What Is Net Income?
Net income is the profit a company keeps after subtracting every cost: cost of goods sold, operating expenses, interest payments, and taxes. It's the number at the very bottom of the income statement — which is why investors call it "the bottom line."
Think of it as what's left in the company's pocket at the end of the year. Revenue is what flows in the door. Net income is what stays.
Net income answers one fundamental question: Is this company actually making money — after paying for everything it takes to run the business?
TL;DR: Net income is a company's total profit after all costs and taxes. A positive and growing net income signals a profitable, financially sustainable business. Use the Net Income filter on ScreenerHub to screen only for companies that are consistently earning — not just generating revenue.
Why Net Income Matters for Investors
Revenue tells you how big a business is. Net income tells you whether it's a good business.
A company can generate billions in revenue and still be losing money — if its costs are even higher. Net income cuts through the noise and shows you the actual result.
Here's why net income belongs in every fundamental screen:
- Profitability confirmation. A company with positive net income is self-sustaining. One with negative net income is burning through cash — which is fine for early-stage growth companies but a red flag for mature businesses.
- Earnings per share foundation. EPS is net income divided by the number of shares outstanding. If you care about EPS — and most investors do — you're already relying on net income.
- Dividend sustainability. Companies pay dividends from net income (or retained earnings). A business paying out more in dividends than it earns in net income is living on borrowed time.
- Valuation anchor. The P/E ratio, one of the most widely used valuation metrics, is built on EPS, which is built on net income. Understanding net income helps you understand what you're actually paying for.
How Net Income Is Calculated
Net income is the end of the income statement waterfall. Every line above it represents a cost being subtracted from revenue.
Worked example — a hypothetical retailer:
| Income Statement Line | Amount |
|---|---|
| Revenue | $500M |
| Cost of Goods Sold (COGS) | − $300M |
| Gross Profit | $200M |
| Operating Expenses (SG&A) | − $80M |
| Operating Income (EBIT) | $120M |
| Interest Expense | − $15M |
| Pre-Tax Income (EBT) | $105M |
| Income Tax (21%) | − $22M |
| Net Income | $83M |
This company turns $500M in revenue into $83M in net income — a net profit margin of 16.6%.
Note: Most screeners, including ScreenerHub, display both raw net income (in millions/billions) and net profit margin (as a percentage). The margin is usually more useful for comparing companies of different sizes.
Net Income vs. Related Metrics
Net income is powerful, but it sits in a family of profitability metrics — each measuring a different slice of the business:
| Metric | What It Measures | Best For |
|---|---|---|
| Revenue | Total sales before any costs | Company size, growth rate |
| Gross Profit | Revenue minus COGS only | Production efficiency, pricing power |
| Operating Income | Profit before interest and taxes | Core business performance, ignores financing |
| Net Income | Profit after all costs, interest, and tax | Final profitability; basis for EPS |
| Free Cash Flow | Cash generated after capital expenditures | Cash generation quality; harder to manipulate |
The key difference between net income and revenue: Revenue growing while net income shrinks means costs are rising faster than sales — a warning sign. Revenue and net income both growing at a similar pace? That's the pattern you want.
What Is a Good Net Income Margin?
Net income in absolute terms ($500M) tells you little without knowing the company's size or industry. Net profit margin — net income as a percentage of revenue — is the better comparison tool.
Interpretation guide
| Net Profit Margin | What It Suggests |
|---|---|
| Below 0% | Unprofitable. Negative EPS, no P/E ratio. Requires other valuation metrics. |
| 0% – 5% | Thin margins. Common in retail, logistics, and commodity businesses. |
| 5% – 15% | Moderate margins. Typical for industrials, healthcare, consumer staples. |
| 15% – 25% | Strong margins. Well-run businesses with pricing power or scalable models. |
| Above 25% | High margins. Common in software, pharmaceuticals, and asset-light platforms. |
Sector benchmarks (approximate U.S. market averages)
Net profit margins vary widely by sector. Never compare margins across industries without context.
| Sector | Typical Net Margin | Why |
|---|---|---|
| Software / SaaS | 15% – 30%+ | Low marginal costs once the product is built |
| Pharmaceuticals | 15% – 25% | High pricing power on patented drugs |
| Consumer Staples | 5% – 12% | High volume, competitive pricing, thin margins |
| Retail | 2% – 6% | Volume-driven, high COGS and operating costs |
| Energy | 3% – 12% | Volatile, commodity-dependent earnings |
| Financials (Banks) | 15% – 25% | Interest income model; less comparable to others |
| Industrials | 5% – 12% | Capital-intensive, cyclical |
| Healthcare Services | 3% – 10% | High operating costs, reimbursement pressure |
Always compare a company's net margin to its sector peers — not to the market average. A 5% margin in retail is solid. A 5% margin in software is a concern.

