Discounted Cash Flow Model: An In-Depth Analysis for Serious Investors
A discounted cash flow model is a structured framework for converting a company's expected future free cash flows into a present-day intrinsic value estimate. The model is the workhorse of fundamental equity analysis. It forces you to make your growth assumptions, discount rate, and terminal value decisions explicit rather than hiding them inside a P/E multiple. This analysis goes inside the architecture of a DCF model, examines the decisions that determine whether the output is reliable, and applies the framework to real companies with real data.
The primary keyword here is intentional. A discounted cash flow model is a specific, structured tool. Understanding how it is built is different from understanding the general concept of time value of money.
Key Takeaways
- A discounted cash flow model has five components: historical free cash flow baseline, near-term projections, discount rate (WACC), terminal value, and the equity bridge to per-share intrinsic value.
- Free cash flow, not earnings, is the model input. Earnings include non-cash items and ignore capital intensity. FCF is actual cash the business generates.
- Terminal value accounts for 60-80% of most DCF model outputs. The long-term growth assumption (g) is therefore the single most consequential number in the model.
- Apple at a P/E of 28.3 with a ROIC of 45.1% illustrates how capital efficiency justifies richer DCF assumptions. Microsoft at P/E 32.1 reflects similar logic applied to cloud recurring revenue.
- A discounted cash flow model without a sensitivity table is incomplete. Every output is a range, not a single number.
What Makes a Discounted Cash Flow Model Different From a Multiple
When you apply a P/E multiple to a stock's earnings to get a target price, you are making three implicit assumptions: the current P/E is the right multiple, earnings are the right denominator, and the current multiple is appropriate for this company's risk and growth profile. None of those assumptions is made explicit. You cannot challenge them in the model.
A discounted cash flow model makes all three explicit. The growth rate is your assumption, stated and testable. The discount rate is your required return, derived from observable market data. The terminal value explicitly states what you believe the business is worth beyond your forecast horizon. Every number can be debated, changed, and sensitivity-tested.
That transparency is the strength of the DCF model. It is also why it is more work. You cannot run a DCF model in 30 seconds. You can run a P/E comparison in 30 seconds. The extra time is the cost of knowing what you actually own.
What Is Free Cash Flow
Free cash flow is the cash a business generates after paying for its operations and the capital expenditures required to maintain and grow its productive assets. The formula:
Free Cash Flow = Operating Cash Flow - Capital Expenditures
Both figures come from the statement of cash flows. Operating cash flow is in the operating section. Capital expenditures are in the investing section under "purchases of property, plant, and equipment."
The reason DCF models use free cash flow rather than net income is that net income is an accounting result, not a cash result. It includes depreciation (non-cash), amortization (non-cash), and stock-based compensation (non-cash), and it excludes the actual cash spent on capital investment. A business can show $1 billion in net income while consuming $1.5 billion in capex to stay competitive. Free cash flow surfaces that reality.
What Is the Free Cash Flow: Three Variants
Different DCF model architectures use different definitions of free cash flow. The choice affects which discount rate is appropriate and how you bridge from enterprise value to equity value.
| FCF Variant | Formula | Discount Rate Paired With | Bridge to Equity Value |
|---|---|---|---|
| Unlevered FCF (FCFF) | NOPAT + D&A - Change in NWC - Capex | WACC | Subtract net debt, add cash |
| Levered FCF (FCFE) | Operating CF - Capex - Debt Repayments | Cost of equity only | Direct equity value (no bridge needed) |
| Owner Earnings | Net Income + D&A - Maintenance Capex | WACC or cost of equity | Subtract net debt, add cash |
FCFF paired with WACC is the default for most U.S. equity DCF models. It separates the business valuation from the capital structure decision, which allows cleaner comparisons across companies with different debt levels.
Microsoft's FCFF ran to approximately $69 billion in fiscal 2024. At a P/E of 32.1, the market is pricing in the expectation that Azure and commercial cloud drive that figure materially higher over the next decade.
