Determine the monthly principal and interest payment for a 20-year mortgage when the amount financed is $\$ 365,111$ and the annual percentage rate (APR) is 5.4\%.
Round to the nearest cent ( 2 decimal places).
$\square$
Solution
Solution Steps
Step 1: Convert the annual rate to a monthly rate and the term in years to months
To find the monthly payment, we first convert the annual percentage rate (APR), 5.4%, to a monthly rate by dividing by 1200. This gives us \(r' = \frac{5.4}{1200} = 0.0045\).
Next, we convert the term of the mortgage from years to months by multiplying by 12. So, \(n' = n \times 12 = 240\) months.
Step 2: Apply the mortgage payment formula
The monthly payment \(M\) can be calculated using the formula:
\[M = P \frac{r'(1 + r')^{n'}}{(1 + r')^{n'} - 1}\]
Substituting the values, we get \(M = 365111 \times \frac{0.0045 \times (1 + 0.0045)^{240}}{(1 + 0.0045)^{240} - 1} = 2490.98\).
Final Answer:
The monthly principal and interest payment for the mortgage is $2490.98.
