Part 1: Create an Excel spreadsheet that will calculate an amortization table for a fixed rate loan. This spreadsheet should work for fully amortizing, partially amortizing, and non-amortizing loans by allowing the user to adjust FV. All inputs should be clearly labeled and easily accessible by the user. To evaluate your spreadsheet, you may start by looking at a $1,000,000 fully amortizing, fixed rate mortgage with a 10 year term, monthly payments, and an interest rate of 6%. The spreadsheet should still fully function if I change any of these terms.

Part 2: Add the ability for your spreadsheet to calculate the effective rate for a loan incorporating any closing costs. This should not be an entirely new sheet, but rather a modification of your existing spreadsheet. Assume the loan in part 1 now has closing costs of $12,000. To keep things simple, the spreadsheet only has to calculate the effective rate if the loan is held until maturity.
