Property Tax by State Formula

This calculator applies each state's average effective property tax rate (annual property tax as a percentage of home value) to your home's value, after subtracting any homestead exemption, to estimate your annual and monthly property tax bill.

Taxable Value = max(0, Home Value − Homestead Exemption)
Annual Property Tax = Taxable Value × (Effective Tax Rate % ÷ 100)
Monthly Property Tax = Annual Property Tax ÷ 12

Effective tax rates represent the average annual property tax paid as a percentage of a home's market value across an entire state, and can vary significantly by county and municipality within that state. A homestead exemption reduces the taxable value of a primary residence and is offered by many (but not all) states and localities — the amount and eligibility rules vary widely, so check with your local tax assessor for your exact exemption.
