Lab Created By: Dand Lippman, Author of Math And Society The goal of this activity is to use Microsoft Excel to find the monthly payment for a loan and then create an amortization schedule. The spreadsheet should be versatile in that you should be able to change input variables and have the spreadsheet recalculate. An example is shown below 1 Cost 2 Down payment 3 Balance B1-B2 Interest (as a decimal) 5 Term (months) PMT(B4/12,85,-B3,0,0 Monthly Pmt Interest 10 Period 12 13 Principal Balance 83 SB$7-B1 D11-C1 2 SB$4/12 D11 -SB$4/12 D12 3 The monthly payment formula is -pMTtrate as a decimal, number of payment period, Present value (negative loan amount), Future Value (0), Payment at end of period (0)) You have decided to buy a house.

Payment number Interest Principal Balance 15 year mortgage 180 30 year mortgage 180 Complete the short answer question in 500 characters using complete sentences: 4.
