Every investor eventually asks the same question: "Is this stock cheap or expensive?" But cheap and expensive compared to what? That's the problem price alone can't answer.
Intrinsic value is your estimate of what a business is actually worth — independent of what the market currently charges for it.
Understanding intrinsic value doesn't require a finance degree. It requires one shift in how you think about what you're buying.
Price is what you pay; value is what you get
When you buy a stock, you're buying a small ownership stake in a real business. That business earns money, reinvests it, and eventually — through dividends, buybacks, or a future sale — returns that money to owners like you.
The price is what the stock market is willing to sell that stake for today. It changes by the minute. The value is what that stream of future cash is genuinely worth.
These two numbers are often close. Sometimes they're far apart. The gap is where investing decisions live.
Where intrinsic value comes from
Think about a rental property. If a house generates $12,000/year in rent after expenses, you might be willing to pay $200,000 for it — roughly 16–17 times annual income. At $300,000 you'd hesitate. At $150,000 you'd buy immediately.
A business works the same way. Its intrinsic value is the present value of all the cash it will ever produce for its owners. The two inputs that matter most:
- How much cash will the business generate each year?
- How confident are you in that estimate?
The less certain you are, the more discount you apply. A predictable utility business might be worth 18–22 times its earnings. A volatile startup might be worth 8–10 times — or nothing, if you can't estimate future cash flows at all.
A worked example
Imagine a company called NoteApp Co. It earns $2 per share in free cash flow — real cash left over after running the business and reinvesting in growth. You believe it'll keep earning at roughly this level for many years.
A simple way to estimate intrinsic value: multiply by a reasonable price-to-earnings multiple. At 15× earnings (a conservative figure for a stable business), you get an intrinsic value of about $30 per share.
If the stock is trading at $22, you're buying at a discount. If it's trading at $45, you're paying a premium — you'd need fast growth to justify it.
This is why intrinsic value matters: it gives you an anchor. Without one, any price can feel cheap or expensive depending on market mood.
Why estimates differ
No two investors will calculate exactly the same intrinsic value for the same business — and that's expected. The calculation requires judgment calls:
- How fast will earnings grow?
- How long can the company sustain its competitive advantage?
- What discount rate is appropriate?
The goal isn't a single precise number. It's a range. If NoteApp Co. is worth somewhere between $25 and $35 per share, and it's trading at $18, you have a [margin of safety](/published/investing-research/what-is-a-margin-of-safety.md) — a cushion that protects you if your estimate turns out to be optimistic.
Why it matters for your research
Intrinsic value is the organizing concept behind your [investment thesis](/published/investing-research/what-is-an-investment-thesis.md). Before you write "I'm buying this," you need to answer: "And I believe it's worth roughly X, which is Y% above the current price."
Without that number, you can't reason about when to buy, when to sell, or when you were wrong. With it, every piece of research you do has a direction: you're either refining your estimate of future cash flows or testing your assumptions about competitive position.
[Free cash flow](/published/investing-research/what-is-free-cash-flow.md) and [economic moats](/published/investing-research/what-is-an-economic-moat.md) are the two most important inputs into an intrinsic value estimate. Once you understand all three together, fundamental investing starts to feel like a coherent system rather than a collection of separate metrics.
Try this
Pick a business you know well — your employer, a company you've been a customer of for years, a franchise you pass every day. Without looking at its stock price, answer: "How much cash do I think this business earns per year, per unit of ownership?" Then: "What would I pay for that cash stream?"
Now look up the current stock price. The gap between your estimate and the market price is exactly where an investing opinion lives.
In JustJot.ai, capture this as a short research note: "I estimate [company] earns roughly [X] per share. At [multiple]× that's [intrinsic value estimate]. Current price: [Y]." Three months from now, come back and test your assumptions. That note — more than any market prediction — is what separates research from guessing.
