Having good credit is essential for financial health in the U.S., influencing your ability to rent an apartment, get a loan, or even qualify for a job. Establishing and maintaining strong credit requires consistent financial discipline and an understanding of how the credit system works.

The most commonly used credit score in the U.S. is the FICO score, which ranges from 300 to 850. It's calculated using five key factors: payment history (35%), credit utilization (30%), length of credit history (15%), credit mix (10%), and new credit inquiries (10%). Knowing how these elements affect your score is the first step to building strong credit.

If you’re just starting, a secured credit card or being added as an authorized user on a family member’s account can be smart entry points. A secured card requires a deposit but functions like a regular credit card. Make small purchases and pay them off in full each month to demonstrate responsible use.

Whether it’s your phone bill, credit card, or loan, timely payments are essential. Set calendar reminders or enable auto-pay to avoid late fees. Consistent on-time payments show lenders that you're reliable, which significantly boosts your credit score.

Credit utilization refers to how much of your available credit you’re using. Ideally, keep it below 30%, and even better if it’s under 10%. For instance, if you have a $2,000 limit, try to carry no more than $200–$600 in balance at any given time. Paying off your balance before the statement closes also helps.

Every time you apply for credit, a hard inquiry is added to your report, which can lower your score temporarily. Avoid applying for multiple cards or loans in a short time unless absolutely necessary. Soft inquiries, like checking your own score, don’t impact your credit.

Having both revolving credit (like credit cards) and installment credit (like car or student loans) shows you can manage various types of debt responsibly. However, never take on debt just to diversify—only borrow what you can repay.
