Definition
The cost of capital formula is used to calculate the total cost of financing a business, which can include equity and debt. It is typically calculated as the weighted average cost of debt and equity, where the proportions of debt and equity used are their respective proportions in the total capital structure. The formula is: Cost of Capital = (Cost of Equity * Proportion of Equity) + (Cost of Debt * Proportion of Debt * (1 – Tax Rate)).
Key Takeaways
- The Cost of Capital Formula is a financial metric used by companies to evaluate and decide on investment opportunities or projects. It calculates the cost for an organization to finance its operations and growth by using different sources of funding – debt, equity or retained earnings.
- This formula provides an estimation of the minimum return an investment should make to break even, considering the cost of using capital. It plays a vital role in decision-making regarding financing the business. A lower cost of capital indicates a less risky investment.
- The formula for Cost of Capital comprises the Weighted Average Cost of Capital (WACC), which includes the cost of equity, cost of debt, and their respective weightages. This framework ensures that all sources of capital are taken into consideration, providing a more holistic view of a company’s financial health and future investment policies.
Importance
The Cost of Capital formula is an important finance term as it allows businesses to make informed investment decisions and determine their ability to achieve their financial goals.
It refers to the expected returns on the capital invested in a business, which may be in the form of debt, equity, or a combination of both.
The formula greatly helps businesses to evaluate new projects by comparing the cost of capital with the expected rate of return on new investment.
If the expected rate of return is higher than the cost of capital, then the project may be seen as a profitable venture.
This strategic tool not only promotes effective risk management but also optimizes the capital structure and enhances the value of a firm.
Explanation
The Cost of Capital Formula is primarily utilized in corporate finance to determine the company’s ability to create value for its shareholders. The purpose of this key concept in finance is to evaluate potential investment projects and acquisitions, and to determine the firm’s optimal capital structure. It serves as the yardstick for various corporate financial activities like dividend policy formulation, budget preparation, capital budgeting, and other financial decision-making processes.
Essentially, it assists companies in understanding the minimum return they should aim to achieve to satisfy their investors, and thus, allows them to make investments that are not only profitable but also feasible. Moreover, the Cost of Capital Formula aids businesses in finding an ideal balance between the risk and return of financing their operations via different funding sources such as equity, debt, or a combination of both. For instance, while borrowing can be a cheaper way of financing, it also increases risk given that it has to be paid back regardless of the performance of the business.
Equity raises funds without increasing debt, but dilutes the ownership, claims on profits, and control of the company. Therefore, the cost of capital encompasses both these elements and provides a more comprehensive view of what it costs for a company to operate. It plays a crucial role in allowing companies to build optimal financial strategies and make key business decisions.
Examples of Cost of Capital Formula
Construction Companies: Suppose a construction company wants to finance a new project. The total estimate for the project will be $5 million. The firm expects the cost of the project to be financed as follows: $2 million from retained earnings (equity: the cost being 8% which is the ROI that the firm must give to its investors) $5 million from preferred stock (equity: the cost being 10% which is the dividend rate on preferred stock) $5 million from long-term bonds (debt: after-tax cost being 5% which is the interest on a long-term bond) The cost of capital would be calculated as follows: WACC = (E/V * Re) + (D/V * Rd) Where, E = Market value of equity (retained earnings + preferred stock) = $2 million + $5 million = $5 million D = Market value of debt = $5 million Re = Cost of equity = (2/
5 * 8) + (5/5 * 10) =57% +29% =86% Rd = Cost of debt after taxes = 5% V = Total Market Value = E + D = $
5 million + $5 million = $5 millionHence, the WACC = (5/5 *86%) + (5/5 * 5%) ≈42%.
Tech Startup: Suppose a technology startup plans to raise funds for an expansion plan. The funds are to be collected from three sources: issuing new common stock ($15 million at a cost of 12%), retained earnings ($8 million at a cost of 10%), and a bank loan ($7 million at a cost of 5%). The company computes its WACC to understand the overall cost of capital.Pharmaceutical Company: Suppose a pharmaceutical company wants to initiate R&D for a new drug. The R&D is expected to cost $10 million. The company plans to finance the cost through equity capital ($6 million at cost 9%) and debt ($4 million at 7% after-tax cost). The WACC is computed to understand the actual cost to the company.
