Frequently asked questions
How is the monthly mortgage payment calculated?
Using the amortization formula M = P·r(1+r)ⁿ/((1+r)ⁿ-1), where P is the principal, r is the monthly rate, and n is the total number of payments.
What is included in a mortgage payment?
The base payment covers principal and interest (P&I). Your total payment also includes property taxes, homeowners insurance, and PMI if your down payment is below 20%.
How do extra payments reduce my mortgage?
Extra payments go directly to principal, reducing the balance on which interest accrues. Even a small monthly extra can save tens of thousands in interest over the life of the loan.
