What Is a Credit Score?
A credit score is a number calculated from information in a person’s credit report. It is designed to estimate repayment risk based on patterns reflected in credit data. Credit scores do not measure income, savings, or personal character — they summarize credit-related information.
Organizations may use credit scores as one factor when evaluating applications (for example, certain types of loans, rental applications, or other services). Different organizations may use different scoring models.
How Credit Scores Relate to Credit Reports
A credit score is calculated using data from a credit report. Credit reports typically include payment history, account balances, loan amounts, credit limits, account age, and recent inquiries. The score is a mathematical interpretation of that information.

Common Credit Scoring Models
There is no single credit score. Two commonly referenced scoring models are FICO® Score and VantageScore®. Both generally consider similar categories of information but may weigh them differently. As a result, it’s possible to have multiple scores at the same time.
Lenders may also use different versions of a scoring model depending on the type of credit being evaluated (for example, mortgage, auto loans, or credit cards).
Typical Credit Score Ranges
Many commonly used scoring systems range from 300 to 850. Ranges can vary by model, but they are often grouped into broad categories such as:
- 300–579: Poor
- 580–669: Fair
- 670–739: Good
- 740–799: Very Good
- 800–850: Excellent
These ranges are general guidelines and may differ by scoring model or lender.
What Factors Typically Affect a Credit Score?
Scoring formulas are proprietary, but models generally evaluate similar categories of credit information. Below are common factors that may influence a score.
Payment history
Whether accounts are paid on time. Late payments, collections, and charge-offs may negatively affect scores.
Credit utilization
The percentage of available revolving credit currently being used (for example, credit cards). Higher utilization may affect scores differently than lower balances.
Length of credit history
How long accounts have been open and how long credit has been established.
Credit mix
The variety of account types (such as credit cards, installment loans, and mortgages).
Recent credit activity
Newly opened accounts and recent credit inquiries can be considered, especially over short periods.
Not all lenders use the same score
Different organizations may use different scoring models or versions, and may consider other factors beyond credit scores.

Misunderstandings About Credit Scores
Myth: Checking your own score lowers it
Checking your own credit score is typically a “soft inquiry” and generally does not impact your score.
Myth: Income directly affects your score
Income is not usually included in standard scoring formulas. Credit scores are generally based on credit behavior reflected in credit reports.
Myth: You only have one credit score
Many people have multiple scores depending on the scoring model, version, and the credit bureau data used.
How to Monitor a Credit Score
Consumers may review credit reports from the major credit bureaus and can monitor credit scores through various financial institutions or consumer platforms. When reviewing a score, it can also be useful to review the underlying credit report for accuracy.

Why can my score differ between sources?
Different services may use different scoring models or versions, and may use different credit bureau data.
Does closing a credit card always improve a score?
