Capital Structure

Definition

Capital structure refers to the mix of debt and equity a company uses to finance its operations and growth. It shows how a business chooses to fund its assets—through borrowing, issuing shares, or a combination of both.

The two primary components are:

• Equity: Common stock, preferred stock, retained earnings
• Debt: Short‑term and long‑term interest‑bearing borrowings

Why It Matters

• Determines a company’s overall cost of capital (WACC).
• Influences risk, return, and financial flexibility.
• Affects valuation, credit ratings, and investor perception.
• Helps assess how aggressively or conservatively a company is financed.

How to Interpret It

• More Debt (Leveraged Structure):
  • Lower cost of capital due to tax‑deductible interest
  • Higher financial risk
  • Greater sensitivity to economic downturns
• More Equity (Conservative Structure):
  • Lower financial risk
  • Higher cost of capital (equity is more expensive than debt)
  • More flexibility during downturns
• Optimal Capital Structure:
  • Minimizes WACC
  • Maximizes firm value
  • Balances risk and return

There is no universal “best” structure—industry norms and business models matter.

Key Components

• Debt Ratio:

$$\frac{\text{Total Debt}}{\text{Total Capital}}$$

• Equity Ratio:

$$\frac{\text{Total Equity}}{\text{Total Capital}}$$

• Leverage Metrics: Debt‑to‑Equity, Debt‑to‑Assets, Interest Coverage
• Tax Shield: Debt reduces taxable income through interest deductions.

Example

A company has:

• Total Debt: $400 million
• Total Equity: $600 million

$$\text{Total Capital}=400+600=\mathrm{1,000}\text{million}$$

$$\text{Debt Ratio}=\frac{400}{\mathrm{1,000}}=40\mathrm{\%}$$

$$\text{Equity Ratio}=\frac{600}{\mathrm{1,000}}=60\mathrm{\%}$$

The company’s capital structure is 40% debt and 60% equity, indicating a moderately conservative financing mix.
