These details result in a more accurate monthly payment estimate than if you simply calculated your mortgage principal and interest. There are two main advantages to a 30-year fixed mortgage: Your payments are lower, and your monthly payments are predictable. A 30-year fixed-rate mortgage has relatively low monthly payments because you're spreading your repayment out over a longer period of time than with, say, a 15-year mortgage.
Your payments are predictable because, unlike with an adjustable-rate mortgage (ARM), your rate isn't going to change from year to year. Most years, the only things that might affect your monthly payment are any changes to your homeowners insurance or property taxes. The main disadvantage of 30-year fixed mortgage rates is the mortgage interest, both in the short and long term.
