Which financial statement details information about revenues, expenses, and profit over a period of time?

The Income Statement is the financial statement that provides a comprehensive overview of a company's financial performance over a specific period. It summarizes the revenues generated and the expenses incurred, ultimately leading to the calculation of net profit or loss for that timeframe. This statement is crucial for understanding how well a company is performing in terms of generating income relative to its costs.

In contrast, the Balance Sheet focuses on a company's assets, liabilities, and equity at a particular point in time, providing a snapshot of financial health rather than performance over a period. The Statement of Cash Flows details the cash inflows and outflows from operating, investing, and financing activities but does not directly address profit or loss. The Equity Statement, often part of broader financial reporting, outlines changes in owners' equity over time, but again does not provide a direct analysis of revenues and expenses as the Income Statement does. Thus, the Income Statement is the key document for assessing a business's financial performance over time.
