The diagram above shows the corporate finance decision-making framework we’ll master.

📖 Section 1: Time Value of Money - The Foundation

The most fundamental concept in finance: A dollar today is worth more than a dollar tomorrow.

Why Time Value of Money Matters

Money has time value for three reasons:

Opportunity cost - Money today can be invested to earn returns
Inflation - Money loses purchasing power over time
Risk - Future payments are uncertain

Understanding time value of money is essential for every financial decision: investments, loans, retirement planning, business valuation, and more.

Future Value (FV): Growing Money Over Time

Future Value answers: “If I invest money today, how much will I have in the future?”

Formula:

FV = PV \times (1 + r)^n

Where:

$FV$ = Future Value
$PV$ = Present Value (amount invested today)
$r$ = Interest rate per period (as decimal)
$n$ = Number of periods

Example 1: You invest $1,000 today at 8% annual interest for 5 years.

\begin{aligned} FV &= \$1,000 \times (1 + 0.08)^5 \\ FV &= \$1,000 \times (1.08)^5 \\ FV &= \$1,000 \times 1.4693 \\ FV &= \$1,469.30 \end{aligned}

Your $1,000 grows to$ 1,469.30 in 5 years.

Example 2: CloudTech invests $100,000 at 10% for 3 years.

\begin{aligned} FV &= \$100,000 \times (1.10)^3 \\ FV &= \$100,000 \times 1.331 \\ FV &= \$133,100 \end{aligned}

Present Value (PV): Today’s Worth of Future Money

Present Value answers: “What is future money worth today?”

This is the most important concept in corporate finance—it lets you compare future cash flows in today’s dollars.

Formula:

PV = \frac{FV}{(1 + r)^n}

Or equivalently:

PV = FV \times (1 + r)^{-n}

Example 1: You’ll receive $10,000 in 5 years. With a 6% discount rate, what’s it worth today?

\begin{aligned} PV &= \frac{\$10,000}{(1.06)^5} \\ PV &= \frac{\$10,000}{1.3382} \\ PV &= \$7,472.58 \end{aligned}

$10,000 received in 5 years is worth$ 7,472.58 today.

Example 2: CloudTech expects to receive $50,000 in 2 years. At 12% discount rate:

\begin{aligned} PV &= \frac{\$50,000}{(1.12)^2} \\ PV &= \frac{\$50,000}{1.2544} \\ PV &= \$39,860.14 \end{aligned}

	style PV2 fill:#0173B2,stroke:#000000,color:#FFFFFF

Discount Rate: The Key Number

The discount rate (r) represents:

Opportunity cost - Return you could earn on alternative investments
Required return - Minimum acceptable return for the risk level
Cost of capital - What it costs the company to raise funds

Choosing the right discount rate is critical - too low and you accept bad projects; too high and you reject good ones.

Risk and Required Return

Different investments require different discount rates based on risk:

  flowchart TD
	A[Investment Risk Categories] --> B[Low Risk<br/>Discount Rate: 4-6%]
	A --> C[Medium Risk<br/>Discount Rate: 8-12%]
	A --> D[High Risk<br/>Discount Rate: 15-25%]

	B --> B1[Examples:<br/>• Government bonds<br/>• Stable utilities<br/>• Blue-chip stocks]
	C --> C1[Examples:<br/>• Established companies<br/>• Real estate<br/>• Corporate bonds]
	D --> D1[Examples:<br/>• Startups<br/>• Emerging markets<br/>• Speculative ventures]

	style C fill:#DE8F05,stroke:#000000,color:#FFFFFF
	style D fill:#DE8F05,stroke:#000000,color:#FFFFFF

Rule: Higher risk = Higher required return = Higher discount rate

⚠️ Common Mistake: Confusing interest rate with discount rate.

Interest rate = Rate at which money grows (future value)
Discount rate = Rate at which you bring future money to present (present value)

They use the same formula but opposite directions: growing vs. discounting.

