Answer:
5.925%
Explanation:
For computing the cost of debt, first we have to determine the YTM by using the Rate formula that is shown in the attachment
Given that,
Present value = $1,050
Assuming figure - Future value or Face value = $1,000
PMT = 1,000 × 8% = $80
NPER = 20 year - 1 year = 19 year
= Rate(NPER;PMT;-PV;FV;type)
The present value come in negative
So, after solving this,
1. The pretax cost of debt is 7.50%
2. And, the after tax cost of debt would be
= Pretax cost of debt × ( 1 - tax rate)
= 7.50% × ( 1 - 0.21)
= 5.925%
