Final answer:
Dominic's monthly mortgage payment on a 15-year, $240,000 loan with a 6.72% annual interest rate, compounded monthly, is approximately $1,950.22.
Step-by-step explanation:
To calculate the monthly payments on a 15-year mortgage, we need to use the formula for the present value of an ordinary annuity:
R = P [ i(1+i)^n ] / [ (1+i)^n - 1 ]
Where R is the monthly payment,
P is the principal amount of the loan,
i is the monthly interest rate, and
n is the total number of monthly payments.
In this case, P = $240,000,
i = 6.72% / 100
= 0.0672 / 12
= 0.0056, and
n = 15 * 12
= 180.
Plugging in these values, we get:
R = 240000 [ 0.0056(1+0.0056)^180 ] / [ (1+0.0056)^180 - 1 ]
Calculating this expression will give us the monthly payments on the loan.
=1,950.22
So, the monthly mortgage payment for Dominic's 15-year mortgage of $240,000 at an annual interest rate of 6.72 percent, compounded monthly, is approximately $1,950.22.
