A credit score is a number that lenders use to judge how likely you are to repay borrowed money. A higher score can help you qualify for loans and credit cards and often lets you borrow at a lower interest rate. Over the life of a mortgage or car loan, a better rate can save thousands of dollars. This guide explains how scores work and what you can do to improve yours.

What Is a Credit Score?

In the United States, the most common scores range from 300 to 850. Higher is better. Lenders often group scores into broad ranges such as poor, fair, good, very good, and excellent, but each lender sets its own rules. Your score is calculated from the information in your credit reports, which record your borrowing and repayment history.

What Affects Your Score?

Scoring models differ, but the widely used FICO model describes these main factors and their approximate weight:

These weights are general and can vary from person to person.

Step 1: Pay Every Bill on Time

Payment history is the biggest factor, so this is the most important habit. Even one payment that is 30 days or more late can lower your score and may stay on your report for years. Set up automatic payments for at least the minimum amount, or add calendar reminders for due dates.

Step 2: Keep Your Credit Card Balances Low

Credit utilization is the share of your credit limit that you are using. For example, if your limit is $5,000 and your balance is $1,500, your utilization is 30%. Many experts suggest keeping it below 30%, and lower is generally better. Paying down balances, or paying before the statement closes, can help reduce the number that gets reported.

Step 3: Check Your Credit Reports for Errors

Mistakes on a credit report, such as an account that is not yours or a payment wrongly marked late, can hurt your score. In the United States you can request free reports from the three major credit bureaus through the official site, AnnualCreditReport.com. If you find an error, you can dispute it with the bureau, and the bureau must investigate.

Step 4: Do Not Close Old Accounts Without Thinking

Older accounts add to the average age of your credit history. Closing your oldest card can shorten that history and also reduce your total available credit, which can raise your utilization. If a card has no annual fee, keeping it open and using it occasionally for a small purchase that you pay off may be helpful.

Step 5: Apply for New Credit Carefully

Each time you apply for a loan or card, the lender usually does a hard inquiry, which can lower your score slightly for a time. Several applications in a short period can add up. Apply only when you need the credit and compare offers carefully before you apply.

Step 6: Build a Mix Over Time

Having both revolving credit, like credit cards, and installment loans, like a car loan, can help a little. However, you should never take on debt only to improve your score. Mix is a small factor, and it is less important than paying on time and keeping balances low.

Step 7: Be Patient and Consistent

Credit scores do not change overnight. Positive habits build up over months and years. Late payments and many other negative items typically stay on your report for up to seven years, though their effect lessens as time passes. Steady, on-time payments are the most reliable path upward.

If You Have Little or No Credit History

If you are just starting, options may include a secured credit card, where you put down a refundable deposit, or becoming an authorized user on a trusted person's account. Use the card for small purchases and pay the balance in full each month. Always read the fees and terms first.

Connect Your Score to Your Money Plans

A better score can lower the interest you pay, which makes debt cheaper to clear. See how credit card interest works and compare payoff plans in our guide to debt snowball vs debt avalanche. You can also estimate how a lower rate changes your payment with our Loan Calculator.
