Estimates are illustrative, not lender approval. PMI depends on your loan and lender; maintenance is a reserve rather than a fixed bill. Taxes, insurance and rates may change. Excludes utilities and moving costs.

How this estimate is calculated

Loan principal is the home price less the percentage down payment. Principal and interest assumes a fixed annual interest rate, equal monthly payments and full repayment over the entered term. Use the interest rate, not APR. For monthly rate r and n monthly payments, payment = principal × r ÷ [1 − (1 + r)−n]; at zero interest, payment = principal ÷ n. A stable equivalent is used for very small rates.

For the illustrative default $500,000 home with 20% down, a 6.5% rate and 30-year term, the $400,000 loan has approximately $2,528 monthly principal and interest. Adding the displayed tax, insurance and maintenance assumptions gives about $3,678 per month. Down payment plus the entered 3% closing-cost allowance is $115,000. These are examples, not current quotes.

The comparison with gross income includes the entered maintenance reserve and other debts; it is not a lender debt-to-income calculation or an approval threshold. The model does not calculate tax deductions, rate changes, extra principal payments, refinancing or lender-specific fees. Adjust the assumptions to the actual offer, and review the official Loan Estimate linked below. Your inputs stay in your browser.
