What is a DCF Model?

A DCF (Discounted Cash Flow) model is the gold standard for company valuation. It estimates a company's intrinsic value by projecting future free cash flows and discounting them to present value using the Weighted Average Cost of Capital (WACC).

Investment banks, private equity firms, and corporate finance teams use DCF models for:

  • M&A valuations and fairness opinions
  • Investment committee decisions
  • Pitch books and client presentations
  • Internal strategic planning

Traditional DCF modeling requires 4-8 hours of Excel work. With financial modeling AI like Shortcut, you can build complete DCF models in 5-10 minutes with 90%+ accuracy.

Components of a DCF Model

1. Revenue Projections

Project revenue 5-10 years based on:

  • Historical growth rates
  • Management guidance
  • Industry analysis and market size
  • Product pipeline and expansion plans

2. Operating Assumptions

Model EBITDA margins, CapEx, working capital:

  • EBITDA margin expansion or compression
  • D&A as % of revenue
  • CapEx requirements
  • Working capital changes (DSO, DPO, inventory turns)

3. WACC Calculation

Calculate the discount rate:

  • Cost of Equity: Risk-free rate + Beta × Equity risk premium
  • Cost of Debt: Interest rate × (1 - Tax rate)
  • Capital Structure: Weight debt and equity at market values

4. Free Cash Flow Build

Calculate FCF from EBITDA:

  • EBITDA
  • - Depreciation & Amortization
  • = EBIT
  • - Taxes
  • = NOPAT
  • + D&A
  • - CapEx
  • - Change in working capital
  • = Unlevered Free Cash Flow

5. Terminal Value

Estimate value beyond projection period:

  • Perpetuity Growth Method: FCF × (1 + g) / (WACC - g)
  • Exit Multiple Method: Final year EBITDA × Exit multiple

6. Present Value Calculation

Discount all cash flows and terminal value:

  • Sum of PV(FCF) for each projection year
  • + PV(Terminal Value)
  • = Enterprise Value
  • - Net Debt
  • = Equity Value
  • ÷ Shares outstanding = Price per share

7. Sensitivity Analysis

Test key assumptions:

  • WACC sensitivity (±200 bps)
  • Terminal growth sensitivity (±100 bps)
  • Revenue growth scenarios
  • EBITDA margin cases

Building DCF Models with AI

Traditional Manual Approach (4-8 hours)

  1. Download 10-K or financial statements (30 min)
  2. Build revenue model with drivers (1-2 hours)
  3. Model operating expenses and margins (1 hour)
  4. Calculate WACC components (30-45 min)
  5. Build FCF waterfall (45 min)
  6. Compute terminal value (15 min)
  7. Discount to present value (30 min)
  8. Create sensitivity tables (45 min)
  9. Format and validate (1 hour)

AI-Powered Approach (5-10 minutes)

Using Shortcut:

  1. Describe your DCF: "Build DCF for Apple using latest 10-K. 10-year projections, WACC 9%, terminal growth 2.5%, include sensitivity table."
  2. AI generates complete model: All components automated—revenue build, WACC, FCF, terminal value, PV calc, sensitivity
  3. Review and refine: "Adjust EBITDA margin expansion to 100 bps per year"
  4. Download .xlsx: Complete, formatted, ready for review

DCF Model Example: NVIDIA

AI Prompt

"Build 10-year DCF for NVIDIA using latest 10-K. Assume:

  • Revenue growth: 20% years 1-3, 15% years 4-5, 10% years 6-8, 5% terminal
  • EBITDA margin: 55% expanding to 60% by year 5
  • CapEx: 8% of revenue
  • Working capital: 10% of revenue change
  • WACC: 10%
  • Terminal growth: 3%

Include sensitivity table for WACC (8-12%) and terminal growth (2-4%). Format as professional pitch book."

AI Output (8 minutes)

  • Tab 1 - Assumptions: All key drivers clearly laid out
  • Tab 2 - Historical Financials: 3-5 years from 10-K
  • Tab 3 - Revenue Build: Segment breakdown with growth rates
  • Tab 4 - P&L Projections: Full 10-year income statement
  • Tab 5 - FCF Build: EBITDA to FCF waterfall
  • Tab 6 - WACC: Beta, risk-free rate, equity premium, debt cost
  • Tab 7 - DCF Valuation: PV of cash flows, terminal value, equity value
  • Tab 8 - Sensitivity: 2-way tables for WACC and terminal growth
  • Tab 9 - Executive Summary: Key metrics and valuation range

Best Practices for DCF Models

Revenue Modeling

  • Use bottom-up build when possible (units × price)
  • Consider product lifecycle stages
  • Model segment-level detail for diversified companies
  • Justify growth rate transitions with market analysis

WACC Calculation

  • Use market cap for equity weight, not book value
  • Calculate levered beta from peer group unlevered betas
  • Use current risk-free rate (10-year Treasury)
  • Apply standard 5-7% equity risk premium

Terminal Value

  • Terminal growth typically 2-3% (GDP growth proxy)
  • Perpetuity growth shouldn't exceed long-term GDP growth
  • Exit multiples should be comparable to current trading multiples
  • Terminal value usually 60-80% of total value

Sensitivity Analysis

  • Test WACC ±200 bps around base case
  • Test terminal growth ±100 bps
  • Show revenue and margin scenarios
  • Calculate implied multiples for sanity check

Common DCF Mistakes to Avoid

Circular References

Interest expense depends on debt, which depends on FCF, which depends on interest expense. Break circularity with iterative calculation or hard-code debt schedule.

Inconsistent Treatment

Don't mix levered and unlevered cash flows. DCF should use unlevered FCF (no interest expense) with WACC discount rate.

Unrealistic Margins

EBITDA margins shouldn't exceed industry leaders without strong justification. Use peer benchmarking.

Wrong Working Capital Treatment

Model change in working capital, not absolute level. Growing companies consume cash through WC investment.

DCF Model vs Trading Comps

DCF and comparable company analysis complement each other:

DCF ModelTrading Comps
Intrinsic value based on fundamentalsMarket-based relative valuation
Requires detailed projectionsUses current trading multiples
Sensitive to terminal valueReflects current market sentiment
Better for unique businessesBetter for mature, comparable cos

Best practice: Use both methods and triangulate to a valuation range.

  • Low CapEx, minimal working capital
  • Higher terminal multiples (20-30x EBITDA)

Industrial / Manufacturing

  • Moderate growth, stable margins
  • Significant CapEx for maintenance
  • Working capital tied to inventory cycles

Retail / Consumer

  • Revenue driven by store count × comp store growth
  • Inventory working capital requirements
  • Store build-out CapEx modeling

Financial Services

  • Use dividend discount model (DDM) instead of FCF
  • Model ROE and book value growth
  • Regulatory capital requirements
