FICO® Credit Scores
A FICO® Score is a proprietary credit score created by the Fair Isaac Corporation (FICO). About 90% of top U.S. lenders use it to make lending decisions.
FICO® Score Ranges:
- Exceptional: 800–850
- Very Good: 740–799
- Good: 670–739
- Fair: 580–669
- Poor: 300–579
FICO categorizes scores as Poor, Fair, Good, Very Good, and Exceptional.
What is a Credit Score?
A credit score is a three-digit number (300–850) predicting your creditworthiness. Lenders use it to evaluate risk and determine rates and terms for credit.
Why it matters: A higher score can help you qualify for loans and lower interest rates. A lower score can lead to higher borrowing costs or application denials.
FICO® Credit Score Facts
- Three-Digit Number: Summarizes your credit risk.
- Range: 300–850; higher scores = lower risk.
- Data Source: Uses your credit reports from Experian, Equifax, and TransUnion.
- Industry Standard: Lenders rely on FICO for mortgages, auto loans, and credit cards.
Note: Credit scores reflect your creditworthiness but do not guarantee approval for any credit product.
Security Notice: All participating issuers use secure application systems protected by Transport Layer Security (TLS) encryption to help protect your information.
