Tutorial 14

**An "interest only" mortgage or loan is a debt with a periodic payment that is equal to the interest due**. At the end of the term, the entire principal balance is due. There are variations that allows for some initial number of payments to be interest only payments followed by a set number of principal and interest payments. The Ultimate Financial Calculator can handle any variation of interest only calculations.

This example applies to our online Ultimate Financial Calculator. The C-Value! program for Windows works in a similar way and has a few more features including the ability to save your work.

All users should work through the first tutorial to understand basic concepts about the calculator.
