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

- AI generates complete model: All components automated—revenue build, WACC, FCF, terminal value, PV calc, sensitivity
- Review and refine: "Adjust EBITDA margin expansion to 100 bps per year"
- 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."

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 Model | Trading Comps |
---|---|
Intrinsic value based on fundamentals | Market-based relative valuation |
Requires detailed projections | Uses current trading multiples |
Sensitive to terminal value | Reflects current market sentiment |
Better for unique businesses | Better for mature, comparable cos |
Best practice: Use both methods and triangulate to a valuation range.

- Working capital tied to inventory cycles
Retail / Consumer
- Revenue driven by store count × comp store growth
- Inventory working capital requirements
