Claudia, If you have Microsoft Excel on your computer, you have all the calculator you need.
For example: To just calculate the basic payment for a mortgage use the =pmt function. Let's say you have a 30 year fixed mortgage at 5% per year, compounded monthly and the principal is $100,000 you would just type the following into any cell in an Excel spreadsheet. =pmt(5.0%/12,360,100000) There are also functions to calculate how much principal or interest has been paid over a period of time. And, as someone else has mentioned, you can get Excel functions that will produce the entire amortization table, but the three functions I mentioned above give you all the same information. Hope that helps. -- Blue skies. Dan Rossi Carnegie Mellon University. E-Mail: [email protected] Tel: (412) 268-9081
