free score monitoring tools.
