How to calculate a stock's intrinsic value (fair value)
Intrinsic value is what a stock is worth based on the business itself, independent of its current price. To estimate it, pick a valuation method that fits the company, feed it your own assumptions, and calculate a per-share figure you can compare to the market. The most common method is a discounted cash flow, which values the company as the present value of its future free cash flow. You can cross-check that with comparable-company multiples or, for steady dividend payers, a dividend discount model. Because every method rests on assumptions that may be wrong, seasoned investors only act when price sits well below their estimate, a cushion called the margin of safety.

How to estimate intrinsic value, step by step
- Pick a valuation method suited to the company: a DCF for most cash-generating businesses, a dividend discount model for stable payers, or an asset-based approach for balance-sheet-heavy firms.
- Gather the inputs the method needs and turn them into your own assumptions about growth, margins, and risk.
- Run the calculation to produce a per-share intrinsic value, the number the business is worth on your assumptions.
- Cross-check it with a second method, usually comparable-company multiples, to see whether the two roughly agree.
- Compare your estimate to the current market price, and require a margin of safety before treating a gap as an opportunity.
There is no single formula that spits out the true worth of a company. Intrinsic value is an estimate, and the honest version of the exercise is a range, not a point. Two careful analysts can value the same stock differently and both be reasonable, because they are making different assumptions about the future.
Using two methods is not busywork. When a DCF and a comps read land close together, you can hold the estimate with more confidence. When they diverge sharply, the disagreement is the finding: something in your cash-flow assumptions or your peer group deserves another look before you trust either number.
Which method fits which company
| Method | Fits | Core idea |
|---|---|---|
| Discounted cash flow | Companies with predictable free cash flow | Present value of the cash the business will generate |
| Comparable companies | Firms with clear public peers | What the market pays for similar businesses today |
| Dividend discount model | Mature, steady dividend payers | Present value of the future dividend stream |
| Asset-based | Balance-sheet-heavy or distressed firms | The net value of assets minus liabilities |
Match the method to the business, not the other way around. A DCF strains on a company whose cash flows are wildly unpredictable, and a dividend discount model is useless on a company that pays no dividend. Forcing a method onto a company it does not suit is the fastest way to a confident, wrong number.
Most investors lean on a DCF for the main estimate and use comps as a reality check, because the two answer different questions. The DCF asks what the future cash is worth; comps ask what the market pays for peers now. Where they agree, you have a firmer footing.
Comparing intrinsic value to price
An intrinsic-value estimate only matters next to the price. If your figure sits well above the market price, the stock may be undervalued; if well below, expensive. The gap is not a guarantee, because your estimate could be wrong, which is why value investors demand a margin of safety before buying.
The margin of safety is the discount you require to protect against your own error. Buy a stock you value at 100 dollars only in the 60s or 70s, and a mistake in your assumptions still leaves room before you lose money. The bigger your uncertainty about the business, the wider that discount should be.
This is also why chasing the last decimal of an estimate misses the point. If a company is only worth buying when your model is exactly right, it is not worth buying. The margin of safety is what turns a fuzzy estimate into a decision you can defend.
Estimating fair value in Brief Equity
Brief Equity models estimate fair value from your own assumptions rather than handing you a number. You build a DCF and an EV/EBITDA model, drag any input, and the per-share value recomputes as you go. Base starts on the latest analyst consensus, so your first estimate begins from a real anchor instead of a blank page.
Because fair value is a range, the tool leans into that. Keep Bear, Base, and Bull scenarios side by side, then push them further with a sensitivity view across two drivers or a Monte Carlo run that plots the full spread of outcomes. The result is a band of values with the assumptions behind each one visible, which is closer to how the estimate actually behaves than a single figure.

What is intrinsic value (fair value)
Intrinsic value is an estimate of what a business is really worth from its fundamentals, separate from its share price. Comparing the two is the core of value investing.

Frequently asked questions
- What is the best way to calculate intrinsic value?
- For most companies a discounted cash flow is the standard approach, since it values a business on the cash it generates. It works best alongside a second method, usually comparable-company multiples, as a cross-check. There is no single correct method; the right one depends on the company.
- Is intrinsic value the same as fair value?
- In everyday use they are treated as the same idea: an estimate of what a stock is worth based on the business rather than its market price. Both are estimates, not facts, and reasonable investors can arrive at different figures for the same company.
- How is intrinsic value different from market price?
- Market price is what the stock trades at right now, set by supply and demand. Intrinsic value is your estimate of what the business is worth on its fundamentals. Value investing is built on the gap between them: buying when price is well below your estimate.
- Why do I need a margin of safety?
- Because any intrinsic-value estimate can be wrong. Buying only when the price sits well below your estimate leaves room for error in your assumptions. The less certain you are about the business, the wider that discount should be before you act.
