The income statement is a financial report that summarizes a company’s revenues, expenses, and net profit over a specific period. It helps assess a company’s profitability and operational efficiency. In essence, a company’s income statement must equal the formula Net Income=Revenue−Expenses.
The following example shows the trickle-down equation from revenue to net income:

The bottom line (i.e., net income) of the income statement flows into the balance sheet under shareholders’ equity.
Revenue = Sales
Revenue is total income generated from all business activities, including sales.
