Answer:
4.24%
Explanation:
The computation of the after tax cost of debt is given below:
But before that we have to determine the before tax of debt by using RATE formula
Given that
Future value be $100
Present value be $105
PMT is $100 × 6.5% = $6.5
NPER is 20
The formula is
=RATE(NPER,PMT,-PV,FV,TYPE)
After applying the above formula, the before tax cost of debt is 6.06%
Now the after tax cost of debt is
= 6.06% × (1 - 0.30)
= 4.24%
