An income statement is a financial statement that shows a company's revenues, other income, and expenses over a specific period of time, usually a quarter or a year. The purpose of the income statement is to provide investors, creditors, and other stakeholders with information about a company's financial performance.

Revenue: Revenue is the money a company earns from the sale of goods or services. It is the top line of the income statement and is often referred to as sales or turnover. Revenue is calculated by multiplying the number of units sold by the price per unit.

Other Income: Other income is income that a company earns from sources other than its primary business activities. This can include interest income, rental income, and gains from the sale of assets. Other income is typically reported separately from revenue on the income statement.

Expenses: Expenses are the costs a company incurs in order to generate revenue. They include the cost of goods sold, operating expenses, and interest and taxes. The difference between revenue and expenses is the company's net income or profit.

The income statement is a key financial statement that provides important information about a company's financial performance. It is used by investors, creditors, and other stakeholders to evaluate the company's profitability and financial health.
