Income Statement
A financial statement showing a company's revenue, expenses, and profit (or loss) over a period.
An income statement, also called a profit and loss statement (P&L), shows a company's revenue, expenses, and profit (or loss) over a specific period, usually a quarter or year. It answers the question: "Did the company make or lose money?"
Example
Apple's (AAPL) annual income statement might show: Revenue $400 billion, Operating Expenses $250 billion, Operating Income $150 billion, Interest Expense $1 billion, Income Tax $25 billion, Net Income $124 billion. This shows how much profit was generated.
Tesla's (TSLA) income statement shows large revenue growth, but relatively tight operating margins. If revenue jumps from $80 billion to $100 billion but operating expenses also jump proportionally, net income growth lags revenue growth—margin compression.
How to Interpret It
- Revenue (top-line): Total sales before any expenses. Growing revenue is good, but growing expenses faster is bad.
- Cost of goods sold (COGS): Direct costs to make products. Lower COGS relative to revenue = better gross margin.
- Gross profit: Revenue minus COGS. Gross margin (gross profit ÷ revenue) shows production efficiency.
- Operating expenses: Sales, marketing, R&D, administrative costs. High operating expenses reduce operating income.
- Operating income (EBIT): Revenue minus all operating expenses. Shows profit from core business.
- Interest expense: Cost of debt. High interest suggests high debt levels.
- Income tax: Usually 15–25% of pre-tax income.
- Net income (bottom-line): Final profit after all expenses and taxes. This is what shareholders own.
Limitations
- Income statement uses accrual accounting, not cash accounting. Revenue is recognized when earned, not when cash is received. Expenses are recognized when incurred, not when paid.
- One-time charges or gains distort earnings in a single quarter.
- Accounting choices (depreciation method, revenue recognition timing) affect reported profit.
- Doesn't show cash flow—a profitable company can run out of cash.
- Doesn't account for non-cash items like stock-based compensation until expenses are recorded.
- Income statement covers a past period and doesn't predict future earnings.

Frequently Asked Questions
Why is it called an income statement AND a P&L statement?
Income statement and P&L (profit and loss) statement are the same thing—two names for the same document. Companies might also call it an 'earnings statement' or 'statement of operations.'
What's the difference between top-line and bottom-line?
Top-line is revenue (at the top of the income statement). Bottom-line is net income/profit (at the bottom). Growing top-line is good; if bottom-line shrinks while top-line grows, margins are being squeezed.
Why does profit differ from cash flow?
Income statements use accrual accounting (revenue when earned, even if not paid; expenses when incurred). Cash flow shows actual cash movement. A company can be profitable but run out of cash, or unprofitable but have positive cash flow.
