Answer:
3.20%
Explanation:
For computing the after tax cost of debt we need to use the RATE formula i.e to be shown in the attachment below:
Given that,
Present value = $1,229.24
Future value or Face value = $1,000
PMT = 1,000 × 10% = $100
NPER = 5 years
The formula is shown below:
= Rate(NPER;PMT;-PV;FV;type)
The present value come in negative
So, after applying the above formula
1. The pretax cost of debt is 4.74%
2. And, the after tax cost of debt would be
= Pretax cost of debt × ( 1 - tax rate)
= 4.74% % × ( 1 - 0.25)
= 3.20%
