What Is a Credit Score?

A credit score is a three-digit number that represents how likely you are to repay borrowed money. Lenders use it to decide whether to approve applications and what terms to offer.

Credit scores are calculated using information from your credit reports, including your payment history, balances, account age, and recent activity.

Credit Score Ranges Explained

Score Range	Category	What It Means
300–579	Poor	Limited options, higher risk to lenders
580–669	Fair	Some approvals, higher interest rates
670–739	Good	Most approvals at reasonable terms
740–799	Very Good	Better rates and more flexibility
800–850	Excellent	Best rates and strongest profiles

What Affects Your Credit Score the Most

Payment history: On-time vs late payments
Credit utilization: Balances compared to limits
Length of credit history: Age of accounts
Credit mix: Cards, loans, and installment accounts
New credit: Recent applications and inquiries

Important: Payment history and utilization usually have the biggest short- and long-term impact.

Credit Score Models: FICO vs VantageScore

There are multiple scoring models, but the most common are FICO® and VantageScore®. Lenders may use different versions depending on the situation.

FICO: Most widely used by lenders
VantageScore: Often used for free credit monitoring

Scores may vary slightly depending on the model and which credit bureau is used.
