Advanced Mortgage Calculator allows the following: adjustment for inflation, tax, insurance, currency type, start year, end year, start month, table type, and prepayment options. You can select from several different tools to see how good your mortgage is or how it compares to others. Three types of graphing analysis are avialable: Pie chart -- principle vs interest Balance -- shows the current balance Principle -- shows the current principle Balance/Principle -- shows both the principle and balance together which makes a bow tie in some cases. Sliders are available in order to dynamically calculate the mortgage, or you can type the mortgage into the textboxes if desired. This calcualator will do about anything you'll ever want from a mortgage calculator.
