Financial Amortization Calculator 2.2a

Heres a simple program that will calculate montly payments, interest rate, number of payments, or affordable principle given the other parameters. You can specify any three of these variables and ask the calculator to determine the fourth. Additionally, it will calculate the remaining principle after a specified number of payments. All calculations are based on "simple interest" calculations (that used for most home mortgages). It does not use the "rule of 78s" that is common among car loans.
A new addition to V2.0 is what Ive called a Uniform Draw-Down Calculator. This will let you calculate how long an initial balance will last if you withdraw a fixed amount each month and the remaining balance earns interest.
