When it comes to calculating the intrinsic value of a stock, Discounted Cash Flow (DCF) analysis stands out as one of the most reliable methods. Although it requires more effort and financial insight than using quick financial ratios, DCF gives you a clearer, more accurate picture of a stock’s true worth.
In this blog, we’ll dive deep into the DCF method—what it is, how it works, and how you can use it to value stocks effectively.
???? Why Calculate Intrinsic Value?
Intrinsic value is the real worth of a company based on its fundamentals—not its current stock price.
By comparing the intrinsic value with the market price, investors can decide whether a stock is:
- Undervalued (good to buy),
- Fairly priced, or
- Overvalued (better to avoid or sell).
Why Not Just Use Financial Ratios?
Financial ratios are commonly used because they are:
- Quick to calculate
- Easy to understand
These include metrics like:
- Price to Earnings (P/E)
- Price to Book (P/B)
- Price to Sales (P/S)
- Dividend Yield
- Free Cash Flow Yield
While useful, ratios provide only a crude approximation of value. They lack the depth and forward-looking perspective that DCF offers.
What is Discounted Cash Flow (DCF)?
The DCF model values a company based on the present value of all expected future cash flows.
In simple terms:
Intrinsic Value = Present Value (PV) of all future Free Cash Flows (FCFs)
DCF Flow Chart:
- Forecast future free cash flows (typically for 5–10 years)
- Estimate a discount rate
- Calculate the present value of each cash flow
- Add a terminal value to account for all cash flows beyond the forecast period
- Sum it all up → Intrinsic value of the company
- Divide by number of shares → Intrinsic value per share
DCF Explained with an Example
Let’s simplify it with a hypothetical company, ABCD:
Assume ABCD will generate the following FCFs over six years:
| Year | Cash Flow (in ₹ Crores) |
| 1 | 100 |
| 2 | 110 |
| 3 | 121 |
| 4 | 133 |
| 5 | 146 |
| 6 | 450 |
If the discount rate is 9%, the intrinsic value is calculated by discounting each cash flow:
Intrinsic Value = 100/(1+0.09)^1 +
110/(1+0.09)^2 +
121/(1+0.09)^3 +
133/(1+0.09)^4 +
146/(1+0.09)^5 +
450/(1+0.09)^6
= ₹735.2 Crores
Estimating Future Free Cash Flow (FCF)
What is Free Cash Flow?
FCF = Net Cash from Operations – Capital Expenditures
You can also estimate it using:
FCF = Net Profit + Depreciation & Amortization – Change in Working Capital – CAPEX
To project future FCFs:
- Analyze past 5 years’ FCF trend
- Consider industry dynamics:
- Sector competitiveness
- Company’s economic moat
- Sector competitiveness
Strong past performance and a solid moat often indicate steady future growth.
Why Use a Discount Rate?
Future money is worth less than today’s due to inflation and opportunity cost.
The discount rate helps convert future cash into present value.
Two common methods:
- Inflation-based (e.g., 7% inflation rate)
- Expected return-based (e.g., 15% personal investment benchmark)
However, analysts usually prefer the Weighted Average Cost of Capital (WACC) for more realistic projections.
Terminal Value (TV): Estimating Infinite Cash Flows
It’s nearly impossible to predict FCFs forever. Instead, we estimate a Terminal Value (TV) after the projection period (say 5 years).
TV Formula:
TV = Final Year FCF × (1 + g) / (r – g)
Where:
- g = perpetual growth rate (usually 4–5%)
- r = discount rate
Total Intrinsic Value:
DCF Value = PV of 5-year FCFs + PV of Terminal Value
Complete Example: Intrinsic Value Using DCF
Assumptions:
- FCFs for 5 years: ₹100, ₹110, ₹121, ₹133, ₹146 Crores
- Discount Rate (r) = 9%
- Perpetual Growth Rate (g) = 5%
- Shares Outstanding = 100 Crore
Using the DCF model:
- Terminal Value (Year 5) =
₹146 × (1+5%) / (9%-5%) = ₹3,832.5 Crores - Total PV of all FCFs + TV =
₹4,299.4 Crores - Intrinsic Value per Share =
₹4,299.4 / 100 = ₹42.99
If the stock is currently trading at ₹60, it is overvalued.
DCF: Limitations & Considerations
- Estimating future FCFs is not easy
- Picking the right discount rate is crucial
- Terminal value often contributes 80-90% of the total valuation
- Requires a deep understanding of the company’s financials
Conclusion: Is DCF Worth It?
Yes, absolutely. Although DCF is more complex than financial ratios, it is one of the most robust methods to determine intrinsic value.
It’s ideal for long-term, value-focused investors who want a data-driven way to make investment decisions. Just remember: the accuracy of your inputs will define the accuracy of your valuation.
