What Is a Credit Score and Why It Matters

A credit score is a three-digit number, typically ranging from 300 to 850, that reflects your creditworthiness based on your financial history. Lenders use it to assess the risk of lending to you, influencing loan approval and terms.

  • Key Components of a Credit Score (FICO model):
    • Payment History (35%): Timely payments boost your score; missed payments can lower it by 50-100 points, per 2025 Experian data.
    • Credit Utilization (30%): The ratio of credit card balances to limits; keep it below 30% for optimal scoring.
    • Length of Credit History (15%): Longer histories improve scores.
    • Credit Mix (10%): Managing various credit types (e.g., cards, loans) helps.
    • New Credit (10%): Multiple recent applications can signal risk, lowering your score.
  • Impact on Loans:
    • Higher scores (670+) secure lower interest rates (7-12% APR) and larger loan amounts.
    • Lower scores (below 580) often lead to bad credit loans with APRs of 20-100%, per 2024 Federal Reserve data.
    • Example: Maria, with a 720 score, gets a $10,000 loan at 8% APR, paying $1,583 in interest over 3 years. John, with a 550 score, gets 25% APR, paying $4,429—a $2,846 difference.

How Credit Scores Affect Loan Approval

Lenders use credit scores to determine eligibility, with stricter requirements for standard loans than bad credit loans.

  • Approval Thresholds:
    • Prime Loans (670-850): Qualify for most loans with competitive rates and terms.
    • Near-Prime (620-669): May qualify for standard loans but with higher rates (12-20% APR).
    • Subprime (300-619): Limited to bad credit loans, with higher rates and fees due to perceived risk.
    • Example: Emma, with a 600 score, is denied a bank loan but qualifies for a bad credit loan at 30% APR, costing $2,372 in interest on a $4,000 loan over 3 years.
  • Other Factors:
    • Income: Lenders verify income to ensure repayment ability. A low score may require higher income proof.
    • Debt-to-Income (DTI) Ratio: Lenders prefer a DTI below 36%. For example, with $3,000 monthly income, keep debt payments under $1,080.
    • A 2025 CFPB report noted that 22% of subprime borrowers were denied loans due to high DTI ratios despite qualifying credit
