Frequently asked questions
How is the monthly mortgage payment calculated?+
The principal and interest payment uses the standard amortization formula: M = P × r(1+r)ⁿ ÷ ((1+r)ⁿ − 1), where P is the loan amount (price minus down payment), r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments (term in years × 12). Property tax, home insurance, and HOA dues are added on top for your total monthly payment.
What counts toward the total monthly payment?+
Principal and interest are the core loan payment. Many lenders also collect property tax and homeowner's insurance in an escrow account, and HOA dues are paid separately. This calculator lets you add all three so you see the full monthly cost, not just the loan payment.
Is this mortgage calculator accurate?+
The math is exact for a fixed-rate loan, but it's an estimate — it doesn't include PMI, closing costs, or lender-specific fees, and rates change daily. Use it to compare scenarios, then confirm the exact figures with your lender.
