1. About

The Cost of Capital represents the cost of funds used for financing a business. It includes the cost of debt and the cost of equity, and understanding it is crucial for companies to evaluate investment opportunities and make strategic financial decisions. This calculator helps businesses determine their cost of capital efficiently, enabling better investment choices that align with their financial strategy.

2. How to Use the Cost of Capital Calculator

Using the cost of capital calculator is straightforward and user-friendly. Follow these simple steps:

1. Input Debt Information: Enter the total amount of debt and the interest rate.
2. Input Equity Information: Enter the total equity and the expected rate of return for equity investors.
3. Weighting: Specify the proportion of debt and equity in your capital structure.

3. Formula

The formula for calculating the cost of capital can be expressed as follows:

WACC = (E/V * Re) + (D/V * Rd * (1 – Tc))

Where:

• WACC: Weighted Average Cost of Capital
• E: Market value of equity
• V: Total market value of the firm’s financing (Equity + Debt)
• Re: Cost of equity
• D: Market value of debt
• Rd: Cost of debt
• Tc: Corporate tax rate

4. Example Calculation

Let’s assume a company has the following financial data:

• Total Debt (D): $300,000
• Interest Rate (Rd): 5%
• Total Equity (E): $700,000
• Cost of Equity (Re): 10%
• Corporate Tax Rate (Tc): 30%

Step 1: Calculate Total Value (V):

V = E + D = $700,000 + $300,000 = $1,000,000

Step 2: Compute WACC:

WACC = (700,000/1,000,000 * 10%) + (300,000/1,000,000 * 5% * (1 – 0.30))

WACC = (0.7 * 0.1) + (0.3 * 0.05 * 0.7)

WACC = 0.07 + 0.0105 = 0.0805 or 8.05%
