What the Income Statement Is and How It Works: Understanding the Structure of the Income Statement

The Income Statement, or the Profit and Loss Statement (P&L), is one of the main financial statements utilized by companies to evaluate their performance during a given period. It gives an overview of a firm's revenues, expenses, and profits or losses. The statement is crucial for investors, managers, creditors, and analysts to know how well a company is performing.
What Is the Income Statement?
The Income Statement indicates how much revenue a business generated during an interval (e.g., a quarter or a year), and the expenses and costs of generating that revenue. The net income, the bottom of the income statement, is the profit or loss of the company after all revenues and expenses have been included.
In simple terms:
Revenue – Expenses = Net Income
