Net income is the final profit after subtracting all expenses, interest and taxes. It is the bottom line of the income statement and represents the earnings available to shareholders.
How it relates
Where it fits
Net income, also called net profit, net earnings, or the "bottom line," represents the final profit remaining after all expenses—including cost of goods sold, operating expenses, interest, taxes, and any other charges—are subtracted from revenue. This is the ultimate measure of accounting profitability and the amount theoretically available to common shareholders.
The calculation path:
Net Income = Revenue - Cost of Goods Sold - Operating Expenses - Interest Expense - Income Tax Expense +/- Other Items
Why net income matters:
- Shareholder returns: Source of dividends and retained earnings for growth
- EPS calculation: Net Income / Shares Outstanding = Earnings Per Share
- Valuation basis: P/E ratios and earnings-based valuations use net income
- Performance summary: Captures all activities in one number
Net profit margin:
Net Margin = Net Income / Revenue × 100
Industry benchmarks:
- Software: 15-30% net margins for mature companies
- Consumer goods: 5-15% net margins
- Retail: 2-5% net margins
- Banks: 20-30% net margins (different business model)
- Utilities: 8-15% net margins
Earnings quality assessment:
- Cash conversion: Does net income convert to operating cash flow?
- Recurring vs. one-time: Exclude unusual items for sustainable earnings
- Accounting choices: Conservative vs. aggressive recognition policies
- Accrual buildup: Growing accruals may signal future reversals
GAAP vs. Non-GAAP earnings:
- GAAP net income: Official accounting measure
- Adjusted earnings: Excludes stock compensation, restructuring, acquisition costs
- Core earnings: Management's view of sustainable profitability
Important caveats:
- Not cash: Net income includes non-cash items
- Manipulable: Accounting choices significantly affect reported income
- Backward-looking: Reflects past period, not future prospects
Track net income alongside operating cash flow. Persistent gaps between the two warrant investigation. Sustainable businesses generate net income that converts to cash over time.
