Procedure: In our brief case study, we assume the Thomas and Jefferson families have identical mortgages (30-year term, fixed-rate 6% APR, and a loan amount of $175,000). The Thomas family will not pay extra but the Jeffersons will. Follow the steps below prior to your analysis. 1. Using the Payment mini calculator of the Financial Toolboxes spreadsheet, calculate the mortgage payment (the same for both families). Required Monthly Payment = $ 2. Assume that the Thomas's will make only the required mortgage payment. The Jeffersons, however, would like to pay off their loan carly. They decide to make the equivalent of an extra payment each year by adding an extra 1/12 of the payment to the required amount Complete the following calculations to find what they plan to pay each month: a. 1/12 of the required monthly payment = $ b. By adding this 1/12 to the required payments, the Jeffersons plan to pay $ each month 3. The Thomas's will take the full 30 years to pay off their loan, since they are making only the required payments. The Jefferson's extra payment amount, on the other hand, will allow them to pay off their loan more rapidly. Use the Years mini financial calculator of the Financial Toolbox spreadsheet to calculate the approximate number of years (nearest 10) it would take the Jeffersons to pay off their loan.
