Unformatted text preview: If we then add the risk-free interest rate, we arrive at the cost of capital: Cost of capital = rf + β asset (rm - rf) β Suppose the expected risk-free rate of interest is 4 percent and the expected return on the market as a whole is 10 percent. If the basset is 2.00, this means that if there is a 1 percent change in the market risk premium, we expect a 2 percent change in the return on the project. In this case, the cost of capital is 16 percent: Cost of capital = 0.04 + 2.00 (0.10 - 0.04) = 0.16 or 16% If asset beta is 0.75, instead, the cost of capital is 8.5 percent: Cost of capital = 0.04 + 0.75 (0.06) = 0.085 or 8.5% If we are able to gauge the market risk of a project, we estimate the risk-free rate and the premium for market risk and put them together. But often we are not able to measure the market risk, nor even the risk-free rate. So we need another way to approach the estimation of the project's cost of capital. C. Adjusting the company's cost of capital Another way to estimate the cost of capital for a project without estimating the risk premium directly is to use the company's average cost of capital as a starting point. The average cost of capital is the company's marginal cost of raising one more dollar of capital -- the cost of r...
