Cost of capital is the rate that must be earned on an investment project if the project is to increase the value of the common stockholder’s investment and is also is the key determinant of the capital cost associated with a firm’s investment. 12-2. Why do we calculate a firm’s weighted average cost of capital?

The flotation cost will decrease the amount of capital that a firm can work with, but must be include in the cost of capital. For example, if a firm issued stock at $12 a share with a 10% rate of return, but incurs a transaction cost of $2 a share. The firm needs to earn $1.20 to satisfy the investors. Yet the flotation cost lowered the firm’s money to $10 a share, so the rate of return must be 12%. Thus the flotation cost affects the cost of capital. ...
