Revenue, also known as sales or turnover, is a financial term that refers to the total amount of money earned by a company through its normal business operations during a specific period of time. Revenue is typically calculated by multiplying the number of units sold by the price per unit. This can include revenue from the sale of goods or services, as well as any other sources of income such as interest or rental income. Revenue is an important metric for evaluating a company's financial health and growth potential. There are different types of revenue, such as gross revenue, net revenue, and recurring revenue. Gross revenue represents the total amount of money earned by the company before any deductions or expenses are subtracted. Net revenue represents the amount of revenue earned after all deductions and expenses have been subtracted, such as cost of goods sold, operating expenses, and taxes. Recurring revenue is revenue that is earned on an ongoing basis, such as subscription fees or maintenance contracts. Revenue is a key performance indicator for businesses and is often used by investors, analysts, and other stakeholders to evaluate a company's financial performance and growth potential. However, it should be used in conjunction with other financial metrics such as net income, profit margin, and cash flow to gain a more comprehensive understanding of a company's financial health and future prospects.
