How to Calculate Intrinsic Value of a Stock: Complete DCF Guide 2026

Here's the truth about stock prices: they have nothing to do with what companies are actually worth. The market runs on emotions, hype, and quarterly drama. But underneath all that noise, every business has an intrinsic value based on cold, hard cash flows.

I'll walk you through exactly how to calculate what a stock is really worth using Microsoft as a real example with actual numbers. By the end, you'll know whether you're getting a bargain or paying bubble prices.

What Is Intrinsic Value (Without the MBA Jargon)?

Think of intrinsic value as the price tag a business would have if emotions, hype, and market manipulation disappeared overnight. It's what the company is worth based purely on how much cash it can generate for owners over time.

The basic idea: A business is worth the total cash it will produce in the future, adjusted for the fact that future money is worth less than money today.

Why this matters: If you can buy a $100 bill for $70, you make money. If intrinsic value is $150 per share and the stock trades at $120, you've found a bargain. If intrinsic value is $80 and the stock trades at $120, you'll lose money.

The Only Valuation Method That Actually Matters: DCF

Forget P/E ratios and price-to-sales comparisons. Those are just guessing based on what other people paid. Discounted Cash Flow (DCF) analysis tells you what the business is actually worth.

The DCF concept in plain English: 1. Estimate how much free cash the company will generate each year 2. Add up all that future cash
3. Discount it back to today's value (because $1 next year is worth less than $1 today) 4. That's your intrinsic value

Let me show you exactly how this works with Microsoft.

Real DCF Example: Microsoft (MSFT)

Let's value Microsoft step-by-step using real numbers from our screener: - Current metrics: 37% ROE, 32% ROIC, 9/10 moat score - Strong competitive moats: Office ecosystem lock-in, Azure cloud growth, enterprise relationships

Step 1: Find Microsoft's Current Free Cash Flow

Free Cash Flow = Operating Cash Flow minus Capital Expenditures

Microsoft's 2025 numbers: - Operating Cash Flow: $88.5 billion - Capital Expenditures: $28.1 billion
- Free Cash Flow: $60.4 billion

This is the cash Microsoft generated that could be paid to shareholders after maintaining and growing the business.

Step 2: Project Future Cash Flows

Here's where art meets science. We need to estimate how Microsoft's cash flows will grow over the next 10 years.

Growth drivers to consider: - Azure cloud growth (25%+ annually) - Office 365 expansion (steady mid-single digits) - Gaming and LinkedIn growth - AI integration across all products

My projections for Microsoft: - 2026: $66.4 billion (10% growth) - 2027: $72.4 billion (9% growth)
- 2028: $78.2 billion (8% growth) - 2029: $83.4 billion (7% growth) - 2030: $87.9 billion (5% growth) - Years 6-10: Gradual decline to 3% long-term growth

Reality check: I'm assuming Microsoft grows faster than GDP but slower than it has historically. This balances optimism with realism.

Step 3: Calculate the Discount Rate

This is where most people get lost in finance theory. Here's the simple version:

What discount rate should you use? - Conservative approach: 10-12% for large, stable companies - For Microsoft specifically: 10.5% (reflects low risk from strong moats)

Why discount future cash? Money today is worth more than money tomorrow because: 1. You could invest it and earn returns 2. There's always risk the future cash won't materialize 3. Inflation reduces purchasing power over time

Step 4: Calculate Present Values

Now we discount each year's projected cash flow back to today's dollars:

The math: - 2026: $66.4B ÷ (1.105)¹ = $60.1B - 2027: $72.4B ÷ (1.105)² = $59.3B
- 2028: $78.2B ÷ (1.105)³ = $58.0B - 2029: $83.4B ÷ (1.105)⁴ = $56.2B - 2030: $87.9B ÷ (1.105)⁵ = $54.2B

Total present value of 5-year cash flows: $287.8 billion

Step 5: Calculate Terminal Value

Here's the tricky part: what happens after year 5? Microsoft doesn't disappear. It keeps generating cash flows forever.

Terminal value formula: Terminal Value = Final Year Cash Flow × (1 + Long-term Growth) ÷ (Discount Rate - Long-term Growth)

For Microsoft: - Final year cash flow: $87.9 billion - Long-term growth: 3% (roughly matches economic growth) - Terminal Value = $87.9B × 1.03 ÷ (10.5% - 3%) = $1,207 billion

Present value of terminal value: $1,207B ÷ (1.105)⁵ = $744 billion

Step 6: Add It All Up

Enterprise Value = Present Value of Cash Flows + Present Value of Terminal Value Enterprise Value = $287.8B + $744B = $1,032 billion

But wait! Enterprise value includes debt holders. We want equity value.

Equity Value = Enterprise Value + Cash - Debt - Microsoft's cash: $75.2 billion - Microsoft's debt: $41.5 billion
- Equity Value = $1,032B + $75.2B - $41.5B = $1,066 billion

Step 7: Calculate Per-Share Value

  • Microsoft shares outstanding: 7.43 billion
  • Intrinsic value per share = $1,066B ÷ 7.43B = $143

Step 8: Compare to Market Price

If Microsoft trades at $420 per share (current price as I write this): - Market price: $420 - Intrinsic value: $143 - Microsoft is overvalued by 194%

Translation: The market is pricing in expectations that Microsoft will grow much faster than I projected, or it's in bubble territory.

