Building credit involves establishing a positive credit history and maintaining responsible credit habits to demonstrate creditworthiness to lenders. This is typically done by using credit products like credit cards or loans responsibly, making timely payments, and keeping balances low relative to credit limits. A good credit history and high credit score can lead to better loan terms, lower interest rates, and increased access to financial opportunities such as mortgages or car loans. It’s a gradual process that requires consistent financial behavior and responsible debt management.