Annuities: Series of Equal Payments

An annuity is a series of equal payments at regular intervals.

Present Value of Annuity:

PV = PMT \times \frac{1 - (1 + r)^{-n}}{r}

Where:

$PMT$ = Payment amount each period
$r$ = Discount rate per period
$n$ = Number of periods

Example: CloudTech will receive $20,000 per year for 5 years. At 10% discount rate, what’s the PV?

\begin{aligned} PV &= \$20,000 \times \frac{1 - (1.10)^{-5}}{0.10} \\ PV &= \$20,000 \times \frac{1 - 0.6209}{0.10} \\ PV &= \$20,000 \times \frac{0.3791}{0.10} \\ PV &= \$20,000 \times 3.791 \\ PV &= \$75,820 \end{aligned}

The stream of $20,000 payments is worth$ 75,820 today.

✓ Checkpoint

What you’ve learned:

Time value of money: a dollar today > dollar tomorrow
Future value: growing money over time (1 + r)^n
Present value: today’s worth of future money (discounting)
Discount rate represents opportunity cost and required return
Annuities: valuing streams of equal payments

Practice: If you’ll receive $5,000 in 3 years and the discount rate is 8%, what’s the present value?

Solution

\begin{aligned} PV &= \frac{\$5,000}{(1.08)^3} \\ PV &= \frac{\$5,000}{1.2597} \\ PV &= \$3,969.16 \end{aligned}

The $5,000 future payment is worth$ 3,969.16 today.

📖 Section 2: Financial Statement Analysis - Reading the Numbers

Before making financial decisions, you need to understand a company’s current financial position.

The Three Financial Statements (Quick Review)

Income Statement - Shows what happened: Revenue minus all expenses to get Net Income (profit or loss)

Balance Sheet - Shows the snapshot: What the company owns (Assets) versus what it owes (Liabilities) and what shareholders own (Equity)

Cash Flow Statement - Shows the movement: Cash from operations, investing, and financing activities

Operating Margin = EBIT / Revenue = $8M /$ 50M = 16%
Net Profit Margin = Net Income / Revenue = $5.625M /$ 50M = 11.25%

From Balance Sheet:

Total Assets = $35M
Total Debt = $11M (short-term$ 1M + long-term $10M)
Equity = $20M
Debt-to-Equity Ratio = $11M /$ 20M = 0.55

📖 Section 3: Financial Ratios - Key Metrics for Decisions

Financial ratios help you quickly assess company performance and compare across companies.

Profitability Ratios

Return on Assets (ROA):

ROA = \frac{\text{Net Income}}{\text{Total Assets}}

\text{CloudTech ROA} = \frac{\$5,625,000}{\$35,000,000} = 16.07\%

Interpretation: CloudTech generates $0.16 profit for every$ 1 of assets. Higher is better.

Return on Equity (ROE):

ROE = \frac{\text{Net Income}}{\text{Shareholders' Equity}}

\text{CloudTech ROE} = \frac{\$5,625,000}{\$20,000,000} = 28.13\%

Interpretation: CloudTech generates $0.28 profit for every$ 1 of equity. This is excellent!

Liquidity Ratios

Current Ratio:

\text{Current Ratio} = \frac{\text{Current Assets}}{\text{Current Liabilities}}

\text{CloudTech} = \frac{\$15,000,000}{\$5,000,000} = 3.0

Interpretation: CloudTech has $3 in current assets for every$ 1 of current liabilities. Very healthy! (Ratio > 1.5 is typically good)

Quick Ratio (Acid Test):

\text{Quick Ratio} = \frac{\text{Current Assets} - \text{Inventory}}{\text{Current Liabilities}}

\text{CloudTech} = \frac{\$15M - \$2M}{\$5M} = \frac{\$13M}{\$5M} = 2.6

Interpretation: Even excluding inventory, CloudTech has strong liquidity.

