Calculate your monthly home payment with principal, interest, taxes, insurance, and PMI
A mortgage calculator estimates your monthly home payment based on the loan amount, interest rate, and term — plus the recurring costs that lenders include in the full payment: property taxes, home insurance, private mortgage insurance (PMI), and HOA fees. The total monthly figure tells you what the home will actually cost each month, not just the principal and interest.
PITI stands for Principal, Interest, Taxes, and Insurance — the four core components of a typical mortgage payment. Lenders use total PITI to evaluate affordability (the 28% rule: PITI should not exceed 28% of gross monthly income). When down payment is below 20%, PMI is added on top — typically 0.3% to 1.5% of the loan amount per year.

PITI stands for Principal, Interest, Taxes, and Insurance — the four components of a typical monthly mortgage payment.
PMI (Private Mortgage Insurance) protects the lender if you stop paying. It is required when your down payment is less than 20%. Once your loan-to-value ratio drops below 80%, PMI is typically removed.
P&I uses the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the loan amount, r is the monthly rate, n is the number of months. Taxes, insurance, PMI, and HOA are added monthly.

It uses the standard formula used by lenders and is mathematically accurate. Real estimates also include closing costs, escrow fees, and lender charges. Always consult a licensed mortgage professional.
