Intrinsic Value: How to Calculate What a Stock Is Really Worth
A stock at $50 might have an intrinsic value of $75 based on discounted future cash flows. Buying at $50 with a $75 intrinsic value gives you a 33% margin of safety. If you're wrong about some assumptions, the margin of safety protects you. Here's how to calculate intrinsic value.
Intrinsic value is the true underlying worth of a stock based on its fundamental characteristics — earnings power, growth potential, asset base, and competitive advantages — independent of the current market price. Benjamin Graham, the father of value investing, defined intrinsic value as "the value that is justified by the facts" including assets, earnings, dividends, and definable prospects. The market price is what you pay; intrinsic value is what you get. When market price falls significantly below intrinsic value, the stock offers a margin of safety. The challenge is that intrinsic value cannot be calculated with precision — it exists on a range, not as a single number. Every valuation method requires assumptions about the future. The goal is not perfect accuracy but a reasonable estimate that identifies when the market is dramatically mispricing a stock. Learn DCF analysis →
Real-world example: In early 2025, Meta Platforms (META) traded around $480 per share. A DCF analysis using 12% revenue growth for 5 years, a 10% WACC, and a 3% terminal growth rate produced an intrinsic value of approximately $620-680 per share, suggesting the stock was undervalued. By mid-2025, the stock had risen to $580, narrowing the margin of safety but still below intrinsic estimates. This illustrates how intrinsic value serves as an anchor — the market price may bounce around, but the intrinsic value changes only when the underlying business fundamentals change.
How to Calculate Intrinsic Value
Discounted Cash Flow (DCF) Analysis
DCF is the most academically rigorous method for calculating intrinsic value. It projects a company's future free cash flows and discounts them back to present value using an appropriate discount rate (usually WACC). The formula is: Intrinsic Value = Sum of Present Value of Projected Free Cash Flows + Present Value of Terminal Value. Free cash flow is the cash a business generates after maintaining its asset base — the cash available to shareholders and debt holders. The discount rate reflects the riskiness of those cash flows: higher risk means a higher discount rate and lower present value. The terminal value captures the value of cash flows beyond the projection period, usually 5-10 years. Terminal value often represents 60-80% of the total DCF value, making the terminal growth assumption critically important. A DCF model is only as good as its assumptions. Small changes in revenue growth, margins, discount rate, or terminal growth produce dramatically different intrinsic values. Use sensitivity analysis to test your assumptions.

Comparable Company Analysis (Comps)
Comps estimates intrinsic value by comparing the target company to similar publicly traded companies using valuation multiples. Common multiples include P/E (price-to-earnings), EV/EBITDA, P/S (price-to-sales), and P/B (price-to-book). The logic is simple: if comparable companies trade at an average of 15x earnings, and the target company earns $5 per share, its intrinsic value might be $75 (15 x $5). Comps are useful because they reflect real market transactions and current sentiment. However, comps assume the market is pricing comparable companies correctly — if the entire sector is overvalued, comps will produce an inflated intrinsic value. Comps also require careful selection of truly comparable companies with similar growth rates, margins, risk profiles, and capital structures. Adjustments for differences in size, growth, and profitability improve accuracy. Most analysts use a range of multiples to produce an intrinsic value range rather than a single point estimate.

Asset-Based Valuation
Asset-based valuation calculates intrinsic value as the net value of a company's tangible assets minus liabilities. This approach works best for holding companies, natural resource firms, financial institutions, and distressed businesses where the value of the assets can be reasonably estimated. The formula is: Intrinsic Value = Total Assets (at market value) - Total Liabilities. This differs from book value because you replace accounting values with estimated market values for each asset. Real estate, securities, and commodity reserves are marked to market. Patents and brand value may be included if they have estimable market value. Asset-based valuation provides a floor value for a business — the minimum the company is worth if liquidated. For a going concern, intrinsic value usually exceeds asset value because the business can generate returns above its asset base. When a stock trades below asset-based intrinsic value, it may attract activist investors or private equity buyers seeking a liquidation or restructuring play. Analyze assets on the balance sheet →
What is margin of safety?
Margin of safety is the difference between a stock's intrinsic value and its market price, expressed as a percentage. If a stock's intrinsic value is $100 and it trades at $70, the margin of safety is 30%. Benjamin Graham insisted on a large margin of safety because intrinsic value is an estimate, not a precise number. A large margin of safety protects against errors in your assumptions, bad luck, and unforeseeable events. The required margin of safety varies with the quality and predictability of the business. A stable utility with predictable cash flows might warrant a 20% margin of safety. A cyclical commodity producer with volatile earnings might require a 50% margin. In the current market environment, with low interest rates and high valuations, finding stocks with adequate margins of safety is harder than in past decades. Investors often must look to smaller companies, international markets, or out-of-favor sectors to find significant discounts to intrinsic value.
How does intrinsic value differ from market price?
Market price is what you pay for a stock today — determined by supply and demand, news, sentiment, and trading flows. Intrinsic value is what the stock is actually worth based on its fundamental earning power, growth prospects, and asset base. Market price can deviate from intrinsic value for extended periods. During the 2020-2021 bull market, many growth stocks traded at 10-20x their intrinsic value as investors extrapolated high growth rates indefinitely. When growth slowed in 2022, market prices collapsed back toward intrinsic values. This is why Graham said: "In the short run, the market is a voting machine but in the long run, it is a weighing machine." The market price eventually converges toward intrinsic value, but the timing is unpredictable. The intrinsic value also changes over time as a company's earnings, competitive position, and growth prospects evolve. The successful investor buys when market price is well below intrinsic value and sells when market price exceeds intrinsic value.
What are the limitations of intrinsic value?
Intrinsic value has unavoidable limitations. It depends on future assumptions that are inherently uncertain: revenue growth rates, profit margins, capital requirements, discount rates, and terminal values. Small changes in any assumption can produce dramatically different values. Different analysts using the same data can arrive at intrinsic values that differ by 50% or more. Intrinsic value also changes over time as new information emerges and assumptions must be updated. It provides no timing signal — a stock can trade below intrinsic value for years before the market recognizes its true worth. Most dangerously, investors often fall in love with their own intrinsic value estimates and refuse to update them when the business deteriorates (anchoring bias). The best approach is to calculate intrinsic value using multiple methods, use ranges rather than point estimates, update assumptions regularly, and demand a large margin of safety to account for the inherent uncertainty in all valuation models.
