Credit scores boil down to a simple three-digit number that lenders use to gauge your trustworthiness with money, typically ranging from 300 to 850. Higher scores unlock better rates on loans, credit cards, and even rentals, while low ones slam doors shut with high interest or denials.
Breaking Down the FICO Score Components
FICO remains the gold standard, powering 90% of lending decisions, calculated from five key factors weighted by impact. Each pulls from your credit reports at Equifax, Experian, and TransUnion, updated monthly.
Payment History (35%)
Paying bills on time tops everything—lenders want proof you honor commitments. Late payments over 30 days ding scores hardest, lingering seven years, though impact fades over time.
Even one missed student loan or utility bill hurts, as positive history builds steadily. Set calendar alerts and autopay to protect this pillar.
Amounts Owed (30%)
This measures credit utilization—how much of your available credit you use. Keep it under 30%, ideally 10%, across all cards; maxed-out lines signal risk.
Total debt matters less than ratios: $2,000 on a $10,000 limit beats $5,000 on $20,000. Pay down balances before statements close for optimal reporting.
Length of Credit History (15%)
Older accounts boost scores, showing long-term reliability. Average age across all cards and loans counts, plus your oldest account’s vintage.
Avoid closing ancient cards—they extend history. Teens start with authorized user status on parents’ cards for early seasoning.
New Credit (10%)
Recent applications trigger hard inquiries, viewed as potential debt hunger. Multiple pulls in weeks (like car shopping) count as one, but frequent checks over months lower scores temporarily.
Space applications six months apart. Rate shopping for mortgages or autos gets grace periods.
Credit Mix (10%)
A blend of revolving (cards) and installment (loans, mortgages) debt shows versatility. No need for everything—two cards and a car loan suffice for most.
Don’t open accounts just for mix; natural use proves management better.
VantageScore: A Modern Alternative
VantageScore 4.0, used by 2,500+ lenders, tweaks weights slightly but follows similar logic. It emphasizes total utilization and experience, scoring from 300-850 too.
Both ignore income, race, or marital status—purely credit behavior data.
