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
| Factor | Weight | What it means |
|---|---|---|
| Payment history | 35% | Every late payment matters, especially recent ones |
| Credit utilization | 30% | How much of your available credit you're using |
| Length of credit history | 15% | Older accounts help; closing old cards hurts |
| Credit mix | 10% | Having both revolving and installment credit helps |
| New credit inquiries | 10% | Hard pulls temporarily lower score ~5 points |
The fastest ways to improve your score
- Pay down credit card balances. Utilization below 10% is ideal. Even getting from 50% to 30% can add 20-40 points quickly.
- Never miss a payment. Set up autopay for minimums on every account. One 30-day late payment can drop your score 60-110 points.
- Don't close old accounts. Even if you don't use a card, keeping it open maintains average account age and available credit.
- Ask for a credit limit increase. Higher limit + same balance = lower utilization = higher score. Call your card issuer annually.
- 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.
