Explanation:
Cost of Financing with :
Retained Earnings or Equity or Common Stock (Ke) = 10%
Preferred Stock (Kp) = 8%
Debt (Kd) = 6% (1- Tax Rate)
Capital structure
Debt:Preferred Stock:Common Stock
40:10:50
Weight of Debt (Wd) = 40%
Weight of Preferred Stock (Wp) = 10%
Weight of Common Stock (We) = 50%
Weighted Average Cost of Capital (WACC) = (Kd x Wd) + (Kp x Wp) +(Ke x We)
(A). Tax Rate = 40% or 0.40
Kd = 6% (1-0.40) = 3.60%
WACC = (Kd x Wd) + (Kp x Wp) +(Ke x We)
= (0.036 x 0.40) + (0.08 x 0.10) + (0.10 x 0.50)
= 7.24 % or 0.0724
(B). Tax Rate = 35% or 0.35
Kd = 6% (1-0.35) = 3.90%
WACC = (Kd x Wd) + (Kp x Wp) +(Ke x We)
= (0.039 x 0.40) + (0.08 x 0.10) + (0.10 x 0.50)
= 7.36 % or 0.0736
(C). Tax Rate = 25% or 0.25
Kd = 6% (1-0.25) = 4.50%
WACC = (Kd x Wd) + (Kp x Wp) +(Ke x We)
= (0.045 x 0.40) + (0.08 x 0.10) + (0.10 x 0.50)
= 7.60% or 0.0760
(D). Interest on debt is a tax deductible expense and if debt is a part of capital structure of a company, it helps in maximisation of wealth of shareholders' of that company as it reduces effective cost of capital by deducting tax component from the overall cost of capital.
In the question, Weight of Debt in Capital remains same, so with decrease in tax rate from part (A) to (C), cost of capital increases due to increase in after tax cost of debt. Or in other words we can say that increase in tax rate reduces cost of cost other things remaining constant.
