How does this house payment calculator work?

This is a comprehensive calculator designed to help you determine the total monthly effort you will have to make to payout your mortgage and your own house related costs, thus it requires knowing the following details:

  • House price meaning the value you will pay for the property you buy.
  • Down payment which is the amount of money you have available for a one time deposit at the beginning of the real estate transaction. While the level required depends on the lender’s policy, it usually varies between 15 to 30% (most used level is 20%).
  • Term of the loan usually expressed in years or months. Most of the home mortgages are taken for a period which varies between 15 and 30 years, while the most common term is 25 years.
  • A constant interest rate level the lender offers.
  • A desired payment frequency which most probably will be monthly, but can be any value from the provided drop down list.
  • Annual property tax rate which is by default estimated to 1.2% but it is editable, so whenever the case it can be changed to any level.
  • Annual home insurance value you assume you will pay. For that you may contact a specialized broker and as for a quote for a similar property.
