Answer:
component cost of debt to calculate wacc = 0.7
Explanation:
given data
par value = $1000
time = 20 year
rate = 7%
tax rate = 40%
tax rate = 30 %
to find out
cost of debit use to calculate wacc
solution
we know cost of debt before tax is 7%
so when tax is 30 % cost of debt after tax is = 7% ( 1 - tax rate )
cost of debt after tax = 7% ( 1- 0.30 )
cost of debt after tax = 4.9 .......................1
and
so when tax is 40 % cost of debt after tax is = 7% ( 1 - tax rate )
cost of debt after tax = 7% ( 1- 0.40 )
cost of debt after tax = 4.2 .......................2
so
from equation 1 and 2
component cost of debt to calculate wacc = 4.9 - 4.2
component cost of debt to calculate wacc = 0.7
