Frequently Asked Questions
Your monthly mortgage payment is calculated using the standard amortization formula: M = P[r(1+r)^n] / [(1+r)^n - 1], where P is the loan principal, r is the monthly interest rate, and n is the number of monthly payments. Our calculator also adds property tax, insurance, PMI (if applicable), and HOA fees to give you the complete monthly cost.
PMI (Private Mortgage Insurance) is required when your down payment is less than 20% of the home price. PMI typically costs 0.5% to 1% of the loan amount annually. It protects the lender — not you — if you default on the loan. Once you reach 20% equity in your home, you can request to have PMI removed. Learn more about PMI →

Yes – our calculator uses the exact same standard amortization formula used by banks and lenders. The results are estimates because your actual payment may vary based on your specific lender's terms, exact closing date, and local tax rates. Always verify with your lender before making a final decision.
