How to calculate property tax

Property tax is the taxable value of your home times the combined tax rate of every local government that taxes it. Taxable value is the market value times the state's assessment ratio, minus any exemptions; each county, city, school district and special district then applies its own rate.

Tax = (Market value × assessment ratio − exemptions) × tax rate

The pieces differ by state, which is why a calculator built on one national average gets most bills wrong:

Property tax by county: the same home in each county

A $350,000 home with no exemptions owes very different amounts depending on the county and taxing area. The table runs the calculator for the first area listed in each county, next to the county's median bill from Census data.[1][2]

Effective property tax rate

The effective rate is your annual tax divided by your home's market value, the fairest way to compare places. Nationally it was about 0.89% in 2024; the state-by-state ranking is on property tax rates by state. Two homes with the same nominal rate can have very different effective rates because of caps (such as California's Prop 13), assessment ratios and exemptions such as the Texas homestead exemption.

What the calculator does not include

  • Special assessments and fixed charges (sewer, lighting, mello-roos, solid waste) printed on some bills.
  • Caps that depend on your property's history (Texas 10% homestead cap, California Prop 13 base year, Arizona limited value). County pages explain each and let you enter your capped value.
  • Tax ceilings and freezes for seniors, which keep some school or county taxes at a past level.

When the bill arrives, check the dates on property tax due dates and the senior programs on property tax exemptions for seniors; what a missed exemption costs in each county is on homestead exemption savings. If the value on your notice looks too high, the free property tax assessment appeal calculator turns comparable sales into a fair-value estimate, your possible savings and a printable summary.

Frequently asked questions

How do I calculate property tax?

Multiply the market value by your state's assessment ratio, subtract exemptions, and multiply by the combined tax rate. Example: a $300,000 Texas home with a $140,000 school homestead exemption pays the school rate on $160,000 and the other rates on the value left after their own exemptions.

What is a good property tax estimator?

One that uses your county's adopted rates by taxing unit and your exemptions, not a state average. Pick your county above; every rate is linked to the office that adopted it.

What is the average property tax in the U.S.?

The median homeowner paid $3,211 in 2024 on a $360,600 median home (Census ACS).
