Your credit score controls your mortgage rate, car loan rate, apartment applications, and sometimes job offers. Here's how it actually works.
FICO Score breakdown (Source: myFICO.com):
- Payment history: 35% — On-time payments. One 30-day late payment can drop your score 60-110 points.
- Credit utilization: 30% — How much of your available credit you're using. Keep it under 30%. Under 10% is ideal.
- Length of credit history: 15% — Average age of accounts. This is why you should never close your oldest card.
- Credit mix: 10% — Variety of credit types (cards, installment loans, mortgage).
- New credit inquiries: 10% — Hard pulls from applications. Each one knocks 5-10 points.
Common myths debunked:
-
"Checking your own score hurts it." FALSE. Checking your own score is a soft pull. Zero impact. Source: CFPB.
-
"Carrying a balance helps your score." FALSE. Pay your statement balance in full every month. Utilization is calculated on statement balance, not carried balance.
-
"Closing old accounts helps." FALSE. It shortens your average account age and reduces total available credit (increasing utilization ratio).
-
"Income affects your score." FALSE. Income is not a FICO factor.
-
"All credit checks are equal." FALSE. Rate shopping for a mortgage or car loan within 14-45 days counts as ONE inquiry. Source: FICO.
