什么是 Income Statement (P&L)？
定义
An income statement (also called a profit and loss statement or P&L) shows a company's revenues, expenses, and net profit or loss over a specific period. It is the primary tool for assessing business profitability and one of the three core financial statements.
The income statement flows from top-line revenue to bottom-line net income: Revenue minus Cost of Goods Sold (COGS) equals Gross Profit. Gross Profit minus Operating Expenses (sales, marketing, G&A, R&D) equals Operating Income (EBIT). Operating Income minus Interest Expense equals Pre-Tax Income. Pre-Tax Income minus Income Tax equals Net Income. Key profitability ratios derived from the income statement include Gross Margin (Gross Profit ÷ Revenue), Operating Margin, and Net Margin. Under accrual accounting, revenue and expenses are recorded when earned or incurred — not when cash changes hands — so net income can differ significantly from cash flow. The income statement covers a period (month, quarter, year), distinguishing it from the balance sheet (a point-in-time snapshot) and the cash flow statement (which reconciles income to actual cash movement).
为什么重要
A clean, accurate P&L is fundamental to understanding profitability, where costs are growing faster than revenue, and how your margins compare to industry benchmarks. Lenders, investors, and acquirers scrutinize income statements in due diligence. An accountant ensures your P&L accurately reflects your business; a financial advisor helps you interpret what it means strategically.
