Your credit score summarizes how reliably you use borrowed money. Five factors drive most models:
1) Payment history (~35%): Pay on time, every time. Automate minimums. 2) Utilization (~30%): Keep used credit below 30% of your limits; under 10% is ideal. 3) Length of history (~15%): Older accounts help—avoid closing your oldest card. 4) Mix (~10%): A variety (card + installment) can help, but don’t borrow just for variety. 5) New credit (~10%): Too many recent applications can lower your score temporarily.
Protect your score • Enable account alerts and two-factor authentication. • Dispute errors with your credit bureau. • If a card is compromised, request a new number and monitor statements.