How to Calculate Free Cash Flow From Financial Statements
The FCFF calculation from financial statements follows this sequence:
- Start with EBIT (operating income) from the income statement.
- Multiply by (1 - effective tax rate) to get NOPAT (net operating profit after tax).
- Add depreciation and amortization (non-cash, flows back in).
- Subtract the increase in net working capital (or add the decrease). Working capital increases consume cash.
- Subtract capital expenditures.
FCFF = EBIT x (1 - Tax Rate) + D&A - Change in NWC - Capex
Applying this to Johnson & Johnson (JNJ) with approximate figures: EBIT $14.2B, tax rate 18%, D&A $3.4B, NWC increase $0.6B, capex $1.8B. FCFF = ($14.2B x 0.82) + $3.4B - $0.6B - $1.8B = approximately $12.6 billion. JNJ's dividend yield of 3.1% is directly supported by this cash generation.
How to Calculate Intrinsic Value Using a Discounted Cash Flow Model
The model has five stages. Completing all five is non-negotiable.
Stage 1: Historical FCF baseline
Pull five to ten years of data. Calculate the annual FCF for each year. Compute the 3-year and 5-year CAGR. Normalize any one-time items: litigation settlements, M&A transaction costs, one-year capex step-changes. The normalized historical CAGR is your anchor for the projection.
Stage 2: Forward projections
Use a two-stage model. Apply a higher near-term growth rate (years 1-5) and a lower rate for years 6-10. The near-term rate should be grounded in analyst consensus, management guidance, and your own assessment of the competitive position. The mid-term rate should be conservative, trending toward the range that the business can sustain given market size and competitive dynamics.
Stage 3: Discount rate
For FCFF models, use WACC. Build it from CAPM for the cost of equity component. As of early 2026, with the 10-year Treasury near 4.45% and a typical equity risk premium of 5.0%, a beta-1.0 stock carries a cost of equity of approximately 9.45%. For Apple (AAPL) with a beta near 1.2, the cost of equity runs near 10.45%.
Stage 4: Terminal value
Terminal Value = FCFn x (1 + g) / (WACC - g)
Set g between 2% and 3% for most large-cap U.S. equities. Never set g above WACC. For context: at a WACC of 9% and a g of 3%, the denominator is 6%. At a g of 4%, it drops to 5% and terminal value jumps 20%. That sensitivity is why g deserves more scrutiny than most investors give it.
Stage 5: Equity bridge
Enterprise Value = Sum of discounted FCFs + Discounted Terminal Value. Equity Value = Enterprise Value - Net Debt. Per-Share Intrinsic Value = Equity Value / Diluted Shares Outstanding.
A Simplified Common Stock Valuation Model
The full multi-stage DCF is not always necessary. For stable, mature businesses with consistent dividend histories, the Gordon Growth Model provides a rapid check:
Intrinsic Value = D1 / (r - g)
Where D1 is the next expected annual dividend, r is the required return, and g is the perpetual dividend growth rate.
For Coca-Cola (KO), with an estimated 2026 dividend of $2.00, a required return of 8%, and a historical dividend growth CAGR of 3.3%: Value = $2.00 / (0.08 - 0.033) = approximately $42.55. If KO trades materially above that figure, the implied return at the market price falls below your required rate.
This model does not replace a full DCF. It flags whether the market price is plausible given dividend fundamentals before you invest the time in a complete projection model.
How to Build a Stock Valuation Model: Sensitivity Analysis
Sensitivity analysis converts a single-point DCF output into an honest range. The two inputs with the most impact are the discount rate and the terminal growth rate.
| Discount Rate | g = 2.0% | g = 2.5% | g = 3.0% | g = 3.5% |
|---|---|---|---|---|
| 8.0% | $210 | $230 | $258 | $295 |
| 9.0% | $178 | $192 | $210 | $234 |
| 10.0% | $153 | $163 | $176 | $193 |
| 11.0% | $133 | $141 | $150 | $163 |
(Illustrative per-share values for a company with $8B current FCFF, 8% near-term growth)
The range from $133 to $295 is the honest output. Buying at a significant discount to the bear case provides a margin of safety against simultaneous errors in every assumption. For Berkshire Hathaway (BRK.B), which trades near a P/B of 1.5 as of April 2026, the margin of safety comes built into the price-to-book structure rather than requiring a full DCF.
