Answer:
8.53% and 5.54%
Step-by-step explanation:
In this question, we use the Rate formula which is shown in the spreadsheet.
The NPER represents the time period.
Given that,
Present value = $1000 × 95% = $950
Assuming figure - Future value or Face value = $1,000
PMT = 1,000 × 8% = $80
NPER = 20 years
The formula is shown below:
= Rate(NPER;PMT;-PV;FV;type)
The present value come in negative
So, after solving this,
1. The pretax cost of debt is 8.53%
2. And, the after tax cost of debt would be
= Pretax cost of debt × ( 1 - tax rate)
= 8.53% × ( 1 - 0.35)
= 5.54%
