The Short Answer

Multiply your property's assessed value by the local tax rate and you have your annual bill; divide that by twelve and you have the monthly escrow figure a lender will collect. The two variables that actually move that number are your state's typical rate, anywhere from well under 1% to over 2% depending on where you live, and your local assessment ratio, which decides how much of the home's market value is actually taxable.

How Is Property Tax Calculated

Start with the property's market value and apply the assessment ratio, often 100% but lower in some states, to get assessed value. Multiply assessed value by the tax rate, either a state typical rate from the table below or a custom county rate you enter, to get the annual bill. Divide by twelve for the monthly escrow figure, and compare the effective rate (annual tax over market value) against the roughly 1.1% national average to see whether the location runs hot or cold on tax.

Use your local rate: property tax varies widely by county, so the custom-rate field gives the most accurate result once you know your actual bill.

Why your tax bill is not just price times rate

Two things sit between your home's value and your tax bill: the assessment ratio, the share of market value your county actually taxes, and the local millage rate. A $350,000 home assessed at 100% in a 2.27% state pays far more than the same home in a 0.67% state. Property tax is one of the biggest geographic cost swings in real estate, often larger than the difference in insurance or maintenance between two states.

Plan for the escrow line

Most lenders collect property tax monthly and pay the county for you, so the bill shows up as a chunk of your total mortgage payment rather than a once-a-year surprise. The monthly escrow figure here is what to actually budget for. Rates change from year to year and vary by county even within the same state, so use the custom-rate field once you know your exact local number from an assessor's notice or closing disclosure.
