The insight most investors miss
Every DCF is built on assumptions about growth rates, margins, and terminal values that no one can predict accurately 10 years out. The model will be wrong. That's not the point.
The value of DCF is that it makes your assumptions explicit and auditable. When you change your growth assumption from 12% to 8%, you see exactly how much you're overpaying for optimism. When you stress-test the discount rate, you find out how fragile your conviction is. No other valuation method forces this discipline — which is why analysts who skip DCF and jump straight to multiples tend to buy crowded trades at peak optimism.
DCF values a stock as the present value of all future free cash flows:
PV = FCF₁/(1+r)¹ + FCF₂/(1+r)² + … + TV/(1+r)ⁿ
Worked example: A company generating $500M FCF growing 8%/year for 5 years at a 10% WACC produces a terminal-inclusive intrinsic EV near $7.4B — divide by shares outstanding (minus net debt) to get per-share value.
Best for: Mature, FCF-positive businesses where you can model the next 5–10 years. Avoid for pre-revenue companies or highly lumpy FCF.
The three inputs that drive 90% of DCF output: near-term FCF growth rate, terminal growth rate (typically 2–4%), and discount rate (WACC, typically 8–12% for large-cap US equities). Run sensitivity tables before trusting any single output.
Run this method
Comps values a business by applying the multiples that the market currently pays for similar companies:
Enterprise Value = EBITDA × Industry Multiple
Worked example: If sector peers trade at 12× EV/EBITDA and your company has $200M EBITDA, implied EV = $2.4B. Subtract net debt and divide by shares for equity value per share.
Best for: Companies with liquid public peers and stable sector multiples. Fast and grounded in market reality — but dangerous in isolation. A comps-only analysis tells you whether a stock is cheap relative to peers, not whether the whole sector is mispriced.
Use comps to calibrate and sanity-check your DCF output, not replace it.
Run this method
Precedent transactions look at the multiples paid in recent acquisitions of comparable companies — typically 20–40% above public comps due to the control premium.
Worked example: If recent acquisitions in the sector were done at 15× EV/EBITDA (versus public comps at 12×), that 3-turn premium reflects what a strategic buyer paid for control. Applied to your company's $200M EBITDA, transaction value = $3.0B vs. the public-market comps value of $2.4B.
Best for: M&A context — assessing take-private value, evaluating a strategic bid, or stress-testing whether a stock is cheap enough to attract a buyer. Not useful for minority-position equity analysis because public minority investors do not receive the control premium.
Use the Comps tool to benchmark current public multiples as a baseline, then apply a transaction premium from recent deal data in the sector.
Run the baseline analysis
SOTP values each business segment or asset class separately, then sums them and subtracts net debt:
Equity Value = Σ(Segment EV) − Net Debt
Worked example: A conglomerate with Division A (industrial) valued at 8× EBITDA on $200M = $1.6B, plus Division B (software) valued at 15× EBITDA on $50M = $750M, minus $400M net debt → equity value = $1.95B. A single-multiple comps analysis would apply one average multiple, burying the software premium in the blended rate.
Best for: Conglomerates, holding companies, and asset-heavy businesses (real estate, mining, energy) where operating cash flow is secondary to balance sheet composition. Also valuable when a company is considering a spin-off — SOTP shows whether the sum is worth more than the whole.

A DCF has many inputs but three dominate the output:
Run sensitivity tables on these three inputs before trusting any DCF output. If your investment thesis only works at a 7% discount rate and 5% terminal growth, you should know that before buying.

By the numbers
S&P 500 historical median P/E: 15–18x. Above 22x typically means the market is pricing in strong earnings growth or very low interest rates. Below 12x historically signals recession fear or credit stress.
WACC range for US large-caps: 8–10% (cost of equity 9–12%, weighted by balance sheet mix). Growth companies warrant 12–15%; defensive utilities trade on 6–8%.
Terminal growth rate convention: 2–3% for stable businesses; up to 4% for secular-growth companies. Anything above 4% implies the company eventually grows larger than the US economy — almost always an error.
Margin of safety convention: 20–35% below intrinsic value for a quality business; 40–50% for a lower-quality or cyclical one. The required margin grows with your uncertainty about the inputs.

Common questions
What is a DCF model?
A discounted cash flow (DCF) model values a stock as the present value of all future free cash flows the business is expected to generate. You forecast 5–10 years of free cash flow, apply a terminal value for the years beyond, and discount everything back to today using a rate that reflects the risk of those cash flows. The output is intrinsic value per share — what the business is theoretically worth.
How do you calculate intrinsic value?
Intrinsic value is calculated by projecting a company's future free cash flows, discounting them to present value at an appropriate cost of capital, adding a terminal value for the perpetuity period, and dividing the total enterprise value (minus net debt) by shares outstanding. The result is per-share intrinsic value. Compare it to the current market price to see whether the stock is trading at a discount or premium.
What discount rate should I use for a DCF?
Most analysts use the weighted average cost of capital (WACC), which blends cost of equity and after-tax cost of debt by their respective weights in the capital structure. For large-cap US equities, 8–10% is typical; higher-risk growth companies warrant 12–15%. Run sensitivity tables at multiple rates rather than committing to one number — our DCF Calculator lets you stress-test discount rates instantly.
DCF vs comparable analysis — which is better?
Neither alone is sufficient. DCF is theoretically rigorous but highly sensitive to assumptions about growth, margins, and discount rates. Comparable (multiples) analysis is fast and grounded in market reality but tells you nothing if the entire peer group is mispriced. Experienced investors triangulate both — DCF for absolute value, comparables for sanity-checking the result against how the market is currently pricing similar businesses.
How do you value a stock with no earnings?
When a company has no earnings, traditional P/E analysis breaks down. Analysts typically use revenue-based multiples (EV/Revenue), a DCF built on projected future free cash flows once the business reaches profitability, or comparable transaction values from recent M&A in the sector. The key is estimating when and at what margin the company will generate positive cash flow, then discounting that back to today.
