Marginal cost of capital (MCC) is the rate of return investors require from a firm to incentivize them to invest in a project. It is essentially the opportunity cost of capital, meaning the profit an investor forgoes by investing in a project instead of earning from other investments.
MCC = E(rf - rc)
E(rf) is the expected return on alternative investments (e.g., bonds, stocks).
rc is the cost of capital, representing the return investors receive from alternative investments.
MCC is a crucial metric for financial management, as it helps firms make informed decisions about capital budgeting and financing. By understanding the marginal cost of capital, companies can determine the most cost-effective mix of investments to maximize returns for shareholders while minimizing risk.
Example:
A firm is considering investing in a project that has an expected return of 15% per year. The firm's cost of capital is 10%. The marginal cost of capital for this project would be 5%, meaning that the firm would have to earn 5% per year to incentivize investors to accept the project
