Answer:
$349.40
Step-by-step explanation:
The interest in 72 month is only obtained when an amortization table for this mortgage is constructed.
So we first need to find the annual instalment as follows :
PV = $150,000
i = 3.21%
N = 30
P/YR = 1
FV = $ 0
PMT = ?
Using a financial calculator to input the values as above, the annual instalment is $7,862.08.
In 72 months, this will be 6 years. So in the 6th year, the interest will be $4,293.52. Monthly interest will approximate $349.40 ($4,293.52 ÷ 12).
