Key Takeaways
Revenue is the top line (total sales), profit can refer to any margin level, and earnings almost always means net income — the bottom line after all expenses and taxes.
The income statement waterfall — from revenue through gross profit, operating income, and net income — reveals where a company's costs sit and how efficiently it converts sales into profit. Apple's Q1 FY2026 waterfall showed a 29.3% net margin, meaning it kept $42.1 billion of its $143.8 billion in revenue.
Earnings per share (EPS) is the single most watched metric in equity investing because it normalizes profitability on a per-share basis and feeds directly into the PE ratio, which investors use to assess whether a stock is fairly valued.
No single profit metric tells the whole story — gross margin, operating margin, net margin, EBITDA, and free cash flow each answer different analytical questions, and sophisticated investors examine several together.
Always track margin trends over multiple quarters rather than fixating on a single period, and watch for red flags like revenue growth paired with shrinking net income or persistent gaps between GAAP and non-GAAP earnings.
If you have ever read a quarterly earnings report and wondered whether "earnings" and "profit" mean the same thing, you are not alone. These terms are often used interchangeably in financial media, but they carry distinct meanings depending on context. Revenue, profit, earnings, net income, EPS — the vocabulary of corporate finance can feel like a maze, and misunderstanding any one term can lead to poor investment decisions.
The good news is that the underlying logic is straightforward once you see how the numbers flow through a company's income statement. In this guide, we will walk through each term step by step, using real financial data from Apple Inc. (AAPL) — one of the most widely followed stocks in the world — to illustrate exactly how revenue becomes gross profit, then operating profit, and finally net income. By the end, you will be able to read any earnings report with confidence and know which profit metric matters most for the decision you are trying to make.
Whether you are evaluating a stock for the first time or sharpening your analytical toolkit, understanding the hierarchy of profitability metrics is foundational. Let us start with the basics and work our way up.

Conclusion
The difference between earnings and profit is less about the words themselves and more about understanding which layer of the income statement you are examining. Revenue is the top line. Gross profit, operating profit, and net income each peel away a different set of costs. Earnings, in standard usage, refers to net income — the bottom line — and earnings per share (EPS) is the single most watched metric in equity investing. EBITDA, free cash flow, and adjusted earnings each serve specific analytical purposes but should be used alongside, not instead of, standard GAAP figures.
Apple's Q1 FY2026 results illustrate this hierarchy clearly: from $143.8 billion in revenue, the company retained $42.1 billion in net income — a 29.3% net margin — and reported diluted EPS of $2.85. Those numbers, placed within the context of a 33.4x PE ratio and a $3.88 trillion market cap, give you everything you need to start forming a view on valuation. The same analytical framework applies to every public company you will ever evaluate.
Master this vocabulary and the income-statement waterfall, and you will never again be confused by an earnings headline. More importantly, you will be equipped to look past the headline and ask the right follow-up questions — which is where real investment insight begins.

Revenue (also called "sales" or "top line") is the total amount of money a company brings in from selling its products and services before any expenses are subtracted. When Apple reported $143.8 billion in revenue for Q1 FY2026, that figure represented every dollar collected from iPhone sales, services subscriptions, Mac purchases, and everything else — with nothing deducted yet.
Profit is what remains after subtracting costs from revenue. However, the word "profit" on its own is imprecise because there are several layers of profit, each subtracting a different set of costs. Gross profit subtracts only the direct cost of making products. Operating profit subtracts operating expenses on top of that. Net profit subtracts everything, including taxes and interest.
Earnings in everyday financial usage is essentially synonymous with net income — the bottom line after all expenses, taxes, and interest have been paid. When analysts say a company "beat earnings," they mean the reported net income (usually expressed as earnings per share) exceeded the consensus forecast. So while "profit" can refer to any layer of the income statement, "earnings" almost always points to the final number.
Here is a simple rule of thumb: revenue is the top line, profit can refer to any margin along the way, and earnings is the bottom line. The distinctions matter because a company can grow revenue rapidly while its earnings shrink — or vice versa. Knowing which number you are looking at prevents you from confusing a strong sales quarter with genuine profitability.
The clearest way to understand profit metrics is to follow the money down the income statement. We will use Apple's Q1 FY2026 results (the quarter ending December 2025) as a real-world walkthrough.
Step 1 — Revenue: $143.8 billion. This is the starting point. Every dollar Apple collected from customers worldwide during the quarter.
Step 2 — Cost of Revenue: $74.5 billion. These are the direct costs of producing Apple's products and delivering its services — component costs, manufacturing, freight, and data-center expenses for services. Subtracting this from revenue gives us gross profit.
Step 3 — Gross Profit: $69.2 billion (48.2% gross margin). Nearly half of every dollar Apple earned remained after covering the direct cost of goods. A 48.2% gross margin is exceptionally strong and reflects Apple's pricing power and high-margin services business.
Step 4 — Operating Expenses: $18.4 billion. Apple spent $10.9 billion on research and development and $7.5 billion on selling, general, and administrative expenses (SGA). These are the costs of running the business beyond production — engineering salaries, marketing, corporate overhead, and legal.
Step 5 — Operating Income: $50.9 billion (35.4% operating margin). After subtracting operating expenses from gross profit, Apple retained an operating margin above 35%. This metric is often considered the best indicator of core business performance because it excludes financing decisions and tax strategies.
Step 6 — Net Income: $42.1 billion (29.3% net margin). After taxes, interest, and other non-operating items, Apple kept $42.1 billion in pure profit. This is the "earnings" figure that headlines reference and the number used to calculate earnings per share.
