The income statement answers one question: over the year, did the company make money, and from what? It reads top to bottom like a funnel — money in at the top, costs subtracted in stages, profit at the bottom.
Revenue (also called sales, or the “top line” because it sits at the top) is the total money the company brought in from selling its products or services. Example (illustrative): our company reports $100 million in revenue for the year. That’s the widest part of the funnel — everything below is a subtraction.
Cost of revenue (or cost of goods sold) is what it cost to produce what was sold — materials, factory labor, the direct costs. Subtract it from revenue and you get gross profit. Example (illustrative): $100M revenue minus $60M cost of revenue leaves $40M gross profit, a gross margin of 40% (gross profit divided by revenue). A higher gross margin means the company keeps more of each sales dollar after production — useful for comparing two companies in the same industry.
Running a business costs more than making the product: salaries for non-factory staff, marketing, rent, research. These are operating expenses. Subtract them from gross profit and you get operating income — profit from the core business, before financing and taxes. Example (illustrative): $40M gross profit minus $25M operating expenses leaves $15M operating income.
Take out interest on debt and taxes and you reach net income — the “bottom line,” the actual profit. Example (illustrative): $15M operating income minus $3M interest and taxes leaves $12M net income. Divide net income by shares outstanding and you get earnings per share (EPS) — profit attributable to each share. Example (illustrative): $12M over 10 million shares is an EPS of $1.20. EPS is the number that feeds the P/E ratio you see everywhere.
One year’s numbers are a snapshot; the story is in the change. Compare this year’s revenue and EPS to last year’s — that’s exactly what revenue growth (year-over-year) and EPS growth measure, and both appear on a company’s page here on Quantustik. A company growing revenue but shrinking profit is spending more to sell more; one growing EPS faster than revenue is getting more efficient. Reading the income statement yourself means you know what those metrics are made of — instead of trusting a single headline that could be flattered by a one-time gain buried in the notes.
This lesson is investor education, not personalized advice. The worked figures are illustrative, not any real company’s results, and nothing here is a buy signal. No forecasting tool, including Quantustik, promises a return.
Revenue is the total money that came in from sales (the top line). Net income is what’s left after every cost — production, operating expenses, interest, and taxes — the bottom line. A company can have large revenue and small or negative net income.
Earnings per share (EPS) is net income divided by the number of shares outstanding — the profit attributable to each share. It’s the earnings figure that feeds the P/E ratio.
One year is a snapshot; the trend tells the story. Comparing revenue and EPS year over year shows whether the business is growing, and whether profit is keeping pace with sales — the basis of the revenue-growth and EPS-growth metrics.
Investor education only — not investment advice, and never a promise of profit. Every investment can lose value.
