Frequently Asked Questions

How is the monthly payment calculated?+
We use the standard amortization formula: M = P[r(1+r)^n] / [(1+r)^n - 1], where P is the principal, r is the monthly interest rate, and n is the number of payments.
Does this include taxes and insurance?+
No, this calculates principal and interest (P&I) only. Your actual monthly payment for a mortgage would typically also include property taxes, homeowner's insurance, and potentially PMI.
What is amortization?+
Amortization is the process of spreading loan payments over time. In early payments, more goes toward interest. As the loan matures, more goes toward principal - this is why extra payments early on save the most money.
