Stock Intrinsic Value Calculator: 5 Methods and How to Use Them
April 6, 2026 · Investing Fundamentals · 9 min read
Intrinsic value is what a stock is actually worth — independent of what the market currently prices it at. Calculating it is the foundation of value investing, and it's also one of the most misunderstood concepts in retail investing.
This article explains five methods for calculating intrinsic value, provides the formulas and worked examples for each, explains why single-method calculators are incomplete, and shows how to build a consensus intrinsic value estimate that holds up under scrutiny.
What Is Intrinsic Value?
Intrinsic value is the present value of all future cash flows a business will generate over its lifetime, discounted back to today at a rate that reflects the risk of those cash flows not materialising.
It is different from:
- Book value — the accounting value of assets minus liabilities (a backward-looking measure)
- Market price — what the market is currently willing to pay (which may be more or less than intrinsic value)
- Liquidation value — what the assets would sell for if the company were shut down tomorrow
The gap between intrinsic value and market price is the margin of safety — the cushion that protects you when your assumptions turn out to be too optimistic.
Method 1: Discounted Cash Flow (DCF)
The DCF is the theoretically correct intrinsic value calculator. It values a business based on the present value of its future free cash flows.
Formula:
Intrinsic Value = S [FCF_t / (1 + r)^t] + Terminal Value / (1 + r)^n
Terminal Value = FCF_n — (1 + g) / (r - g)
Where:
- FCF_t = Free cash flow in year t
- r = Discount rate (your required rate of return, typically 8–10%)
- g = Terminal growth rate (typically 2–3%, linked to long-run GDP growth)
- n = Forecast period (typically 5–10 years)
Worked example: A company generates $5 per share in free cash flow today. You assume 8% annual FCF growth for 5 years, a 3% terminal growth rate, and a 9% discount rate.
Year 1: $5.40 / 1.09 = $4.95 Year 2: $5.83 / 1.09× = $4.91 ... Year 5: $7.35 / 1.095 = $4.77
Terminal Value (at year 5): $7.35 × 1.03 / (0.09 - 0.03) = $126.18, discounted = $82.00
Sum of years 1–5 — $24.00 Intrinsic Value — $24.00 + $82.00 = $106 per share
Limitation: The DCF is highly sensitive to the growth rate and discount rate assumptions. A 1% change in the discount rate can shift intrinsic value by 20–30%.
Method 2: Benjamin Graham's Intrinsic Value Formula
Benjamin Graham, the father of value investing, proposed a simplified intrinsic value formula for defensive investors who don't want to model full DCF projections.
Formula (original):
Intrinsic Value = EPS — (8.5 + 2g)
Updated formula (adjusted for yield environment):
Intrinsic Value = EPS — (8.5 + 2g) — (4.4 / Y)
Where:
- EPS = Current earnings per share
- g = Expected annual EPS growth rate over the next 7–10 years (as a percentage, not decimal)
- Y = Current yield on AAA corporate bonds (4.4 was the AAA yield when Graham published)
- 8.5 = Base P/E for a zero-growth company
Worked example: A company has EPS of $4.00, expected growth of 10%, and AAA bond yield is 5.5%.
Intrinsic Value = $4.00 × (8.5 + 20) × (4.4 / 5.5) = $4.00 × 28.5 × 0.80 = $91.20 per share
Limitation: The formula assumes linear growth and doesn't account for capital intensity, quality of earnings, or reinvestment requirements.
Method 3: Graham Number
The Graham Number is a simpler screen for conservative investors. It calculates the maximum price a defensive value investor should pay.
Formula:
Graham Number = v(22.5 — EPS — Book Value Per Share)
The 22.5 multiplier reflects Graham's rule of thumb: no more than 15× earnings and no more than 1.5× book value (15 × 1.5 = 22.5).
Worked example: EPS = $6.00, Book Value Per Share = $40.00
Graham Number = v(22.5 — 6 × 40) = v5,400 = $73.48
If the stock is trading at $55, it's trading at a 25% discount to the Graham Number.
Limitation: The Graham Number works best for traditional asset-heavy businesses (banks, industrials, consumer staples). It undervalues capital-light businesses (software, platforms) where book value substantially understates intrinsic worth.
