PMT is the mortgage payment amount.

PV is the present value.

n is the number of mortgage payments.

i is the period interest rate.


Question: Suppose you wish to acquire a car that costs $34550. And to make the down payment of $1000 along with the interest of 2% on 3 years with a $15500 loan.


Given, Interest = 2%, Mortgage amount = $34550, Mortgage term = 3 years.

As we know the mortgage monthly payment formula,

PMT = PV i(1+i)n/ (1+i)n - 1

= [$15500 * (0.02/12)( 1+ 0.02/12)36] / [( 1+ 0.02/12)36 - 1]

= [$15500 * (0.001)( 1+ 0.001)36] / [( 1+ 0.001)36 - 1]

Monthly payment = $ 989.60