Leverage Ratios

Debt-to-Equity Ratio:

\text{Debt-to-Equity} = \frac{\text{Total Debt}}{\text{Equity}}

\text{CloudTech} = \frac{\$11,000,000}{\$20,000,000} = 0.55

Interpretation: For every $1 of equity, CloudTech has$ 0.55 of debt. Moderate leverage.

Debt-to-Assets Ratio:

\text{Debt-to-Assets} = \frac{\text{Total Debt}}{\text{Total Assets}}

\text{CloudTech} = \frac{\$11,000,000}{\$35,000,000} = 31.4\%

Interpretation: 31.4% of assets financed by debt, 68.6% by equity.

Efficiency Ratios

Asset Turnover:

\text{Asset Turnover} = \frac{\text{Revenue}}{\text{Total Assets}}

\text{CloudTech} = \frac{\$50,000,000}{\$35,000,000} = 1.43

Interpretation: CloudTech generates $1.43 in revenue for every$ 1 of assets.

Inventory Turnover:

\text{Inventory Turnover} = \frac{\text{COGS}}{\text{Average Inventory}}

\text{CloudTech} = \frac{\$30,000,000}{\$2,000,000} = 15

Interpretation: CloudTech turns over inventory 15 times per year (every 24 days).

Working Capital and Cash Conversion Cycle

\text{Working Capital} = \text{Current Assets} - \text{Current Liabilities}

\text{CloudTech Working Capital} = \$15,000,000 - \$5,000,000 = \$10,000,000

The cash conversion cycle shows how long cash is tied up in operations:

✓ Checkpoint

What you’ve learned:

Profitability ratios: ROA, ROE measure earnings efficiency
Liquidity ratios: Current, quick ratios assess short-term health
Leverage ratios: Debt-to-equity shows financial risk
Efficiency ratios: Asset turnover shows operational effectiveness

CloudTech’s Financial Health: Strong profitability, excellent liquidity, moderate leverage, good efficiency. Well-positioned for growth!

⚠️ Common Mistake: Comparing ratios across different industries without context.

A D/E ratio of 0.55 is moderate for CloudTech (tech company), but would be considered low for a utility company (typically 1.5-2.0) or high for a consulting firm (typically 0.1-0.3).

Always compare ratios to:

Industry averages (not all companies)
Company’s historical trends
Direct competitors

📖 Section 4: Capital Budgeting - Investment Decisions

Should CloudTech invest $10M in a new data center? Capital budgeting answers this question.

The Investment Opportunity

CloudTech’s Data Center Project:

Initial Investment: $10,000,000 (Year 0)
Expected Annual Cash Flows: $3,000,000 per year for 5 years
Required Return (Discount Rate): 12%
Question: Should they invest?

Method 1: Net Present Value (NPV)

NPV is the gold standard for investment decisions.

Formula:

NPV = \sum_{t=1}^{n} \frac{CF_t}{(1 + r)^t} - \text{Initial Investment}

Where:

$CF_t$ = Cash flow at time $t$
$r$ = Discount rate
$t$ = Time period (0, 1, 2, 3…)
$n$ = Number of periods

Decision Rule:

NPV > 0: Accept project (creates value)
NPV < 0: Reject project (destroys value)
NPV = 0: Indifferent (breakeven)

Calculating NPV for CloudTech

Step 1: Set up cash flows

Year 0: -$10,000,000 (initial investment)
Year 1: +$3,000,000
Year 2: +$3,000,000
Year 3: +$3,000,000
Year 4: +$3,000,000
Year 5: +$3,000,000

Step 2: Discount each cash flow to present value

\begin{aligned} \text{Year 0:} & \quad -\$10,000,000 / (1.12)^0 = -\$10,000,000 \\ \text{Year 1:} & \quad \$3,000,000 / (1.12)^1 = \$2,678,571 \\ \text{Year 2:} & \quad \$3,000,000 / (1.12)^2 = \$2,391,582 \\ \text{Year 3:} & \quad \$3,000,000 / (1.12)^3 = \$2,135,341 \\ \text{Year 4:} & \quad \$3,000,000 / (1.12)^4 = \$1,906,554 \\ \text{Year 5:} & \quad \$3,000,000 / (1.12)^5 = \$1,702,281 \end{aligned}

