Definition
The Weighted Average Cost of Capital (WACC) is a measure of the average rate of return a company is expected to provide to all its stakeholders, including debt holders, equity investors, and preferred equity investors. It is calculated by multiplying the cost of each funding source by its proportional weight and adding the results. This financial metric is used in corporate finance analysis to evaluate investment decisions, and it reflects the company’s cost of funding.
Key Takeaways
- Weighted Average Cost of Capital (WACC) represents the average interest rate a company must pay to finance its operations, fund new projects, and expand its business. It is used as a hurdle rate in capital budgeting, where future cash flows are discounted back to the present.
- The WACC calculation includes various sources of finance, such as equity and debt, which are weighted proportionately to reflect their percentage of the total capital structure. Therefore, any changes in the company’s debt or equity ratios can affect the WACC.
- Lastly, the lower the WACC, the cheaper it is for the company to fund new projects. Therefore, a firm will always aim to minimize its WACC to boost its profitability and appeal to potential investors.
Importance
The Weighted Average Cost of Capital (WACC) is crucial in finance because it represents the average rate that a company is expected to pay to finance its assets.
It’s the minimum return that a company must earn on its existing asset base to satisfy its creditors, owners, and other providers of capital, or else they will invest elsewhere.
It provides a benchmark for evaluating the profitability of investment opportunities, assisting in the decision-making process for both capital budgeting and business valuation.
WACC is also used as a discount rate in the determination of net present value of cash flows for discounted cash flow (DCF) analyses, which helps in making investment decisions.
Hence, its calculation and correct interpretation play a pivotal role in strategic financial decisions.
Explanation
The Weighted Average Cost of Capital (WACC) is primarily used as a key indicator in financial investment decision making. The main purpose is to assess whether a particular investment is worthwhile by comparing its projected return with the WACC.
If the projected return on an investment exceeds the WACC, the investment is deemed worthwhile as it is expected to yield a profit beyond the cost of funding. Conversely, if the projected return is less than the WACC, the investment would generally not be pursued as it is not expected to generate enough returns to offset the cost.
Further, WACC is employed for corporate valuation and capital budgeting purposes. In corporate valuation, the free cash flow to the firm or the equity cash flows are often discounted at the WACC to obtain the present value of a business’s operations or equity.
Additionally, WACC is also used in the decision making process of capital budgeting where companies use it to decide whether to proceed with a particular project. Thus, WACC holds a crucial spot in the tools used for decision making in finance.
Examples of Weighted Average Cost of Capital
Macy’s Department Store: Macy’s WACC might be calculated using the costs of its various funding sources: long-term debt, common stock, and preferred stock. The company can calculate the percentage of each source in their total capital structure, and sequentially apply the appropriate cost to each component (interest rate for debt, cost of equity calculated by CAPM, and dividend yield for preferred stock.) After computing the weighted cost of each component, they combine these values to define the company’s total WACC. This figure can then be used to assess investment projects or recapitalization plans.
Google’s Parent Company, Alphabet Inc.: Alphabet Inc. may use WACC when deciding whether they should pursue a new project, like developing a new application or buying a smaller tech company. The capital for these projects may come from a mixture of equity and debt. Alphabet then calculates the average cost of this capital taking into account the proportion that each source contributes. If the new project’s rate of return is higher than Alphabet’s WACC, it makes sense to pursue the project.
A Real Estate Firm: Consider a large real estate development firm that finances its projects through a mixture of bank loans, issues of bonds, and equity from shareholders. To determine the feasibility and profitability of a new building project, the firm would calculate their WACC to get a sense of the rate of return they need the project to generate. When the potential return on the proposed project (calculated through revenue projections and other financial analysis) exceeds the firm’s WACC, it would be considered a worthwhile undertaking.
FAQs on Weighted Average Cost of Capital
What is the Weighted Average Cost of Capital (WACC)?
The Weighted Average Cost of Capital, or WACC, is a calculation of a firm’s cost of capital in which each category of capital is proportionately weighted. It includes all sources of finance such as common stock, preferred stock, bonds, and any other long-term debt.
Why is WACC important?
WACC is an important factor in financial modeling and is widely used for discount cash flows (DCF) in order to determine a business’s net present value (NPV). It also aids in making sound investment decisions, as it shows the return that a company must earn to meet its cost of capital.
How is WACC calculated?
WACC is calculated by multiplying the cost of each capital source (equity and debt) by its relevant weight, and then adding the products together to determine the value. The typical formula for calculating WACC is: [(% Cost of Equity x Weight of Equity) + (% Cost of Debt x Weight of Debt x (1 – Tax Rate))]
What factors can affect the WACC?
Several factors can affect WACC, such as company’s debt levels, cost of equity, cost of debt, company’s risk profile, and the rate of Corporation Tax in the country where the company operates.
What is a good WACC percentage?
A “good” WACC varies based on industry and the risk associated with a particular company. In general, a WACC in the range of 5%-10% is often considered acceptable, although it may be higher or lower depending on the circumstances.
