How Companies Make Money
Fundamental analysis starts with a simple but profound question: How does this business actually make money? Before looking at complex ratios, you must understand the "Revenue Model"-the specific mechanism a company uses to capture value from its customers.1
In the 2026 economy, companies rarely rely on a single method; they often stack multiple "revenue streams" to create a more resilient business.2
1. The Core Revenue Models
Most businesses fall into one or more of these foundational categories:
- Transactional Model (Product Sales): The oldest and simplest form.3 A customer pays once, receives a product or service, and the transaction is complete (e.g., Apple selling an iPhone or Nike selling shoes).4
- Subscription Model: Customers pay a recurring fee (monthly or annually) for ongoing access.5 This is the "holy grail" for investors because it creates predictable, recurring revenue (e.g., Netflix, Microsoft 365, or a gym membership).6
- Advertising Model: The company provides a "free" service to users and makes money by selling the users' attention to advertisers (e.g., Google Search, Meta/Facebook, or YouTube).7
- Commission / Brokerage Model: The company acts as a middleman, taking a percentage of every transaction that happens on its platform (e.g., Airbnb, Uber, or a stockbroker).8
- Markup Model: Common in retail and wholesale.9 The business buys a product at a lower cost and sells it at a higher price (e.g., a grocery store or a car dealership).10
2. Operating vs. Non-Operating Revenue
To judge a company's health, you must distinguish between its "Bread and Butter" and its "Side Hustles".
Type | Definition | Example |
|---|---|---|
Operating Revenue | Money earned from the core business. | For Starbucks, this is selling coffee and food. |
Non-Operating Revenue | Income from secondary activities outside the main business. | For Starbucks, this might be interest earned on its cash balance or selling an old piece of real estate. |
Fundamental Insight: High non-operating revenue can sometimes "hide" a struggling core business. Investors look for consistent growth in Operating Revenue.
3. Case Study: The "Hybrid" Approach (Amazon)
Modern giants like Amazon use almost every revenue model simultaneously to dominate the market:
- Transactional: Selling a book or a toaster.
- Subscription: Amazon Prime memberships.11
- Commission: Fees charged to "Third Party" sellers on the platform.
- Service (Usage-Based): Amazon Web Services (AWS) where you pay for what you use.12
- Advertising: Charging brands to be "Sponsored Products" in search results.
4. Revenue vs. Profit: The Critical Distinction
Making money (Revenue) is not the same as keeping money (Profit). A company can have billions in revenue but still go bankrupt if its "Cost of Goods Sold" (COGS) and "Operating Expenses" (Rent, Salaries, Marketing) are higher than what it brings in.
- Gross Profit: Revenue minus the direct cost of making the product.13
- Net Profit: The "Bottom Line"-what’s left after every expense, including taxes, is paid.14
