Estimate the intrinsic value of an investment or a company based on its expected future cash flows. DCF analysis helps you determine if an asset is undervalued or overvalued in the current market.
DCF Parameters
Enter the parameters to calculate the Discounted Cash Flow value
Formula Used (DCF)
DCF = Σ [CFt / (1 + r)^t] + [TV / (1 + r)^n]
TV (Perpetuity) = [CFn * (1 + g)] / (r - g)
CFt = Cash Flow in Year t
r = Discount Rate (WACC)
TV = Terminal Value
n = Total Number of Years

The Discounted Cash Flow (DCF) method is an analytical valuation technique based on the principle that the value of an asset (in this case, a company) is the sum of the present value of its expected future cash flows.
Intrinsic Value vs. Market Value
DCF aims to calculate the **Intrinsic Value** of a company—the actual value derived from its business operations and future cash-generating capacity. This value is then compared to the current **Market Value** (market capitalization). The premise is that if the Intrinsic Value is significantly higher than the Market Value, the stock is undervalued.
Terminal Value (TV): Estimating the value of all cash flows beyond the forecast period.
Discounting: Bringing all future cash flows (steps 1 and 2) back to the Present Value using the Discount Rate (WACC).
Step 1: Forecasting Free Cash Flow (FCF)
The most critical input in a DCF model is the **Free Cash Flow (FCF)**, which represents the cash a company generates after accounting for all operating expenses and capital expenditures (CapEx). It is the true cash available to the company’s investors (debt and equity holders).
FCF to Firm (FCFF) vs. FCF to Equity (FCFE)
Most enterprise valuations use **FCF to Firm (FCFF)** because it represents the cash flow generated *before* any payments are made to providers of capital (both debt and equity). It is the standard input for an Enterprise Value calculation.
Where EBIT is Earnings Before Interest and Taxes, T is the Tax Rate, D&A is Depreciation and Amortization, CapEx is Capital Expenditures, and NWC is Net Working Capital.
Step 2: The Core DCF Formula and Discounting
The core of the DCF process is discounting the projected Free Cash Flows (FCF) back to the present using the appropriate discount rate (r).
Discounting the Explicit Forecast Period
The Present Value (PV) of the explicit forecast period is the sum of the PV of each year's expected cash flow:
PV_{Forecast} = Sum [ FCF_t / (1 + r)^t ]
Where r is the discount rate (WACC for FCFF) and t is the year of the cash flow. This step converts the projected income into a current, comparable dollar value.
Step 3: Calculating Terminal Value (TV)
The **Terminal Value (TV)** is the present value of all cash flows a company is expected to generate *after* the explicit forecast period has ended. It often accounts for 60% to 80% of the total Enterprise Value, making its calculation highly sensitive.
Method 1: The Perpetuity (Gordon Growth) Model
The preferred method assumes the company will grow at a constant, sustainable rate (g) forever. This growth rate (g) must be less than the discount rate (r).
TV_n = FCF_{n+1} / (r - g)
Where the Terminal Value (TV) is the value at the end of the last forecast year, Cash flow in the first year of the perpetuity and WACC are used in the formula.
Method 2: The Exit Multiple Method
This method estimates the TV based on the average valuation multiples (e.g., Enterprise Value/EBITDA) of comparable publicly traded companies. While simpler, it is less theoretically rigorous as it relies on current market sentiment:
TV_n = EBITDA_n * Exit Multiple
Final DCF Equation
The two parts are then summed and added to the Present Value of any non-operating assets (e.g., cash) to determine the total Enterprise Value (EV):
Enterprise Value = PV_{Forecast} + PV_{Terminal Value}
The Discount Rate: Weighted Average Cost of Capital (WACC)
The appropriate discount rate for discounting FCFF is the **Weighted Average Cost of Capital (WACC)**. WACC represents the blended cost of a company's financing sources (debt and equity), adjusted for the tax-deductibility of interest expense.
WACC Formula
WACC serves as the minimum rate of return a project must achieve to satisfy both its creditors and shareholders:
WACC = (E/V) * Re + (D/V) * Rd * (1 - T)
Where Re (Cost of Equity) is calculated using the **Capital Asset Pricing Model (CAPM)**, and Rd is the Cost of Debt.
Calculating Equity Value
The final step in a DCF valuation is converting the calculated **Enterprise Value (EV)** to **Equity Value** (or Market Capitalization):
Equity Value = Enterprise Value + Cash - Debt
Dividing the Equity Value by the number of outstanding shares yields the theoretical Intrinsic Value Per Share.
Conclusion
The Discounted Cash Flow (DCF) model is the most comprehensive method for determining a company’s **Intrinsic Value**. Its precision relies on the rigor of its inputs, particularly the accurate forecasting of Free Cash Flow, the appropriate calculation of the WACC as the discount rate, and the justifiable estimation of the Terminal Value.
While subjective inputs make DCF sensitive, it remains the superior framework for investment decision-making because it links a company's current valuation directly to the future cash it is expected to generate for its owners.
Frequently Asked Questions
Common questions about Discounted Cash Flow analysis and valuation
What is Discounted Cash Flow (DCF)?
DCF is a valuation method that estimates the intrinsic value of an investment by discounting its projected future cash flows to present value using a required rate of return.
How is DCF different from NPV?
DCF calculates the total present value of future cash flows, while NPV subtracts the initial investment from DCF. DCF gives you the intrinsic value, NPV tells you the net benefit.
What is terminal value and why is it important?
Terminal value represents the present value of all future cash flows beyond the projection period. It's often a significant portion of DCF and requires careful estimation of long-term growth rates.
How do I choose the right discount rate for DCF?
Use the company's weighted average cost of capital (WACC), or for equity-focused analysis, use the cost of equity derived from CAPM. The rate should reflect the risk of the investment.
What are the main limitations of DCF analysis?
DCF relies heavily on assumptions about future cash flows, growth rates, and discount rates. Small changes in these assumptions can significantly impact the valuation. It also doesn't account for market sentiment or qualitative factors.
How many years should I project cash flows?
Typically 5-10 years for detailed projections, followed by a terminal value. The exact period depends on the business cycle, industry stability, and your confidence in long-term forecasts.
When should I use DCF vs. other valuation methods?
Use DCF for companies with predictable cash flows and when you want to understand intrinsic value. For companies with uncertain cash flows, consider using relative valuation methods like P/E ratios or comparable company analysis.
How do I handle high-growth companies in DCF?
For high-growth companies, use multi-stage DCF models with different growth phases. Start with high growth, transition to moderate growth, and end with stable growth for terminal value calculation.
What's a reasonable terminal growth rate?
Terminal growth rates typically range from 2-4%, often matching long-term GDP growth or inflation. Avoid rates higher than the discount rate, as this creates unrealistic valuations.
How do I validate my DCF assumptions?
Perform sensitivity analysis by varying key assumptions, compare with market valuations and peer companies, and ensure your assumptions are consistent with industry trends and company fundamentals.