Method 4: Earnings Power Value (EPV)
EPV calculates intrinsic value assuming the business maintains its current earnings power with zero growth. It answers: "What is this business worth if it never grows again?"
Formula:
EPV = Normalised EBIT — (1 - Tax Rate) / WACC
Where:
- Normalised EBIT = Adjusted operating income, smoothed over a business cycle to remove one-time items
- Tax Rate = Effective corporate tax rate
- WACC = Weighted average cost of capital (typically 8–12%)
Worked example: Normalised EBIT = $500M, Tax Rate = 21%, WACC = 9%
EPV = $500M — (1 - 0.21) / 0.09 = $395M / 0.09 = $4.39B
If the current enterprise value is $3.5B, the stock is trading below its no-growth intrinsic value — a conservative signal.
Why EPV is useful: It separates the value of existing operations from the value of expected growth. Growth only adds intrinsic value if the return on invested capital (ROIC) exceeds the cost of capital. EPV is the "floor" of intrinsic value for a business that can sustain current operations.
Method 5: Dividend Discount Model (DDM)
The DDM calculates intrinsic value as the present value of all future dividends. It is most applicable to dividend-paying companies with stable payout histories.
Gordon Growth Model (perpetuity DDM):
Intrinsic Value = D1 / (r - g)
Where:
- D1 = Expected dividend in the next 12 months
- r = Required rate of return
- g = Expected perpetual dividend growth rate
Worked example: Current annual dividend = $2.00, expected growth = 5%, required return = 9%
D1 = $2.00 × 1.05 = $2.10
Intrinsic Value = $2.10 / (0.09 - 0.05) = $2.10 / 0.04 = $52.50
Limitation: The DDM fails for companies that pay no dividend or that reinvest earnings for growth (most technology companies). It is also hypersensitive to the growth rate assumption: if g approaches r, intrinsic value approaches infinity.
Why Single-Method Calculators Fail
Each of the five methods captures a different aspect of intrinsic value:
| Method | What It Measures | Works Best For |
|---|---|---|
| DCF | Present value of future cash flows | Most businesses with predictable cash flows |
| Graham Formula | Conservative growth-adjusted earnings value | Mid-cap value stocks |
| Graham Number | Maximum defensive price | Asset-heavy traditional businesses |
| EPV | No-growth operational value | Established businesses, floor valuation |
| DDM | Present value of dividend stream | Dividend-paying mature companies |
No single method is universally applicable. Running only a DCF on a bank produces misleading results (banks use debt as raw material, making FCF ill-defined). Running only the DDM on Amazon produces no result at all (no dividend).
A robust intrinsic value calculation runs 4–6 applicable methods and synthesises them into a consensus range.
Building a Consensus Intrinsic Value
Step 1 — Select applicable methods. Discard methods that don't fit the business model (e.g., DDM for non-dividend payers, Graham Number for pure software businesses).
Step 2 — Calculate each method. Use the formulas above, with current financial data.
Step 3 — Review for outliers. If five methods cluster around $80–$100 and one says $150, understand why before including it at full weight.
Step 4 — Calculate a weighted average. Weight methods by their applicability to the specific business and the quality of the underlying inputs.
Step 5 — Calculate the margin of safety. The margin of safety tells you how much you're paying relative to consensus intrinsic value.
Margin of Safety (%) = (Intrinsic Value - Current Price) / Intrinsic Value — 100
A stock with a $100 consensus intrinsic value trading at $75 has a 25% margin of safety. A stock trading at $120 has a -20% margin of safety (you're paying a 20% premium to consensus fair value).

Running five methods manually requires current financial data, updated estimates, and meaningful time per stock. For a watchlist of 20 stocks, that's a significant undertaking — and the data is stale within weeks.
Equity Rank calculates intrinsic value using eight methods on 500+ stocks daily using live financial data. The output includes:
- Consensus fair value (weighted average across applicable methods)
- Margin of safety percentage
- SAVE score (adds sentiment, analyst consensus, and earnings quality signals to the pure valuation picture)
The screener lets you filter by margin of safety threshold — for example, showing only stocks with a 20%+ margin of safety and a SAVE score above 60.