Step 3: Sum all present values

\begin{aligned} NPV &= -\$10,000,000 + \$2,678,571 + \$2,391,582 + \$2,135,341 + \$1,906,554 + \$1,702,281 \\ NPV &= -\$10,000,000 + \$10,814,329 \\ NPV &= \$814,329 \end{aligned}

Decision: Accept the project! NPV = $814,329 > 0

The data center creates $814,329 in value for CloudTech.

Method 2: Internal Rate of Return (IRR)

IRR is the discount rate that makes NPV = 0.

Interpretation: IRR is the project’s expected return.

Decision Rule:

IRR > Required Return: Accept project
IRR < Required Return: Reject project

Finding IRR (requires financial calculator or Excel):

\text{For CloudTech's project:} \\ IRR \approx 15.24\%

Decision: Accept! IRR (15.24%) > Required Return (12%)

Method 3: Payback Period

Payback Period = Time to recover initial investment

CloudTech’s payback:

\begin{aligned} \text{Year 0:} & \quad -\$10,000,000 \\ \text{Year 1:} & \quad -\$10,000,000 + \$3,000,000 = -\$7,000,000 \\ \text{Year 2:} & \quad -\$7,000,000 + \$3,000,000 = -\$4,000,000 \\ \text{Year 3:} & \quad -\$4,000,000 + \$3,000,000 = -\$1,000,000 \\ \text{Year 4:} & \quad -\$1,000,000 + \$3,000,000 = +\$2,000,000 \end{aligned}

Payback Period: 3.33 years (3 years + $1M/$ 3M = 3.33 years)

Limitation: Ignores time value of money and cash flows after payback!

⚠️ Common Mistake: Relying solely on payback period.

Payback period ignores:

Time value of money (treats all dollars equally)
Cash flows after payback point
Risk and required returns

Always use NPV or IRR as primary method. Payback is supplementary.

Practice Exercise

New Project: Initial investment $5M, annual cash flows$ 1.5M for 5 years, discount rate 10%.

Questions:

Calculate NPV
Should you accept?

Solution

1. Calculate NPV:

\begin{aligned} \text{PV of cash flows} &= \$1.5M \times \frac{1 - (1.10)^{-5}}{0.10} \\ \text{PV of cash flows} &= \$1.5M \times 3.791 \\ \text{PV of cash flows} &= \$5,686,500 \end{aligned}

NPV = \$5,686,500 - \$5,000,000 = \$686,500

2. Decision: Accept! NPV = $686,500 > 0

The project creates $686,500 in value.

✓ Checkpoint

What you’ve learned:

Capital budgeting evaluates investment opportunities
NPV is the gold standard (sum of discounted cash flows - investment)
IRR is the project’s expected return rate
Payback period is supplementary (ignores time value)
Accept projects with NPV > 0 or IRR > required return

Progress Check:

You can now:

✓ Understand time value of money
✓ Analyze financial statements and ratios
✓ Evaluate investments using NPV and IRR

Next: Learn how to determine the right discount rate (cost of capital)!

📖 Section 5: Cost of Capital - What Financing Costs

What discount rate should CloudTech use? The answer: Cost of Capital.

What is Cost of Capital?

Cost of Capital is the minimum return a company must earn on investments to satisfy investors.

