Property Tax Calculator (US)

This property tax calculator estimates annual and monthly property tax from a home value and local tax rate. It is useful when comparing homes, planning escrow payments, or checking whether a purchase fits your total housing budget.

Property tax is usually set locally, so two homes with the same value can have very different annual bills. County, city, school district, exemptions, assessment rules, and special levies can all affect the final amount.

If a home is assessed at USD 350,000 and the local property tax rate is 1.2%, the estimated annual property tax is USD 4,200. Divided monthly, that is about USD 350 before any exemptions, caps, special assessments, or escrow adjustments.

This monthly view matters because buyers often focus on the mortgage payment alone. Property tax can materially change the true cost of owning a home, especially in high-tax counties.

Your bill may change when the property is reassessed, when local tax rates change, when exemptions expire, or when new levies are approved. A newly purchased home may also be reassessed closer to sale price, which can raise the bill after purchase.

For homebuyers, it is worth checking the local assessor or county tax office rather than relying only on the seller's old bill. The previous owner's exemptions or assessed value may not apply to you.

Use the calculator as a planning estimate, then verify the exact rules with the local authority. If taxes are paid through escrow, remember that lenders may adjust the monthly escrow amount when the actual bill changes.

When comparing homes, include property tax alongside mortgage, insurance, HOA fees, utilities, maintenance, and commuting costs. A lower-priced home in a higher-tax area is not always cheaper month to month.
