What Is a Good Credit Score — and How to Improve Yours in 6 Months

In the United States, 65% of adults have a credit score of 700 or higher, according to Experian. However, many Americans still struggle with understanding what a "good" credit score means and how to achieve one. A strong credit score can save you thousands of dollars in interest over your lifetime. For example, someone with a 650 credit score might pay 3.5% more in interest on a $30,000 car loan compared to someone with a 750 score. This difference adds up to over $4,000 in additional interest over a 5-year loan term. Understanding how credit scores work and taking steps to improve them is critical for long-term financial stability.

What Is a Good Credit Score?

Credit scores in the U.S. are typically calculated using the FICO model, which ranges from 300 to 850. A "good" credit score is generally considered to be 670 or higher, while "excellent" scores start at 800. These scores are determined by five key factors: payment history (35%), amounts owed (30%), length of credit history (15%), new credit (10%), and credit mix (10%). Lenders use these scores to assess creditworthiness, and a higher score often means better loan terms, lower interest rates, and more borrowing options. For example, with 30-year fixed mortgage rates in the 6.5–7% range (2024 averages), a borrower with a 700 score may qualify near the lower end of lender offers, while someone with a 650 score is often quoted a rate 0.5–1.0 percentage points higher. Over a 30-year loan, that gap can result in tens of thousands of dollars in additional interest payments. Understanding where you stand on the credit score spectrum is the first step toward improving your financial health.

The Cost of a Poor Credit Score

A low credit score can have far-reaching financial consequences. Consumers with poor credit scores (below 620) typically pay significantly higher interest rates on credit cards, auto loans, and mortgages. The Federal Reserve reports that average credit card APRs reached approximately 21–22% in 2023–2024, and borrowers with weaker credit profiles are often quoted rates well above that average. Over a year, even a few extra percentage points on a $5,000 balance can add hundreds of dollars in interest charges. Additionally, landlords and insurance companies often use credit scores to determine rent deposits, security deposits, and insurance premiums. A low credit score might result in a $500 security deposit for an apartment, while someone with a good score might not need to pay anything. These hidden costs add up, making it even more important to prioritize improving your credit score.

How Credit Scores Are Calculated

Your credit score is based on data from your credit reports, which are maintained by the three major credit bureaus: Experian, TransUnion, and Equifax. Payment history is the most significant factor, accounting for 35% of your score. Late payments, collections, and bankruptcies can drag down your score. For example, a single 30-day late payment on a credit card can reduce your score by 60–110 points depending on your starting score and overall credit profile — the higher your score going in, the more dramatic the drop. The second most important factor is amounts owed, which makes up 30% of your score. This includes your credit utilization ratio—the percentage of your available credit that you're using. A utilization rate above 30% can negatively impact your score. For instance, if you have a $10,000 credit limit and a $4,000 balance, your utilization rate is 40%, which is considered high and could lower your score.

Steps to Improve Your Credit Score in 6 Months

Improving your credit score doesn't require overnight changes. With consistent effort, you can boost your score by 50-100 points in six months. Start by paying all bills on time, including credit cards, rent, and utilities. Even one late payment can hurt your score, so consider setting up automatic payments or calendar reminders. Next, work on reducing your credit card balances. Aim to keep your utilization rate below 30%. If you have high balances, consider transferring debt to a lower-interest credit card or negotiating a payment plan with your creditors. Additionally, avoid opening new credit accounts unless absolutely necessary, as new credit inquiries can temporarily lower your score.