How to Use Net Income in Stock Screening
Net income becomes a powerful screening tool when you combine it with other filters. Here are three practical screens:
Screener 1: Profitable quality stocks
Screen for consistently profitable companies with strong fundamentals.
| Filter | Setting |
|---|---|
| Net profit margin | > 10% |
| Revenue growth (1Y) | > 5% |
| Market cap | > $1B |
| Debt-to-equity | < 1.0 |
This screen filters out companies burning cash, focuses on mid-to-large businesses with growing revenues, and ensures profits aren't built on an unsustainable debt pile. A solid starting point for most long-term investors.
Screener 2: Profitable growth at scale
Find larger companies that are profitable and growing their earnings meaningfully.
| Filter | Setting |
|---|---|
| Market cap | > $5B |
| Net profit margin | > 15% |
| Revenue growth (1Y) | > 10% |
| Earnings growth (1Y) | > 10% |
When revenue growth and earnings growth both exceed 10%, it means the company is not only scaling sales — it's also improving profitability. This combination is rarer and more valuable than revenue growth alone.
<!-- [SCREENSHOT: ScreenerHub Studio — large-cap screen with Net Profit Margin > 15% and Revenue Growth > 10%, showing matching results] -->
Screener 3: Dividend sustainability check
Ensure a dividend-paying company is actually earning enough to sustain its payout.
| Filter | Setting |
|---|---|
| Dividend yield | > 2% |
| Net profit margin | > 8% |
| Payout ratio | < 60% |
| Debt-to-equity | < 1.0 |
A company with a healthy dividend yield and a net margin above 8% is far less likely to cut its dividend than one paying out more than it earns. The payout ratio filter adds a second layer: it confirms dividends are well-covered by earnings.
Try it now: Open the Screener Studio and add a Net Profit Margin filter. Set it above 10%, then pair it with a Revenue Growth filter to find businesses that are profitable and growing. Results update instantly.
When Net Income Misleads
Net income is essential — but it has real limitations. Knowing them makes you a sharper analyst:
1. One-time items distort the picture
Net income can be inflated by asset sales, tax benefits, or insurance payouts — none of which are repeatable. Likewise, a one-time write-down can crater net income in a year when the underlying business is healthy.
Mitigation: Look at net income trends over 3–5 years, not just a single year. Check whether earnings quality is consistent.
2. Accounting choices affect the number
Depreciation methods, revenue recognition timing, and treatment of stock-based compensation all give companies flexibility in how they report net income.
Mitigation: Pair net income with free cash flow. When the two diverge significantly, investigate why.
3. Debt-financed profits can mislead
A company can boost net income by cutting interest costs through low-rate debt — a structure that works until rates rise or refinancing becomes costly.
Mitigation: Add a Debt-to-Equity filter to any net income screen. High earnings built on high leverage deserve extra scrutiny.
4. Negative net income isn't always fatal
Early-stage growth companies may have negative net income for years while building market share. Amazon ran near break-even for a decade. For these companies, use revenue growth and gross margin instead.
Frequently Asked Questions
Is net income the same as profit?
Yes, in most contexts. "Net income," "net profit," and "the bottom line" all refer to the same figure: what remains after all expenses have been deducted from revenue.
What's the difference between net income and gross profit?
Gross profit only subtracts the direct cost of goods sold from revenue — it ignores operating expenses, interest, and taxes. Net income subtracts everything. Gross profit shows how efficient the production process is; net income shows the overall business outcome.
Can a company have positive revenue and negative net income?
Yes, and this is common. A company generating $1B in revenue but spending $1.1B in total costs has negative net income (-$100M) despite strong sales. Revenue growth without net income improvement is a yellow flag, not a green one.
Why do some fast-growing companies have negative net income?
Growth companies deliberately invest heavily — in R&D, sales, infrastructure — which creates large expenses that exceed current revenues. They bet that today's losses build tomorrow's profits. This strategy works for some (Amazon, Spotify) and fails for others. Screen for gross margin as a proxy for underlying economics when net income is negative.
How does net income relate to EPS?
EPS (Earnings Per Share) is simply net income divided by the number of shares outstanding. A company with $100M in net income and 50M shares outstanding has EPS of $2.00. EPS lets you compare profitability across companies of different sizes on a per-share basis.
