What is an Income Statement?

An income statement — also called a profit and loss statement (P&L) — is one of the three core financial statements every business produces. It shows how much money a company earned, how much it spent, and whether it made a profit or loss over a specific time period (a month, quarter, or year).

What Does an Income Statement Show?

The income statement starts at the top with revenue — all the money coming in from sales. Then it subtracts the costs of producing those sales (Cost of Goods Sold, or COGS) to arrive at gross profit. Next, operating expenses like salaries, rent, and marketing are subtracted to get operating income. Finally, taxes and interest leave you with net income — the company's bottom line.

Why the Income Statement Matters for Your Team

In open book management, the income statement is the scoreboard. When employees understand how their daily decisions affect revenue and expenses, they stop thinking like bystanders and start thinking like owners. A customer service rep who understands gross margin will handle returns differently. A production worker who sees labor costs in context will flag inefficiencies.

Income Statement vs. Other Financial Statements

The income statement covers a period of time (unlike the balance sheet, which is a snapshot). Its net income figure flows directly into the balance sheet via retained earnings and into the cash flow statement as the starting point for operating activities. Understanding how these three statements connect is the foundation of financial literacy.