It represents:

Opportunity cost - Return investors could earn elsewhere
Required return - Compensation for risk
Hurdle rate - Minimum acceptable return for projects

Three Components of Cost of Capital

Cost of Debt ( $r_d$ ) - Interest rate on borrowing
Cost of Equity ( $r_e$ ) - Return required by shareholders
WACC - Weighted average of debt and equity costs

Cost of Debt (After-Tax)

Formula:

\text{After-Tax Cost of Debt} = r_d \times (1 - T)

Where:

$r_d$ = Interest rate on debt
$T$ = Tax rate

Why after-tax? Interest expense is tax-deductible, reducing the effective cost.

CloudTech Example:

\begin{aligned} \text{Interest Expense} &= 500,000 \\ \text{Total Debt} &= 11,000,000 \\ \text{Tax Rate} &= 25\% \end{aligned}

\begin{aligned} \text{Pre-tax Cost of Debt} &= \frac{500,000}{11,000,000} = 4.55\% \\ \text{After-tax Cost of Debt} &= 4.55\% \times (1 - 0.25) = 3.41\% \end{aligned}

CloudTech’s effective cost of debt is 3.41% after tax benefits.

Cost of Equity (CAPM Method)

Capital Asset Pricing Model (CAPM):

r_e = r_f + \beta \times (r_m - r_f)

Where:

$r_e$ = Cost of equity
$r_f$ = Risk-free rate (e.g., government bonds)
$\beta$ = Stock’s systematic risk (beta)
$r_m$ = Expected market return
$(r_m - r_f)$ = Market risk premium

CloudTech Example:

\begin{aligned} \text{Risk-free rate } (r_f) &= 3\% \\ \text{Beta } (\beta) &= 1.2 \text{ (CloudTech is 20\% riskier than market)} \\ \text{Market return } (r_m) &= 10\% \\ \text{Market risk premium} &= 10\% - 3\% = 7\% \end{aligned}

\begin{aligned} r_e &= 3\% + 1.2 \times 7\% \\ r_e &= 3\% + 8.4\% \\ r_e &= 11.4\% \end{aligned}

CloudTech’s cost of equity is 11.4%.

Weighted Average Cost of Capital (WACC)

WACC blends debt and equity costs based on capital structure.

Formula:

WACC = \frac{E}{V} \times r_e + \frac{D}{V} \times r_d \times (1 - T)

Where:

$E$ = Market value of equity
$D$ = Market value of debt
$V$ = $E + D$ (total value)
$r_e$ = Cost of equity
$r_d$ = Cost of debt
$T$ = Tax rate

CloudTech Calculation:

\begin{aligned} \text{Equity (E)} &= \$20,000,000 \\ \text{Debt (D)} &= \$11,000,000 \\ \text{Total Value (V)} &= \$31,000,000 \end{aligned}

\begin{aligned} E/V &= \$20M / \$31M = 64.5\% \\ D/V &= \$11M / \$31M = 35.5\% \end{aligned}

\begin{aligned} r_e &= 11.4\% \\ r_d \text{ (after-tax)} &= 3.41\% \end{aligned}

\begin{aligned} WACC &= (0.645 \times 11.4\%) + (0.355 \times 3.41\%) \\ WACC &= 7.35\% + 1.21\% \\ WACC &= 8.56\% \end{aligned}

CloudTech’s WACC = 8.56%

This is the minimum return CloudTech must earn on investments.

⚠️ Common Mistake: Using book values instead of market values for WACC.

WACC should use market values:

Market value of equity = Stock price × Shares outstanding (NOT book equity from balance sheet)
Market value of debt = Current trading price of bonds (NOT face value)

Book values are historical costs. Market values reflect current investor expectations and opportunity costs. For our CloudTech example, we simplified by using book values, but in practice, always use market values!

Using WACC for Decisions

Rule: Accept projects with return > WACC

CloudTech’s Data Center:

Project IRR = 15.24%
WACC = 8.56%
Decision: Accept! (15.24% > 8.56%)

The project earns more than the cost of capital, creating value.

