calculate the total interest that you will have paid once the mortgage is paid off. There is not a function for this, so you will have to enter the formula into the cell. Also, for each scenario calculate the total cost of the home purchase for each scenario (down payment plus principal [loan amount] plus interest.).

You are planning to purchase a house that costs $480,000. You plan to put 20% down and borrow the remainder. Based on your credit score, you believe that you will pay 3.99% on a 30-year mortgage.

You want to determine whether or not you should save some of your money and put only 10% down on your house. Because you are only putting 10% down, lenders require that you purchase private mortgage insurance (PMI). Assume that PMI is 1% of the mortgage amount.

Calculate your total monthly payment (mortgage payment plus PMI).

Calculate the total cost of financing your home purchase (interest plus PMI).

Calculate the total cost of the home purchase. (Down payment plus principal [loan amount] plus interest plus PMI.)

Compare this to the costs associated with a 20% down payment.
