Property taxes are the primary funding source for local governments, schools, and infrastructure. They are calculated by multiplying your property's assessed value by the local tax rate (also called the mill rate). The assessed value may differ from market value depending on your jurisdiction's assessment ratio. For example, if your home has a market value of $400,000, an assessment ratio of 80%, and a tax rate of 1.5%, your annual property tax would be $400,000 x 0.80 x 0.015 = $4,800. Understanding this calculation helps you budget for homeownership costs and evaluate properties in different tax jurisdictions.
The formula is Annual Tax = Assessed Value x Tax Rate. In jurisdictions using mill rates, one mill equals $1 per $1,000 of assessed value. A 25-mill rate means you pay $25 per $1,000, equivalent to a 2.5% tax rate. Some areas apply homestead exemptions that reduce your assessed value before calculating tax, further lowering the bill for primary residence owners.
Enter your property's assessed value (or market value with assessment ratio), the local tax rate as a percentage, and any applicable exemptions. The calculator shows your estimated annual property tax, monthly equivalent, and effective tax rate relative to market value. This helps you compare tax burdens across different locations when house shopping.
The US national average effective property tax rate is about 1.1%. However, rates vary dramatically: New Jersey averages 2.5%, while Hawaii averages 0.3%. Always check your specific county rate.
Yes. Taxes increase when assessed values rise (due to market appreciation or reassessment) or when local tax rates increase. Some states cap annual increases to protect homeowners from sudden jumps.
A homestead exemption reduces the taxable value of your primary residence. For example, a $50,000 exemption on a $300,000 home means you pay taxes on only $250,000. Eligibility and amounts vary by state.
