Mortgage Calculator
Enter the loan terms. We'll calculate your monthly principal & interest, taxes, insurance, PMI if it applies, and the total cost over the life of the loan.
How this is calculated
This calculator uses the standard amortization formula for the principal & interest portion of your payment: your loan amount, interest rate, and term determine a fixed monthly payment where each payment covers that month's interest plus a bit of principal, with the principal share growing over time.
Property tax and homeowners insurance are optional — enter your best annual estimate and we'll convert it to a monthly amount and add it to your total payment.
PMI (private mortgage insurance) is required by most lenders when your down payment is below 20% of the home price. We estimate it at 0.5% of your loan amount per year — a common ballpark — and add it automatically whenever your down payment is under 20%. Actual PMI rates vary by lender, credit score, and loan type, typically ranging from about 0.5% to 1.5% annually.
This is an estimate for general information, not financial or lending advice. Talk to a lender for numbers you can actually rely on.