The Margin of Safety: Your Insurance Policy

Even if your DCF is perfect (it won't be), always buy with a margin of safety. This protects you against: - Overly optimistic projections - Business deterioration
- Market volatility - Black swan events

Conservative approach: Only buy when the stock trades at least 25% below intrinsic value.

For Microsoft example: - Intrinsic value: $143 - Buy price with 25% margin of safety: $107 - Current market price: $420 - Verdict: Wait for a massive crash or skip this stock

Quick Valuation Methods When DCF Feels Like Overkill

Sometimes you need a quick sanity check without building a full model:

The Earnings Method

Rule of thumb: A stock is reasonably valued if PE ratio equals expected growth rate.

Microsoft example: - 2026 estimated earnings per share: $13.20 - Current stock price: $420
- PE ratio: 420 ÷ $13.20 = 31.8x - Expected earnings growth: ~8% annually - Verdict: PE of 32x for 8% growth suggests overvaluation

The Free Cash Flow Yield Method

Simple check: What percentage return are you getting on free cash flow?

Microsoft calculation: - Free cash flow per share: $60.4B ÷ 7.43B shares = $8.13 - Current stock price: $420 - Free cash flow yield: $8.13 ÷ $420 = 1.9% - Problem: You're getting a 1.9% cash return on a $420 investment. That's terrible.

The Revenue Multiple Check

For growth stocks: Compare price-to-sales ratio to growth rate and margins.

Microsoft numbers: - Revenue per share: ~$40 - Current price: $420
- Price-to-sales: 10.5x - Rule of thumb: P/S above 8x requires exceptional growth to justify

Common Valuation Mistakes (Learn from My Failures)

Mistake #1: Garbage In, Garbage Out Projections

What I used to do: Project 15% growth forever because the company had grown 15% historically. Reality: All growth slows down. Competitors catch up. Markets saturate. Fix: Be conservative. Model competitive pressure. Include recession scenarios.

Mistake #2: Ignoring the Terminal Value

The problem: 70%+ of DCF value often comes from terminal value (cash flows after year 10). Why this matters: Small changes in terminal growth assumptions drastically change intrinsic value. Solution: Keep terminal growth rates below 4%. Use multiple scenarios.

Mistake #3: Using the Wrong Discount Rate

Common error: Using 8% because "that's what the stock market returns." Better approach: Higher discount rate for riskier companies, lower for stable moats. For beginners: Use 10% for all companies until you get comfortable with adjustments.

Mistake #4: Falling in Love with Your Analysis

The trap: Spending hours on a model makes you emotionally invested in buying the stock. Reality check: If your DCF says "buy" but everything else screams "overvalued," trust the other signals. Solution: Do multiple valuation methods. Get outside opinions.

When DCF Doesn't Work

Avoid DCF for: - Startups with no cash flows: Use revenue multiples or option value models instead - Cyclical businesses: Normalize earnings over full cycles first
- Financial companies: Use price-to-book and return on equity models - Asset-heavy businesses: Sometimes liquidation value matters more than cash flows

Stick with DCF for: - Mature companies with predictable cash flows - Businesses with strong competitive moats - Companies you understand well - Long-term investment decisions

Building Your Valuation Toolkit

Start with These 3 Methods

  1. Quick PE check: Is the PE ratio reasonable for the growth rate?
  2. Free cash flow yield: Are you getting decent cash returns?
  3. Simple DCF: Use conservative assumptions and see what you get

Excel Tips for DCF Models

Keep it simple: - One tab for assumptions - One tab for projections
- One tab for valuation calculations - Build in sensitivity analysis (what if growth is 2% higher/lower?)

Don't overcomplicate: - Start with 5-year projections - Use round numbers for growth rates - Focus on big assumptions, not decimal places

Red Flags That Override DCF Analysis

Even if your DCF says "buy," avoid stocks with: - Deteriorating competitive positions - Management with poor capital allocation history
- High customer concentration risk - Regulatory threats to the business model - Declining profit margins over multiple years

The Moat Connection: Why DCF Works Better with Strong Businesses

Companies with economic moats make DCF analysis more reliable because:

Predictable cash flows: Strong moats create consistent, growing cash generation Lower risk: Competitive protection reduces business risk and justifies lower discount rates
Terminal value confidence: Wide-moat businesses are more likely to survive and thrive long-term

Examples from our screener: - NVIDIA (9/10 moat, 49% ROE): CUDA ecosystem creates predictable AI infrastructure demand - Microsoft (9/10 moat, 37% ROE): Office lock-in generates recurring enterprise cash flows - Apple (9/10 moat, 164% ROE): Device ecosystem creates predictable upgrade cycles

The Bottom Line

Intrinsic value calculation isn't about precision. It's about being roughly right instead of precisely wrong. Your goal is to distinguish between obvious bargains and obvious overvaluations.

Key principles: - Conservative assumptions beat optimistic ones - Multiple methods provide better insights than perfect models
- Margin of safety protects against errors - Strong businesses make valuations more reliable

Most importantly, remember that DCF is a tool, not a crystal ball. It helps you make better investment decisions by focusing on business fundamentals rather than market emotions.

Start simple, practice with companies you understand, and gradually build sophistication. The goal isn't to become a Wall Street analyst. It's to avoid paying $420 for something worth $143.
