DCF Valuation — Cash Flow to Intrinsic Value

Learning Objectives

After reading this chapter, you will be able to:

• Explain how DCF is the foundation of professional valuation — converting future cash flows to today's price; useful only with conservative inputs and margin of safety; remember garbage in, garbage out
• Apply DCF Valuation metrics and formulas using consolidated NSE/BSE annual report data
• Identify red flags when interpreting DCF Valuation: unrealistic 20%+ perpetual growth
• Connect DCF Valuation analysis to peer comparison and buy/hold/avoid decisions

Introduction

So far we have learned: EPS, book value, Graham Number, intrinsic value, margin of safety. But one question remains:

"If I wanted to buy the entire business, how would I calculate its true price?"

This is where Discounted Cash Flow (DCF) valuation begins — the most powerful framework in modern valuation. Professional investors, investment bankers, private equity funds, and equity research analysts use DCF.

Core Concepts

Financial Terms

Investment Decision

Golden Rule: DCF is the art of converting future cash generation into today's price.

Novice investor: What is the P/E? Experienced investor: What is the Graham Number? Professional analyst: "How much cash will this business generate in the future?"

Buffett think about price differently: "How much cash will this business generate over the next 10–20 years?" — this is the DCF mindset.

"The market sets the share price, but future cash flow sets its value."

The value of a business is the present value of its future cash flows.

Note: DCF looks at cash flow, not profit. Ultimately the shareholder receives cash, not accounting profit.

"A DCF output is only as good as its input."

1. Future Cash Flow — why FCF? Profit ₹100 Cr, Capex ₹90 Cr → actual cash ₹10 Cr
2. Growth Rate — the most dangerous input; 10% vs 25% growth = very different value
3. Discount Rate — in India typically 10%–15%

Most businesses do not shut down after 5 years — they keep generating cash. Terminal Value is added.

Professional Reality: In many DCF models, 60–80% of valuation comes from terminal value — terminal assumptions are extremely important.

Simplified DCF Example

DCF is not an exact science — it is educated estimation. Change growth or discount rate and valuation changes. Wrong assumptions = wrong DCF.

Many think Buffett does not use DCF. In fact his entire thinking is DCF-based:

"How much cash will this business generate over the next 10–20 years?"

DCF never gives an exact value. If DCF value is ₹1000, buying at ₹1000 is not mandatory — ₹700–800 may be safer.

Formula & Explanation

Basic Present Value

Where: CF = Future Cash Flow, r = Discount Rate, n = Years

Example: ₹100 in 5 years, Discount Rate 10%

The value today of ₹100 received in 5 years is roughly ₹62.

Business Valuation

Discount each year's cash flow to present value and sum = business value.

Equity Value

Worked Example — Indian Market

DCF Sanity Check

If DCF equity value ₹500 Cr but market cap ₹1,200 Cr → market pricing aggressive growth. Sensitivity: ±1% WACC or terminal growth changes IV sharply.

Real World Example

I offer you two choices:

Most people choose ₹100 today — because today's money is worth more than future money. This is Time Value of Money — the foundation of DCF.

Case Study

TCS, BEL, PFC, Maithan Alloys, Gravita:

• TCS: Stable FCF, 10–12% discount rate, Terminal Value dominant
• BEL: Defence order book visibility — growth assumptions conservative
• PFC/REC: Cyclical lending — DCF less reliable; asset-based cross-check
• Maithan Alloys: Commodity normalisation critical for FCF forecast
• Gravita: Growth capex heavy — FCF vs reported profit gap important

Disclaimer: DCF models are highly sensitive to assumptions; sensitivity analysis recommended.

CFA Exam Tip

Before building a DCF, I ask:

1. Is the business predictable?
2. Is cash flow stable?
3. Is growth sustainable?
4. How much debt is there?
5. Is management trustworthy?

Common Mistakes

1. Assuming growth too high
2. Using discount rate too low
3. Ignoring debt
4. Overestimating terminal value
5. Treating DCF as absolute truth

Common Mistakes

• Unrealistic 20%+ perpetual growth
• Discount rate below risk-free rate
• Terminal Value > 80% of total value
• Negative FCF ignored in projections
• No sensitivity analysis on key inputs

Key Takeaways

DCF is the foundation of professional valuation — converting future cash flows to today's price. It is useful only with conservative inputs and margin of safety. Garbage in, garbage out — always remember that.

FAQ {#faq}

Q: What should I check alongside DCF Valuation screening?

A: Debt, FCF trend, and business predictability — DCF alone does not confirm value.

Q: How do I connect theory to Indian market practice?

A: Use Screener/Trendlyne + company annual reports — plot the same metrics over 3 years; paper formulas alone are insufficient.

Q: Why avoid unrealistic 20%+ perpetual growth?

A: Terminal value dominates most DCF models — aggressive growth assumptions destroy reliability.

Q: Why is a discount rate below the risk-free rate a red flag?

A: It understates risk and overstates present value.

Q: How do I drill these concepts in the Practice Lab?
