What does the cost of capital represent for a company?

The cost of capital represents the minimum return that a company must earn on its investments in order to satisfy its investors, which typically includes both equity shareholders and debt holders. This rate of return is crucial because it serves as a benchmark for evaluating the profitability of projects; if an investment does not generate a return that meets or exceeds this cost, it could detract value from the company and ultimately hurt shareholder interests.

The required return compensates them for these risks and is influenced by various factors, including the company's business risk, the risk-free rate of return, and the equity risk premium.
