Credit Scores

A credit score is a three-digit number that serves as your financial report card, summarizing your history of managing debt. Lenders, from credit card companies to mortgage providers, use this score to quickly assess your creditworthiness—essentially, the risk they're taking by lending you money. A higher score signals to lenders that you are a reliable borrower who is likely to repay your debts on time, making you eligible for better loan terms and lower interest rates. In the United States, the most widely recognized score is the FICO score, created by the Fair Isaac Corporation, and it's calculated using data from three major credit bureaus: Equifax, Experian, and TransUnion. While scoring models and bureaus can differ slightly, particularly between the US and Europe, the underlying principle is universal: they provide a snapshot of your financial reliability based on your past behavior.

Think of your credit score as a recipe with a few key ingredients. While the exact formula is a trade secret, the creators of the FICO score have shared the main components and their approximate weighting. Understanding these ingredients empowers you to improve your financial health.

• Payment History (approx. 35%): This is the single most important factor. A consistent record of paying your bills on time, every time, is the foundation of a great score. Late payments, bankruptcies, and collections can cause significant damage.
• Amounts Owed (approx. 30%): This looks at how much debt you carry, particularly your credit utilization ratio—the amount of revolving credit you're using compared to your total credit limit. A ratio below 30% is good, but under 10% is even better. Maxing out your credit cards is a major red flag.
• Length of Credit History (approx. 15%): A longer track record of responsible borrowing is a positive sign. This is why it's often wise to keep your oldest credit accounts open, even if you don't use them frequently.
• Credit Mix (approx. 10%): Lenders like to see that you can responsibly manage different types of credit, such as a mix of credit cards (revolving credit) and installment loans (like a car loan or mortgage).
• New Credit (approx. 10%): This factor considers how many new credit accounts you've recently opened or applied for. Opening several new accounts in a short period can suggest you're in financial trouble and can temporarily lower your score.

For a value investor, the concept of a credit score is more than just personal finance—it’s a powerful lens through which to view both personal opportunities and corporate health.

A strong personal credit score is a superpower for an investor. It directly lowers your personal cost of capital. When you can borrow money at a lower interest rate, your investment returns are amplified. Consider financing a rental property; a lower mortgage rate could be the difference between a profitable venture and a break-even headache. A high score reflects financial discipline—a trait that is non-negotiable for long-term investing success. It shows that you manage your own balance sheet effectively before you even start analyzing a company's.

Just as individuals have credit scores, companies have credit ratings issued by agencies like Moody's and Standard & Poor's (S&P). This rating is, in effect, the company's “credit score.” A value investor, who meticulously analyzes a company's financial stability, should treat this rating as a critical piece of the puzzle.

• A Sign of Health: A company with a high credit rating (e.g., AAA or AA) is seen as financially robust and at low risk of default. This means it can borrow money cheaply, leaving more profit for innovation, growth, and ultimately, for its shareholders. Warren Buffett famously favors businesses that are not heavily reliant on debt.
• A Warning Signal: A low or declining credit rating is a serious warning. It signals that the company must pay more for its debt, which erodes profits. It may also indicate poor management or a deteriorating position in the market. While a low rating can sometimes create a buying opportunity if the market overreacts, it always demands deeper investigation into the company's balance sheet and debt structure.

Your personal credit score is not just a number; it’s a direct reflection of your financial habits and a critical tool for building wealth. By keeping it high, you lower your borrowing costs and demonstrate the discipline required for successful investing. When you put on your investor hat, look for the corporate equivalent: the credit rating. It provides a quick, powerful insight into a company's financial stability and management quality. For a value investor, a company that manages its debt as prudently as you manage your own is often a business worth a closer look.
