How to Calculate the Intrinsic Value of a Stock (Step-by-Step)
# How to Calculate the Intrinsic Value of a Stock (Step-by-Step)
Intrinsic value is the estimated true worth of a stock based on fundamentals — independent of its current market price. If the market price is below intrinsic value, the stock may be undervalued. If it's above, it may be overpriced.
This guide walks through the main methods used by fundamental analysts and value investors.
## What Is Intrinsic Value?
Intrinsic value attempts to answer one question: what is this business actually worth?
It is not the same as market price. Market price reflects what buyers and sellers agree on at a given moment. Intrinsic value reflects what the business is worth based on its ability to generate cash over time.
The concept was formalized by Benjamin Graham and David Dodd in Security Analysis (1934) and remains the foundation of value investing today.
## Method 1: Discounted Cash Flow (DCF)
The DCF model is the most widely used method for estimating intrinsic value. It calculates the present value of a company's expected future free cash flows.
### The Formula
Intrinsic Value = Sum of [FCF_t / (1 + r)^t] + Terminal Value / (1 + r)^n
Where:
- FCF_t = Free cash flow in year t
- r = Discount rate (usually WACC)
- n = Number of projection years
- Terminal Value = FCF_n × (1 + g) / (r - g)
- g = Long-term growth rate
### Step-by-Step
**Step 1 — Estimate future free cash flows.** Start from the most recent trailing twelve months (TTM) FCF. Project it forward 5 to 10 years using a realistic growth rate based on historical performance, industry trends, and management guidance.
**Step 2 — Choose a discount rate.** The discount rate reflects the risk of the investment. Most analysts use the Weighted Average Cost of Capital (WACC), which typically ranges from 8% to 12% for US equities. Higher risk = higher discount rate = lower intrinsic value.
**Step 3 — Calculate terminal value.** After the projection period, assume the business continues growing at a stable long-term rate (usually 2% to 3%, in line with GDP). Use the Gordon Growth Model: Terminal Value = FCF × (1 + g) / (r - g).
**Step 4 — Discount everything back to today.** Apply the discount rate to each year's FCF and to the terminal value. Sum them all.
**Step 5 — Adjust for net cash and shares outstanding.** Add net cash (or subtract net debt) to get equity value. Divide by shares outstanding to get intrinsic value per share.
### Example
A company generates $500M in FCF. You project 10% growth for 5 years, then apply a 3% terminal growth rate and a 10% discount rate.
Year 1: $550M / 1.10 = $500M
Year 2: $605M / 1.21 = $500M
Year 3: $665M / 1.33 = $500M
Year 4: $732M / 1.46 = $501M
Year 5: $805M / 1.61 = $500M
Terminal Value = $805M × 1.03 / (0.10 - 0.03) = $11,844M
PV of Terminal Value = $11,844M / 1.61 = $7,358M
Total equity value = ~$10,000M + net cash
Divide by shares outstanding to get per-share intrinsic value.
## Method 2: Earnings-Based Valuation (EPS × P/E)
A simpler approach commonly used for stable, mature businesses.
Intrinsic Value = Normalized EPS × Fair P/E Multiple

**How to apply it:**
1. Calculate normalized EPS — average earnings per share over a full business cycle (typically 5–7 years) to remove cyclical distortions.
2. Assign a fair P/E multiple based on the company's historical average, industry peers, and growth expectations.
3. Multiply.
**Example:** A company has normalized EPS of $4.00. You assign a fair P/E of 18x (in line with its 10-year average). Intrinsic value = $72.
This method is fast but sensitive to earnings quality. Avoid using it for companies with volatile or heavily adjusted earnings.
## Method 3: Asset-Based Valuation
Used primarily for holding companies, banks, real estate firms, or businesses in liquidation.
Intrinsic Value ≈ Net Asset Value (NAV) = Total Assets − Total Liabilities
For asset-heavy businesses, this sets a floor on value. For growth companies with few tangible assets, it is largely irrelevant.
## Which Method Should You Use?
There is no single correct method. Serious analysts use multiple methods and triangulate.
- **DCF** is best for companies with predictable, growing cash flows (e.g. software, consumer staples).
- **Earnings-based** works well for mature, stable businesses with consistent margins.
- **Asset-based** is most relevant for financial companies, holding companies, or distressed situations.
When the three methods converge on a similar number, confidence is higher. When they diverge significantly, it is a signal to investigate why.
## Common Mistakes
**Using a single scenario.** Intrinsic value is not a single number — it is a range. Always model a base case, a bull case, and a bear case with different assumptions.
**Being too precise.** A DCF that outputs $47.32 per share is false precision. The output is only as good as the assumptions. A range of $40–$55 is more honest.
**Ignoring qualitative factors.** Moat, management quality, competitive dynamics, and regulatory risk are not in the spreadsheet but materially affect future cash flows.
**Using GAAP net income instead of free cash flow.** Net income includes non-cash items and accounting adjustments. Free cash flow — cash from operations minus capex — is a cleaner measure of what the business actually generates.
**Setting the terminal growth rate too high.** A terminal growth rate above 3–3.5% implies the company will eventually be larger than the entire economy. It rarely makes sense.
## The Margin of Safety
Benjamin Graham's core principle: only buy when the market price is significantly below intrinsic value — typically 20% to 40% below. This buffer absorbs errors in your estimates.
Intrinsic value calculation is inherently uncertain. The margin of safety is not optional — it is the mechanism that makes value investing work despite imprecise inputs.
