The American credit scoring system is unique in the world — a three-digit number that affects nearly every major financial decision you'll make. Unlike many countries where payment history is more informal, the US uses a standardized FICO model that lenders rely on heavily.

What goes into your FICO score

FactorWeightWhat it means
Payment history35%Every late payment matters, especially recent ones
Credit utilization30%How much of your available credit you're using
Length of credit history15%Older accounts help; closing old cards hurts
Credit mix10%Having both revolving and installment credit helps
New credit inquiries10%Hard pulls temporarily lower score ~5 points

The fastest ways to improve your score

  1. Pay down credit card balances. Utilization below 10% is ideal. Even getting from 50% to 30% can add 20-40 points quickly.
  2. Never miss a payment. Set up autopay for minimums on every account. One 30-day late payment can drop your score 60-110 points.
  3. Don't close old accounts. Even if you don't use a card, keeping it open maintains average account age and available credit.
  4. Ask for a credit limit increase. Higher limit + same balance = lower utilization = higher score. Call your card issuer annually.
  5. Become an authorized user. If a family member has a long, clean credit history, being added as an authorized user can add years of history to your report.
