What Is a Credit Score?

A credit score is a 3-digit number between 300 and 850 that represents your creditworthiness — how likely you are to repay debt on time. Lenders, landlords, insurers, and even some employers use credit scores to assess risk. The most widely used model in the US is the FICO Score, developed by Fair Isaac Corporation, though VantageScore (created by the three major credit bureaus) is also common. Both use similar factors and the same 300–850 scale.

The 5 FICO Factors and Their Weights

• Payment History (35%): The single most important factor. Even one 30-day late payment can drop your score by 50–110 points. Bankruptcies and collections have severe, long-lasting impacts.
• Credit Utilization (30%): The percentage of your available revolving credit you are using. Experts recommend staying below 30%, with below 10% being ideal for top scores. Utilization above 50% significantly hurts your score.
• Length of Credit History (15%): The age of your oldest account, newest account, and average age of all accounts. A longer history helps. This is why closing old credit cards (even unused ones) can hurt your score.
• Credit Mix (10%): Lenders prefer to see that you can manage different types of credit responsibly — credit cards (revolving), auto loans, mortgages, and student loans (installment). A mix is better than all of one type.
• New Credit / Inquiries (10%): Applying for new credit generates a "hard inquiry" that temporarily reduces your score by 5–10 points. Multiple applications in a short period can compound this effect.

Credit Score Ranges and What They Mean

• 800–850 (Exceptional): Access to the best interest rates and credit limits. Less than 20% of Americans achieve this range.
• 740–799 (Very Good): Above-average scores that qualify for near-best rates. A 740+ score often qualifies you for "prime" lending rates on mortgages.
• 670–739 (Good): The average American falls in this range. You qualify for most credit products, though not always at the best rates.
• 580–669 (Fair): May be approved for some credit, but at higher interest rates. FHA loans accept scores as low as 580.
• 300–579 (Poor): Significant difficulty getting approved for credit. Secured credit cards and becoming an authorized user on another's account are common first steps toward rebuilding.

How to Improve Your Credit Score

• Pay every bill on time — set up autopay for at least the minimum payment
• Pay down credit card balances to below 30% (ideally 10%) of each card's limit
• Keep old accounts open even if you don't use them
• Only apply for new credit when you need it
• Check your credit report annually at AnnualCreditReport.com for errors — each bureau (Equifax, Experian, TransUnion) must provide one free report per year
• Consider a secured credit card or credit-builder loan if you are rebuilding from poor credit
