Definition§
Marginal Cost of Capital refers to the cost of acquiring an additional dollar of new capital. This is important in the context of business finance as it helps to determine the effective cost of supporting new projects and investments. Not all sources of capital cost the same; for instance, financing through low-grade subordinated debt often demands a higher interest rate compared to unsubordinated debt. Companies utilize the marginal cost of capital to identify the appropriate hurdle rate used in discounted cash flow (DCF) and present value (PV) analyses. This approach ensures that the company accurately reflects the cost of financing when evaluating the profitability and feasibility of new investments.
Examples§
-
New Project Financing: A company planning to undertake a new project may seek additional capital from various sources such as equity, bonds, or loans. If the next dollar of financing is obtained through issuing new shares, the marginal cost of capital could involve the expected return demanded by new shareholders.
-
Debt Financing: Imagine a company that has exhausted its allotment of safe, low-interest loans. The company may need to issue subordinated debt, which has a higher interest rate. This higher rate represents the marginal cost of using this new source of capital.
Frequently Asked Questions§
Q: Why is the marginal cost of capital important?
A: It helps businesses determine the cost associated with raising an additional dollar of capital, ensuring the appropriate hurdle rate is used when evaluating new investments.
Q: How does marginal cost of capital differ from average cost of capital?
A: The average cost of capital considers the overall cost of all financing sources, while the marginal cost of capital focuses on the cost of the next dollar raised, which may come from different sources and at varied costs.
Q: What is a hurdle rate?
A: The hurdle rate is the minimum acceptable return on an investment, used as a benchmark in discounted cash flow analysis to evaluate the potential profitability of a project.
Q: Can the marginal cost of capital affect investment decisions?
A: Yes, it directly impacts the hurdle rate, and thus, the present value calculations for prospective projects, influencing whether a project meets the profitability criteria.
