Calculate Weighted Average Cost of Capital Example (WACC)
Use this professional calculator to determine the Weighted Average Cost of Capital (WACC) for corporate finance analysis. Simply input equity, debt, and rate values below to see the result instantly.
Formula: WACC = (E/V × Re) + ((D/V × Rd) × (1 – T))
| Component | Market Value | Weight | Cost (%) | Contribution (%) |

What is Calculate Weighted Average Cost of Capital Example?
When financial analysts or business owners need to assess the expense of funding operations, they often look for a way to calculate weighted average cost of capital example. The Weighted Average Cost of Capital (WACC) is a financial metric that represents the average rate a company is expected to pay to finance its assets. It is calculated by averaging the cost of all sources of capital—namely equity and debt—weighted by their respective proportions in the company's capital structure.
Understanding how to calculate weighted average cost of capital example scenarios is crucial for investment decisions. It serves as the "hurdle rate" for companies; if a new project cannot generate a return (ROI) higher than the WACC, it will essentially destroy shareholder value. This metric is widely used by CFOs, investment bankers, and equity research analysts to discount future cash flows in Discounted Cash Flow (DCF) models.
A common misconception is that WACC is static. In reality, it changes as market conditions fluctuate (affecting interest rates) or as the company's risk profile alters its cost of equity.
WACC Formula and Mathematical Explanation
To properly calculate weighted average cost of capital example figures, one must understand the standard mathematical formula. The formula blends the cost of equity and the after-tax cost of debt based on how much the company relies on each.
WACC = (E/V × Re) + ((D/V × Rd) × (1 – T))
Where:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| E | Market Value of Equity | Currency ($) | > 0 |
| D | Market Value of Debt | Currency ($) | ≥ 0 |
| V | Total Capital (E + D) | Currency ($) | > 0 |
| Re | Cost of Equity | Percent (%) | 6% – 15% |
| Rd | Cost of Debt | Percent (%) | 3% – 10% |
| T | Corporate Tax Rate | Percent (%) | 15% – 30% |
Table 2: Key variables required to calculate weighted average cost of capital example.
Step-by-Step Derivation
- Determine Total Value (V): Add the market value of equity and debt.
- Calculate Weights: Divide Equity by Total Value (E/V) and Debt by Total Value (D/V).
- Determine Costs: Estimate Cost of Equity (often using CAPM) and identify the Cost of Debt (interest rate).
- Apply Tax Shield: Multiply the Cost of Debt by (1 – Tax Rate) because interest payments are tax-deductible.
- Sum Products: Multiply weights by costs and add them together.
Practical Examples (Real-World Use Cases)
To illustrate how to calculate weighted average cost of capital example data effectively, let's look at two distinct scenarios.
Example 1: Tech Startup (High Equity, Low Debt)
Imagine "TechNova Inc." is funded primarily by venture capital.
Inputs:
• Equity (E): $10,000,000
• Debt (D): $1,000,000
• Cost of Equity (Re): 15% (High risk)
• Cost of Debt (Rd): 8%
• Tax Rate (T): 25%
Calculation:
Total Value (V) = $11,000,000
Weight of Equity = 10/11 ≈ 90.9%
Weight of Debt = 1/11 ≈ 9.1%
After-Tax Cost of Debt = 8% × (1 – 0.25) = 6%
WACC = (0.909 × 15%) + (0.091 × 6%) ≈ 13.64% + 0.55% = 14.19%
Interpretation: TechNova needs projects returning over 14.19% to be viable.
Example 2: Utility Company (Stable, High Debt)
"PowerGrid Corp" has stable cash flows and uses more leverage.
Inputs:
• Equity (E): $50,000,000
• Debt (D): $50,000,000
• Cost of Equity (Re): 8% (Lower risk)
• Cost of Debt (Rd): 5%
• Tax Rate (T): 21%
Calculation:
Total Value (V) = $100,000,000
Weight of Equity = 50%
Weight of Debt = 50%
After-Tax Cost of Debt = 5% × (1 – 0.21) = 3.95%
WACC = (0.50 × 8%) + (0.50 × 3.95%) = 4% + 1.975% = 5.98%
Interpretation: PowerGrid has a much lower hurdle rate due to stable operations and tax shields.

Key Factors That Affect WACC Results
Several macroeconomic and company-specific factors influence the output when you calculate weighted average cost of capital example.
- Interest Rates: As central banks raise rates, the Cost of Debt (Rd) increases, pushing WACC up.
- Stock Market Volatility: Higher volatility increases Beta, which raises the Cost of Equity (Re) via the CAPM model.
- Capital Structure: Increasing debt usually lowers WACC initially because debt is cheaper than equity and offers tax shields. However, excessive debt increases bankruptcy risk, eventually raising both Rd and Re.
- Corporate Tax Rates: Higher tax rates increase the value of the tax shield (interest deduction), effectively lowering the after-tax cost of debt and WACC.
- Company Size: Smaller companies often have a "small stock premium," resulting in a higher Cost of Equity compared to large-cap firms.
- Economic Inflation: Inflation drives up the nominal return required by investors, increasing both equity and debt costs.