What the DCF Model Reveals About High-ROIC Businesses
ROIC (return on invested capital) and the DCF model connect at the terminal value stage. A business with ROIC substantially above its cost of capital creates real value with each dollar reinvested. A business with ROIC equal to or below WACC destroys value through growth, even if earnings per share are rising.
Apple's ROIC of 45.1% compared to a WACC of approximately 10.5% creates a 34.6-point spread. Every dollar Apple reinvests at 45.1% generates returns far above the 10.5% rate at which the market discounts those returns back. That spread supports Apple's P/E of 28.3 in the DCF framework because the terminal growth assumption can carry real weight without requiring heroic reinvestment.
A business with ROIC of 10% and WACC of 9.5% has a 0.5-point spread. Growth in that business barely moves intrinsic value. The DCF model for that business should apply a low terminal growth rate and a conservative margin of safety.

Frequently Asked Questions
what is free cash flow
Free cash flow is the cash a business generates from operations after covering the capital expenditures needed to maintain and grow its productive assets. It is calculated as operating cash flow minus capital expenditures. Free cash flow cannot be as easily inflated by accounting choices as net income, which makes it the preferred input for discounted cash flow models. Apple generated approximately $108 billion in free cash flow in fiscal 2024, supporting buybacks and cash returns while maintaining its 45.1% ROIC.
what is the free cash flow
The free cash flow of a specific company in a specific period is its operating cash flow minus its capital expenditures, both taken directly from the statement of cash flows. For JNJ, this figure runs near $17 billion annually. For Microsoft, near $69 billion in FCFF terms. These figures are the direct inputs to a discounted cash flow model's projection stage and represent the clearest picture of what a business actually produces for its owners.
how to calculate free cash flow
To calculate free cash flow, pull operating cash flow from the operating section of the cash flow statement and subtract capital expenditures from the investing section. The formula is: Free Cash Flow = Operating Cash Flow - Capital Expenditures. For the FCFF variant, start from EBIT, multiply by (1 - tax rate), add D&A, subtract the change in net working capital, and subtract capex. Both approaches should produce similar results for most companies.
how to calculate intrinsic value using discounted cash flow
To calculate intrinsic value using a discounted cash flow model, project free cash flows for 5-10 years, discount each back to present value at WACC, add a terminal value calculated using the Gordon Growth Model (FCFn x (1+g) / (WACC - g)), sum the discounted cash flows and terminal value to get enterprise value, subtract net debt, and divide by diluted shares outstanding. Always run sensitivity analysis by varying the discount rate and terminal growth rate across a range of at least three scenarios.
a simplified common stock valuation model
The Gordon Growth Model is the standard simplified stock valuation approach for income-generating businesses: Value = D1 / (r - g). D1 is the next annual dividend, r is the required return, and g is the perpetual growth rate. It works best for mature dividend payers with consistent payout histories like JNJ (3.1% yield) and KO (3.0% yield, 60+ year payout streak). The model produces misleading results for non-dividend-paying companies or those in rapid growth phases where the dividend does not reflect free cash flow generation.
how to build a stock valuation model
To build a stock valuation model, select the method appropriate for the business: multi-stage DCF for companies with predictable free cash flows, EV/EBITDA relative valuation for cyclicals, or a dividend discount model for mature income payers. For a DCF model, gather 5+ years of free cash flow history, project forward using a two-stage growth model, build WACC from CAPM inputs plus the after-tax cost of debt, compute terminal value, and bridge to per-share equity value. Use the ValueMarkers screener to pull normalized financial data as your starting point, then build the model in the DCF calculator to generate sensitivity tables automatically.