✓ Checkpoint

What you’ve learned:

Cost of capital is minimum required return
Cost of debt = interest rate × (1 - tax rate)
Cost of equity = CAPM (risk-free + beta × premium)
WACC weights debt and equity costs by proportion
Accept projects with return > WACC

Practice: If a company has 60% equity (cost 12%) and 40% debt (cost 5%), tax rate 30%, what’s WACC?

Solution

\text{After-tax cost of debt} = 5\% \times (1 - 0.30) = 3.5\%

\begin{aligned} WACC &= (0.60 \times 12\%) + (0.40 \times 3.5\%) \\ WACC &= 7.2\% + 1.4\% \\ WACC &= 8.6\% \end{aligned}

The company’s WACC is 8.6%.

📖 Section 6: Capital Structure - Debt vs Equity Decisions

CloudTech needs $10M for the data center. Should they use debt or equity?

Capital Structure Basics

Capital Structure = Mix of debt and equity financing

Trade-offs:

Debt:

✓ Tax-deductible interest (cheaper after-tax)
✓ No ownership dilution
✗ Fixed payments (financial risk)
✗ Bankruptcy risk if can’t pay

Equity:

✓ No fixed payments (flexible)
✓ No bankruptcy risk
✗ Expensive (higher required return)
✗ Ownership dilution

Financial Leverage

Leverage amplifies returns (good times) and losses (bad times).

Example: CloudTech considers two financing options:

Option A: All Equity ( $20M equity,$ 0 debt) Option B: 50% Debt ( $10M equity,$ 10M debt @ 5%)

Scenario 1: Good Year (EBIT = $4M)

Option A (All Equity):
EBIT                    $4,000,000
Interest                        $0
EBT                     $4,000,000
Tax (25%)              ($1,000,000)
Net Income              $3,000,000

ROE = $3M / $20M = 15%

Option B (50% Debt):
EBIT                    $4,000,000
Interest (5% × $10M)     ($500,000)
EBT                     $3,500,000
Tax (25%)                ($875,000)
Net Income              $2,625,000

ROE = $2.625M / $10M = 26.25%

With leverage, ROE increases from 15% to 26.25%!

Scenario 2: Bad Year (EBIT = $1M)

Option A (All Equity):
EBIT                    $1,000,000
Net Income (after tax)    $750,000

ROE = $750K / $20M = 3.75%

Option B (50% Debt):
EBIT                    $1,000,000
Interest                 ($500,000)
EBT                       $500,000
Net Income (after tax)    $375,000

ROE = $375K / $10M = 3.75%

Leverage magnifies both gains and losses!

Optimal Capital Structure

There’s no perfect formula. Companies balance:

Tax benefits of debt (interest deduction)
Financial distress costs (bankruptcy risk)
Agency costs (conflicts between creditors/shareholders)
Industry norms (tech companies: low debt; utilities: high debt)

CloudTech’s Decision:

Current: D/E = 0.55 (moderate)
Industry average: D/E = 0.40 (tech companies use less debt)

Recommendation: Can add some debt (has strong cash flow)
but stay below D/E = 1.0 to maintain flexibility

Financing the $10M Data Center

CloudTech’s Options:

Option 1: All Debt ($10M new debt)

Pros: Tax shield, no dilution
Cons: D/E increases to 1.05 (high for tech)

Option 2: All Equity ($10M new stock)

Pros: Maintains flexibility
Cons: Expensive, dilutes ownership

Option 3: Mix ( $5M debt +$ 5M equity)

Pros: Balanced approach
Cons: Complexity

Recommended: Option 3 (50/50 mix)

Balances tax benefits with financial flexibility.

⚠️ Common Mistake: Thinking “debt is always better because it’s cheaper.”

While debt has tax benefits and lower cost than equity, too much debt is dangerous:

Fixed interest payments during bad times (can lead to bankruptcy)
Financial distress costs (legal fees, lost customers, employee turnover)
Loss of financial flexibility (can’t invest in new opportunities)
Increased required return on equity (shareholders demand more return for higher risk)

Optimal capital structure balances benefits and costs - there’s no universal “right” answer!

