Frequently Asked Questions About Mortgage Calculator
What does the monthly payment include?
It shows principal and interest from the loan, plus monthly property tax and home insurance if you enter yearly amounts (often called PITI). The headline figure is your full estimated monthly housing payment.
How is the principal and interest calculated?
It uses the standard amortization formula on the loan amount (home price minus down payment), the monthly interest rate, and the number of monthly payments. This is the same math lenders use for a fixed-rate mortgage.
Does it include PMI or HOA fees?
No. It covers principal, interest, property tax, and insurance. Add private mortgage insurance (PMI), HOA dues, or other costs separately for a complete budget.
