Revenue is the total money realized from sales of goods or services. It is the income a company or organization generates from its business activities before deducting any expenses or costs. Revenue is a key financial metric that is used to measure the financial performance of a business. It is calculated by multiplying the price of each unit sold by the total number of units sold. For example, if a company sells 100 units of a product at $10 per unit, its revenue would be $1,000. Revenue is an important factor in determining a company's profitability and financial health.
