People can spend money using cash, credit cards, or debit cards. Cash involves coins and banknotes, credit cards allow borrowing from banks with interest, and debit cards directly withdraw from bank accounts. People also save money through saving accounts that earn interest, money boxes, shares in businesses, and bonds that provide interest from governments or companies. Money can be spent on consumer products that are high-order and infrequently purchased like cars or low-order essentials like food, as well as services like utilities, restaurants, and entertainment. People develop budgets to plan spending on necessities and costs for households or businesses.
