What Is a Credit Score?
A credit score is a 3-digit number (typically 300–850) that summarizes your creditworthiness — how likely you are to repay debt. Lenders use it to decide whether to approve loans and at what interest rate.
A 50-point credit score difference can mean the difference between:
Getting approved or rejected for a mortgage
Paying 6.5% vs. 7.5% on a home loan (which costs $97,000+ more over 30 years)
Paying $1,200 vs. $1,800/year for auto insurance
Your credit score is one of the most financially important numbers in your life.
The goal: Get to 740+ for access to the best mortgage rates. 760+ unlocks the absolute best tier at most lenders.
What Makes Up Your Credit Score
FICO scores are calculated from 5 factors:
Factor
Weight
What It Measures
Payment History

On-time vs. late payments
Amounts Owed

Credit utilization ratio
Length of Credit History

Recent applications and new accounts
Credit Mix

Variety of credit types
Factor 1: Payment History (35%)
The most important factor. A single 30-day late payment can drop your score 60-100 points. Bankruptcies stay for 7-10 years.
What helps: Every on-time payment. Set up autopay for at least the minimum on all accounts.
What hurts: Late payments, collections, charge-offs, bankruptcies.
Factor 2: Credit Utilization (30%)
Your utilization ratio = (Total credit card balances) ÷ (Total credit card limits).

Key insight: You can dramatically improve your score in 30-60 days simply by paying down credit card balances.
Factor 3: Credit History Length (15%)
Older accounts help your score. This is why you should generally not close old credit cards — even ones you don't use. The average age of your accounts matters.
Factors 4 & 5: New Credit & Credit Mix
Hard inquiries (from credit applications) stay on your report for 2 years and temporarily drop your score 5-10 points. Multiple mortgage/auto loan inquiries within 14-45 days count as one inquiry.
Having both revolving credit (cards) and installment loans (mortgage, auto) positively impacts your credit mix.
8 Proven Strategies to Improve Your Score
Pay every bill on time — set up autopay for minimums
Reduce credit card balances to below 30% utilization (below 10% is better)
Don't close old accounts — keep unused cards open for history and utilization benefits
Request credit limit increases — increases your available credit, reducing utilization
Dispute errors on your credit report — 1 in 5 people have errors; dispute them at AnnualCreditReport.com
Become an authorized user on a family member's old account with good history
Avoid opening multiple new accounts quickly — stagger applications
Get a secured credit card if building from scratch — use it for small purchases and pay in full monthly
