    The true cost of owning a home

    When people say "my mortgage", they often mean just the loan payment — principal and interest. But owning a home costs more each month. Property tax, home insurance, mortgage insurance and any HOA fee all add up, and lenders usually collect them alongside the loan. This calculator shows both the loan payment and the all-in monthly cost, so there are no surprises.

    Example. A 300,000 home with 60,000 down (20%) means a 240,000 loan. At 6% over 30 years the principal and interest come to about 1,438.92 a month. Add your own tax, insurance and any HOA to see the full monthly figure.

    Down payment matters twice

    A bigger down payment lowers the loan, so the monthly payment and the total interest fall. It can also push you past the point where PMI is required, removing another monthly cost. Below about 20% down, many lenders add PMI until you build enough equity.

    Shortening the loan with extra payments

    Any extra principal each month reduces the balance faster and saves interest, just like an ordinary loan. The extra only affects the loan part — taxes, insurance and HOA are separate ongoing costs. For a plain loan without housing costs, see the Amortization Calculator.

    Frequently asked questions

    What is included in the monthly payment?

    The loan part is principal and interest (P&I). On top of that, owning a home usually costs property tax, home insurance, mortgage insurance (PMI) if your down payment is small, and sometimes an HOA or condo fee. The all-in figure adds them all together.

    How do the down payment amount and percentage work together?

    They stay in sync. Type an amount and the percentage updates; type a percentage and the amount updates. The loan is the home price minus the down payment.

    What is PMI?

    Private mortgage insurance is often required when the down payment is below about 20%. Here it is estimated as a yearly percentage of the loan, divided by 12. Real PMI rules, and when it can be removed, vary by lender and country, so treat it as an estimate.

    Is this a lender quote?

    No. It is an estimate to help you plan. Your lender's figures can differ because of rounding, fees, escrow rules, exact tax and insurance amounts, and local regulations.

    How is this different from the EMI calculator?

    The loan maths is the same, but a mortgage has extra monthly costs — tax, insurance, PMI and HOA — which this tool adds in to show the true cost of owning the home.
