Your Credit Score Explained: What Actually Matters

The five factors that determine your score, which ones to prioritize, and myths that waste your time.

Your credit score affects mortgage rates, car loans, apartment applications, and even job offers. Understanding what drives it gives you the power to improve it strategically.

The Five Factors

  • Payment History (35%): Pay every bill on time, every time. One missed payment can drop your score 100+ points. Set up autopay for minimums at the very least.
  • Credit Utilization (30%): How much of your available credit you're using. Keep it below 30%, ideally below 10%. If you have a $10,000 limit, keep your balance under $1,000.
  • Length of History (15%): Older accounts help. Don't close your oldest credit card even if you rarely use it.
  • Credit Mix (10%): Having different types of credit (cards, auto loan, mortgage) helps slightly. Don't take on debt just for this.
  • New Inquiries (10%): Each hard inquiry drops your score 5-10 points temporarily. Avoid applying for multiple cards in a short period.

Quick Wins

Request credit limit increases (without spending more). Become an authorized user on a parent's old card. Dispute any errors on your credit report — 34% of reports contain mistakes.

Myths to Ignore

Checking your own score doesn't hurt it. Carrying a balance doesn't help (pay in full every month). Closing cards hurts more than it helps. You don't need to pay for credit monitoring — use free services.
