Credit allows consumers to purchase goods and services now and pay for them later. When using credit, finance charges in the form of interest and fees are usually incurred. The amount of credit used, annual percentage rate, and length of repayment time all affect the size of finance charges. While credit provides advantages like convenience and access to costly items, it also poses disadvantages like reducing future income and risk of serious consequences if misused. Different types of credit include sales credit for purchases and cash credit for loans. Establishing a good credit history involves steps like maintaining employment, managing bank accounts responsibly, and initially using small credit limits and paying bills on time.
