Answer:
8% and 4.8%
Explanation:
In this question, we use the Rate formula which is shown in the spreadsheet. Â
The NPER represents the time period. Â
Given that, Â
Present value = $1,294.54
Future value or Face value = $1,000 Â
PMT = 1,000 × 11% = $110
NPER = 20 years
The formula is shown below: Â
= Rate(NPER;PMT;-PV;FV;type) Â
The present value come in negative Â
So, after solving this, Â
1. The pretax cost of debt is 8%
2. And, the after tax cost of debt would be
= Pretax cost of debt × ( 1 - tax rate)
= 8% × ( 1 - 0.40)
= 4.8%
