Answer:
Step-by-step explanation:
First, find the Pretax cost of debt i.e the YTM.
You can compute this using a financial calculator with the following inputs;
FV = 1,000
N= 10
PMT = 0.11*1000 = 110
PV = -1,278.41
then CPT I/Y = 7.03%
Therefore, the pretax cost of debt = 7.03%
Next, find after-tax cost of debt
After-tax cost of debt = pretax cost of debt (1-tax)
= 7.03% (1-0.25)
= 5.27%
