I'm confused about your question. I think I need more information to understand what you're trying to accomplish. Are you trying to figure out what a monthly payment would be on a mortgage? if so, then you'll need the amount of the loan, the interest rate, and the length of term on the mortgage.
Amount of loan $100,000
Interest rate 3%
Term of Loan 20 years
Using a mortgage calculator the monthly payment would be
This is without Insurance and Taxes, so if you don't have escrows included in your mortgage, then this is all your Mortgage payment would be, but if you have the Insurance and Taxes escrowed (included in your monthly payment) then, that will be added to the $555. Does this make sense?