📖 Section 7: Valuation Basics - What Companies Are Worth

What’s CloudTech worth? Valuation provides the answer.

Valuation Methods

Discounted Cash Flow (DCF) - Intrinsic value based on cash flows
Comparable Company Analysis - Value based on similar companies
Precedent Transactions - Value based on acquisition prices

We’ll focus on DCF - the fundamental approach.

Discounted Cash Flow (DCF) Valuation

Core Idea: A company is worth the present value of all future cash flows.

Formula:

\text{Company Value} = \text{PV of Future Free Cash Flows} + \text{Terminal Value}

Free Cash Flow (FCF):

FCF = \text{Operating Cash Flow} - \text{Capital Expenditures}

FCF is cash available to all investors (debt and equity).

CloudTech DCF Valuation

Step 1: Project Future Free Cash Flows (5 years)

\begin{aligned} \text{Current FCF} &= \$6,000,000 \\ \text{Growth rate} &= 8\% \text{ per year} \end{aligned}

\begin{aligned} \text{Year 1:} & \quad \$6,000,000 \times 1.08 = \$6,480,000 \\ \text{Year 2:} & \quad \$6,480,000 \times 1.08 = \$6,998,400 \\ \text{Year 3:} & \quad \$6,998,400 \times 1.08 = \$7,558,272 \\ \text{Year 4:} & \quad \$7,558,272 \times 1.08 = \$8,162,934 \\ \text{Year 5:} & \quad \$8,162,934 \times 1.08 = \$8,815,968 \end{aligned}

Step 2: Calculate Terminal Value (value after Year 5)

Gordon Growth Model:

\text{Terminal Value} = \frac{FCF_{n+1}}{WACC - g}

Where:

$FCF_{n+1}$ = Year 5 FCF $\times$ (1 + perpetual growth rate)
$WACC$ = 8.56%
$g$ = Long-term growth rate = 3%

FCF_{Year6} = \$8,815,968 \times 1.03 = \$9,080,447

\begin{aligned} \text{Terminal Value} &= \$9,080,447 / (0.0856 - 0.03) \\ \text{Terminal Value} &= \$9,080,447 / 0.0556 \\ \text{Terminal Value} &= \$163,314,749 \end{aligned}

Step 3: Discount Everything to Present Value

WACC = 8.56\%

\begin{aligned} \text{PV Year 1} &= \$6,480,000 / 1.0856 = \$5,968,486 \\ \text{PV Year 2} &= \$6,998,400 / (1.0856)^2 = \$5,938,746 \\ \text{PV Year 3} &= \$7,558,272 / (1.0856)^3 = \$5,909,982 \\ \text{PV Year 4} &= \$8,162,934 / (1.0856)^4 = \$5,882,177 \\ \text{PV Year 5} &= \$8,815,968 / (1.0856)^5 = \$5,855,317 \\ \text{PV Terminal Value} &= \$163,314,749 / (1.0856)^5 = \$108,157,524 \end{aligned}

Step 4: Sum to Get Enterprise Value

\begin{aligned} \text{Enterprise Value} &= \$5,968,486 + \$5,938,746 + \$5,909,982 + \$5,882,177 + \$5,855,317 + \$108,157,524 \\ \text{Enterprise Value} &= \$137,712,232 \end{aligned}

Step 5: Calculate Equity Value

\text{Equity Value} = \text{Enterprise Value} - \text{Net Debt}

\begin{aligned} \text{Net Debt} &= \text{Total Debt} - \text{Cash} \\ \text{Net Debt} &= \$11,000,000 - \$5,000,000 = \$6,000,000 \end{aligned}

\text{Equity Value} = \$137,712,232 - \$6,000,000 = \$131,712,232

CloudTech’s Equity Value ≈ $131.7 million

	style A fill:#0173B2,stroke:#000000,color:#FFFFFF
	style F fill:#029E73,stroke:#000000,color:#FFFFFF

Sensitivity Analysis

Valuation depends on assumptions. Test different scenarios:

If WACC changes:

WACC 7.5%: Equity Value = $155M (higher value, lower discount rate)
WACC 9.5%: Equity Value = $115M (lower value, higher discount rate)

If growth rate changes:

Growth 6%: Equity Value = $120M
Growth 10%: Equity Value = $145M

⚠️ Common Mistake: Garbage in, garbage out!

