This calculator calculates what a monthly mortgage payment should be given certain parameters of the mortgage and house. It supports escrow of taxes and insurance as well as a third-party servicer fee. If your mortgage does not have a third-party servicer fee, set that field to zero; and, if your mortgage is not subject to escrow, set the Property Taxes and Home Insurance Premium fields to zero as well.

This calculator assumes that monthly payments will start one month after issuance of the mortgage.
