Your credit score is a three-digit number that affects more of your life than you probably realize. It determines your mortgage interest rate (difference of tens of thousands of dollars), whether you get approved for that apartment, your car insurance rate, and even whether some employers will hire you. Yet most Americans have no idea how it works or how to improve it.

What Is a Credit Score?

It's a number between 300-850 that represents how likely you are to repay borrowed money. Lenders use it to decide whether to lend to you and what interest rate to charge.

  • 800-850: Exceptional โ€” best rates on everything
  • 740-799: Very Good โ€” excellent rates
  • 670-739: Good โ€” average rates
  • 580-669: Fair โ€” higher rates, some denials
  • 300-579: Poor โ€” high rates, frequent denials

The 5 Factors (and How Much Each Matters)

  1. Payment History (35%): Do you pay on time? The biggest factor. ONE late payment can drop your score 50-100 points.
  2. Credit Utilization (30%): How much of your available credit are you using? Keep it under 30% (under 10% is ideal). If you have a $10,000 limit, keep your balance under $3,000.
  3. Length of Credit History (15%): How long have your accounts been open? Don't close old credit cards โ€” they help this factor.
  4. Credit Mix (10%): Having different types of credit (credit card, car loan, student loan) helps slightly.
  5. New Credit (10%): Too many new applications in a short period hurts your score temporarily.
๐Ÿ’ก Pro Tip: The fastest way to boost your score: pay down credit card balances to under 10% of your limit AND set up autopay for at least the minimum payment on every account. These two actions address 65% of your score (utilization + payment history).
