Home Mortgage Calculator

A home mortgage payment is more than the principal-and-interest figure quoted by a lender. The amount paid each month can also include property taxes, homeowners insurance, and private mortgage insurance (PMI). The home mortgage calculator combines those recurring costs so that a buyer can compare a realistic monthly housing payment with their budget. Enter the purchase financing amount, the annual interest rate, the term in years, and any cash down payment. The financed principal is the amount after the down payment. For a fixed-rate mortgage, each scheduled principal-and-interest payment uses the standard amortization formula: monthly P&I = P × r × (1+r)^n / ((1+r)^n − 1), where P is principal, r is the monthly rate, and n is the number of months. Early payments are weighted heavily toward interest because interest is charged on the outstanding balance. Over time, a larger share of the same scheduled payment reduces principal. The displayed total interest shows the cost of that amortization schedule before optional taxes and insurance, which are not loan interest. Property tax and insurance are annual inputs converted to monthly amounts. Many lenders collect these amounts in an escrow account and pay the tax authority and insurer when bills are due. PMI is usually required when the down payment is below the lender's required equity threshold. Its rate varies by credit profile, loan type, and loan-to-value ratio; use the annual rate supplied by the lender or an estimate for planning. Use the result to explore trade-offs. A larger down payment reduces the financed balance and can remove PMI, while a shorter term generally raises the monthly payment but reduces total interest. The estimate does not include closing costs, HOA dues, maintenance, utilities, lender fees, changing taxes, or adjustable-rate changes. Confirm final payments and qualification requirements with a licensed lender before making a purchase decision. Revisit the assumptions after receiving a lender estimate, since escrow and insurance quotes commonly change.
