What Is a Credit Score? Your Financial Reputation

A credit score is a three-digit number (typically 300-850) that represents your creditworthiness — how likely you are to repay borrowed money. Lenders use it to determine whether to extend credit, at what interest rate, and on what terms. A higher score means better rates and lower costs on every form of borrowing — mortgages, car loans, credit cards, and personal loans. Your credit score is, in effect, the price tag on your financial reputation.

What Determines Your Score

The FICO score — used by 90% of lenders — weighs five factors. Payment history (35%): whether you've paid past obligations on time. This is the most important factor — a single missed payment can drop your score 50-100 points. Amounts owed (30%): how much of your available credit you're using (credit utilization). Lower utilization is better — keeping balances below 30% of limits is the standard advice, below 10% is optimal.

Length of credit history (15%): how long your accounts have been open. Longer history is better. Credit mix (10%): having different types of credit (credit cards, installment loans, mortgage) is viewed positively. New credit (10%): multiple recent applications or new accounts lower your score temporarily.

Score Ranges and What They Mean

800-850 (Exceptional): the best rates available on every product. 740-799 (Very Good): qualifying for most premium rates. 670-739 (Good): generally qualifying for credit but not at the best rates. 580-669 (Fair): subprime territory — higher rates and limited options. Below 580 (Poor): difficulty qualifying for most credit products.

Why Credit Scores Matter for Investors

Good credit frees up capital for investing. A strong credit score means lower mortgage rates (saving tens of thousands over a 30-year loan), lower car loan rates, and lower insurance premiums. Every dollar saved on interest is a dollar available for investment. Over a lifetime, the difference between excellent and poor credit can exceed $100,000 in interest costs alone — money that could have been compounding in your investment portfolio.

Access to cheap credit also provides strategic flexibility. Investors with excellent credit can access home equity lines of credit (HELOCs) or margin at favorable rates for short-term liquidity needs — without selling investments at inopportune times. Good credit is financial optionality.

Building and Maintaining Good Credit

Pay every bill on time — set up autopay for at least the minimum on every account. Keep credit utilization low — pay balances in full monthly if possible. Don't close old accounts — length of history matters. Limit new applications — each inquiry temporarily reduces your score.

Good credit is a financial foundation — like an emergency fund, it's something you build before you need it. Establishing excellent credit in your twenties and thirties creates the financial infrastructure that supports decades of wealth building through lower borrowing costs and greater financial flexibility. One thing that catches people off guard: closing old credit accounts can actually hurt your score by reducing your credit history length and increasing your utilization ratio.
