Fixed Rate Mortgage
Mortgage with constant rate of interest and monthly payments over the entire life of the mortgage. So, there will be no possibility of any balloon payment at the end of the mortgage term.
Interest Only Mortgage
Special type of ARM requires you to pay the monthly interests only and make balloon payment at the end of the term length to adjust the remaining principal balance. This is a combination of fixed and variable rate mortgage because the payment is fixed for a certain time and after that adjustable rates come into play. But this particular calculator will assume that the rate is fixed over the payment period ranging from 1% to 25%.
