Blammo, inc. has a target capital structure of 30% debt and 70% equity. the firm is planning to invest in a project that will necessitate raising new capital. new debt will be issued at a before-tax yield of 14%, with a coupon rate of 10%. the equity will be provided by internally generated funds so no new outside equity will be issued. if the required rate of return on the firm's stock is 22% and its marginal tax rate is 35%, compute the firm's cost of capital. a) 18.00%b) 18.13%c) 19.68%d) 15.55%

option (B) 18.13%

Explanation:

Given:

Cost of debt = 30%

Cost of equity = 70%

New debt will be issued at a before-tax yield = 14%

coupon rate = 10%

Required rate of return on the firm's stock = 22%

marginal tax rate = 35%

Now,

the firm's cost of capital is calculated as :

= ( Cost of Debt × (1-Tax Rate) × Weight of Debt ) + ( Cost of Equity × Required rate of return on stocks ) × 100%

on substituting the respective values, we get

= 30% × (1-0.35) × 14%  + ( 70% × 22% )

or

= ( 0.3 × 0.65 × 0.14 + 0.7 × 0.22 ) × 100%

or

the firm's cost of capital = 18.13%

hence, the correct answer is option (B) 18.13%