Earnings per share (EPS) takes the net income figure and divides it by the number of shares outstanding, giving investors a per-share view of profitability. There are two flavors: basic EPS (net income divided by shares outstanding) and diluted EPS (which accounts for stock options and convertible securities that could create additional shares). Diluted EPS is the more conservative and widely quoted figure.
For Q1 FY2026, Apple reported diluted EPS of $2.85. That means for every share of AAPL stock, Apple generated $2.85 in net profit during the quarter. Across the full fiscal year 2025 (ending September 2025), Apple's total diluted EPS was approximately $7.91, reflecting the sum of all four quarters.
The quarterly EPS trend above reveals Apple's pronounced seasonality. Q1 (the holiday quarter ending in December) consistently delivers the highest EPS because of strong iPhone and holiday gift sales, while Q3 (ending in June) tends to be the weakest. Understanding this pattern is critical — comparing Q1 EPS to Q3 EPS without adjusting for seasonality would be misleading.
Why do "earnings beats" move stock prices? Before each earnings report, Wall Street analysts publish consensus EPS estimates. When a company reports EPS above that consensus — even by just a few cents — it is called an "earnings beat," and the stock often rises. Conversely, an "earnings miss" can trigger a selloff. The reaction is not purely about the absolute number; it is about whether the company exceeded or fell short of the market's expectations.
This is why you will sometimes see a company report record profits and watch its stock fall — if analysts expected even higher profits, the market treats the result as a disappointment. The expectations game is as important as the actual numbers.
Beyond the standard income-statement layers, you will frequently encounter EBITDA — earnings before interest, taxes, depreciation, and amortization. EBITDA starts with operating income and adds back depreciation and amortization (non-cash charges that reduce reported profit but do not represent actual cash leaving the business).
Why do companies highlight EBITDA? There are several legitimate reasons:
Capital-intensive businesses like telecommunications, airlines, and manufacturing carry large depreciation charges. EBITDA strips those out so investors can compare operating cash generation across firms with different asset bases.
Leveraged companies with significant debt loads use EBITDA to show profitability before financing costs, which can vary widely depending on a company's capital structure.
Acquisition analysis often relies on enterprise value to EBITDA (EV/EBITDA) multiples because EBITDA is capital-structure-neutral, making it easier to compare potential acquisition targets.
However, EBITDA has well-known limitations. Warren Buffett has famously criticized the metric, noting that depreciation is a real economic cost — machinery wears out and must be replaced. A company that reports strong EBITDA but requires massive capital expenditures to sustain its operations may be less profitable than it appears.
Other metrics you may encounter:
Free cash flow (FCF): Net income adjusted for non-cash charges and capital expenditures. Many investors consider FCF the truest measure of profitability because it reflects actual cash the business generates after maintaining its asset base.
Adjusted earnings: Companies sometimes report "non-GAAP" or "adjusted" earnings that exclude one-time charges like restructuring costs or legal settlements. These can be informative but should be scrutinized — some companies habitually label recurring costs as "one-time" to inflate adjusted figures.
Operating cash flow: Cash generated from core operations, found on the cash-flow statement rather than the income statement. It bridges the gap between accrual-based earnings and actual cash movement.
The key takeaway is that no single profit metric tells the whole story. Each one answers a slightly different question, and sophisticated investors look at several metrics together to build a complete picture.
Now that you understand the hierarchy of profitability, here is how to apply these metrics in practice.
1. The Price-to-Earnings (PE) Ratio
The PE ratio divides the current stock price by annual EPS. With AAPL trading at $264.18 and trailing twelve-month EPS around $7.91, Apple's PE ratio sits at approximately 33.4. That means investors are paying $33.40 for every $1 of Apple's annual earnings. Whether that is expensive or cheap depends on growth expectations, interest rates, and what comparable companies trade at. A high PE suggests the market expects strong future earnings growth; a low PE may signal either a bargain or a company in decline.
Apple's current market capitalization of approximately $3.88 trillion reflects the market's collective valuation of all those future earnings streams. The PE ratio is the simplest tool for checking whether that valuation is reasonable relative to current profitability.
2. Comparing Profit Margins Across Companies
Profit margins are most useful when comparing companies within the same industry. Apple's 29.3% net margin in Q1 FY2026 is remarkable for a hardware company, driven largely by its high-margin services segment. Comparing that margin to a direct competitor tells you which company converts revenue into profit more efficiently. However, comparing Apple's margins to those of a bank or an airline would be meaningless because different industries operate with fundamentally different cost structures.
3. Tracking Margin Trends Over Time
A single quarter's margin is a snapshot. What matters more is the trend. Apple's gross margin expanded from 47.2% in Q4 FY2025 to 48.2% in Q1 FY2026, suggesting improving product mix or pricing power. Similarly, the net margin rose from 26.8% to 29.3%. Consistent margin expansion over several quarters is a strong positive signal; persistent contraction is a warning sign regardless of headline revenue growth.
4. Red Flags to Watch For
Revenue growing while net income shrinks. This means costs are rising faster than sales — a potential sign of deteriorating competitive position or poor expense management.
Widening gap between GAAP and non-GAAP earnings. If a company's "adjusted" earnings are consistently and significantly higher than its GAAP (standard accounting) earnings, investigate what is being excluded and whether those exclusions are truly one-time.
Negative free cash flow despite positive net income. This can indicate that reported earnings are being propped up by accounting choices rather than genuine cash generation.
Declining margins in a growing market. If a company is gaining revenue but losing margin in an expanding market, it may be buying growth through unsustainable discounting.
5. Build a Habit of Reading the Full Income Statement
Headline EPS numbers are just the starting point. Make it a practice to pull up the full income statement and trace the waterfall from revenue through each layer of profit. It takes five minutes and reveals far more than any single number ever could.
