WACC Calculator (Weighted Average Cost of Capital)
About
The Weighted Average Cost of Capital (WACC) is a critical financial metric that helps businesses assess their cost of capital from various sources. It provides a comprehensive view of how much a company needs to earn to satisfy its investors, encompassing equity, debt, and preferred equity. Businesses employ WACC as a hurdle rate for investment decisions, indicating the minimum return they must earn on investments to be attractive to investors. Understanding how to calculate and utilize WACC effectively can have a substantial impact on your investment strategies and business growth.
How to Use
Using a WACC calculator is straightforward and involves inputting the following fundamental values:
- Equity Value – The market capitalization of your equity.
- Debt Value – The total outstanding debt of the company.
- Cost of Equity – The return required by equity investors.
- Cost of Debt – The effective rate that the company pays on its current debt.
- Tax Rate – The tax rate applicable to the company’s income.
Most online WACC calculators require you to fill in these fields and will provide you with the WACC percentage, making it easy for you to evaluate your investment costs.
Formula
The formula for calculating WACC is:
WACC = (E/V * Re) + (D/V * Rd * (1 – Tc))
Where:
- E = Market value of equity
- D = Market value of debt
- V = E + D (total market value of the firm’s financing)
- Re = Cost of equity
- Rd = Cost of debt
- Tc = Corporate tax rate
Example Calculation
Let’s assume a company has the following financials:
- Market Value of Equity (E) = $500,000
- Market Value of Debt (D) = $300,000
- Cost of Equity (Re) = 8%
- Cost of Debt (Rd) = 5%
- Corporate Tax Rate (Tc) = 30%
To calculate the WACC:
V = E + D = 500,000 + 300,000 = 800,000
WACC = (500,000 / 800,000 * 0.08) + (300,000 / 800,000 * 0.05 * (1 – 0.30))
WACC = (0.625 * 0.08) + (0.375 * 0.05 * 0.7)
WACC = 0.05 + 0.013125 = 0.063125
WACC = 6.31%
The calculated WACC of 6.31% means the company must earn this minimum return on its investments to satisfy its stakeholders.
Limitations
While WACC is a valuable financial metric, it has several limitations:
- Assumption of Market Conditions: WACC assumes that market conditions remain stable, which is often not the case.
- Static Nature: WACC does not account for changes in the risk profile of the company over time.
- Complexities in Debt Valuation: The cost of debt might vary with interest rates and is affected by the credit rating of the company.
Tips for Managing
Managing your WACC effectively can lead to better financial decisions:
- Monitor Changes: Regularly review your debt and equity positions as they can affect your WACC.
- Optimize Capital Structure: Aim for a balanced mixture of debt and equity to minimize the total WACC.
- Utilize Financial Advisors: Consider consulting with financial professionals for accurate assessments and strategies.

WACC is used extensively in various scenarios, including:
- Project Valuation: Used as a discount rate in net present value calculations.
- Universal Comparison: A benchmark for comparing the cost of capital among companies in the same industry.
- Capital Structure Decisions: Helps in making decisions about the optimal financing mix.
Key Benefits