DCF is only as good as your assumptions:

Be conservative with growth rates
Use realistic discount rates
Test sensitivity to key assumptions
Cross-check with comparable company multiples

Quick Valuation Multiples

Alternative approach: Use market multiples

\text{EV/EBIT Multiple} = \frac{\text{Enterprise Value}}{\text{EBIT}}

\begin{aligned} \text{Industry average EV/EBIT} &= 15x \\ \text{CloudTech EBIT} &= \$8,000,000 \end{aligned}

\text{Estimated Enterprise Value} = 15 \times \$8,000,000 = \$120,000,000

This provides a quick sanity check on DCF valuation.

✓ Checkpoint

What you’ve learned:

DCF values companies based on future cash flows
Free cash flow = Operating cash - CapEx
Terminal value captures value beyond forecast period
Enterprise value - debt = Equity value

Multiples provide quick valuation checks

🎯 Practice Challenges

Apply your corporate finance knowledge!

Challenge 1: Time Value of Money

You have three investment options:

Receive $10,000 today
Receive $12,000 in 2 years
Receive $15,000 in 4 years

Discount rate = 8%. Which option is best?

Solution

Calculate present value of each:

Option 1: $10,000 (already in present value)

Option 2:

\begin{aligned} PV &= \frac{\$12,000}{(1.08)^2} \\ PV &= \frac{\$12,000}{1.1664} \\ PV &= \$10,288.07 \end{aligned}

Option 3:

\begin{aligned} PV &= \frac{\$15,000}{(1.08)^4} \\ PV &= \frac{\$15,000}{1.3605} \\ PV &= \$11,025.12 \end{aligned}

Best option: Option 3 ( $15,000 in 4 years has highest PV of$ 11,025.12)

Challenge 2: NPV Analysis

A project requires $50,000 initial investment and generates:

Year 1: $15,000
Year 2: $20,000
Year 3: $25,000
Year 4: $15,000

Discount rate = 10%. Should you accept?

Solution

Discount each cash flow:

\begin{aligned} \text{Year 1:} & \quad \$15,000 / 1.10 = \$13,636.36 \\ \text{Year 2:} & \quad \$20,000 / (1.10)^2 = \$16,528.93 \\ \text{Year 3:} & \quad \$25,000 / (1.10)^3 = \$18,782.87 \\ \text{Year 4:} & \quad \$15,000 / (1.10)^4 = \$10,245.20 \end{aligned}

\text{Total PV} = \$59,193.36

NPV = \$59,193.36 - \$50,000 = \$9,193.36

Decision: Accept! NPV = $9,193.36 > 0

The project creates $9,193.36 in value.

Challenge 3: WACC Calculation

Company XYZ has:

Equity: $80M (cost = 13%)
Debt: $40M (interest rate = 6%)
Tax rate: 30%

Calculate WACC.

Solution

\text{Total Value (V)} = \$80M + \$40M = \$120M

\begin{aligned} E/V &= \$80M / \$120M = 66.67\% \\ D/V &= \$40M / \$120M = 33.33\% \end{aligned}

\text{After-tax cost of debt} = 6\% \times (1 - 0.30) = 4.2\%

\begin{aligned} WACC &= (0.6667 \times 13\%) + (0.3333 \times 4.2\%) \\ WACC &= 8.67\% + 1.40\% \\ WACC &= 10.07\% \end{aligned}

Company XYZ’s WACC = 10.07%
