🏡 Property Tax Estimator

Enter your home's assessed value and local property tax rate to estimate your annual and monthly property tax.

Assessed Value

Tax Rate (% per year)

Assessed value times the rate, split over twelve

Property tax is a percentage of assessed value, and the monthly figure is simply that bill divided by twelve because escrow collects it in equal instalments:

annual  = assessed value × (rate % / 100)
monthly = annual / 12
300,000 × 1.2% = $3,600 a year, or $300 a month

If your county quotes a mill rate instead, one mill is $1 per $1,000 of assessed value, so divide by 10 to get the percentage this box wants: 12 mills is 1.2%.

Assessed value is rarely the market value

Many states assess a fraction. South Carolina taxes owner occupied homes on 4% of market value and Georgia on 40%. Enter the figure on your assessment notice, not what the house would sell for.
Exemptions come off first. A $50,000 homestead exemption on this example leaves $250,000 taxable and cuts the bill to $3,000, saving $600 a year. Veteran, senior and disability exemptions stack on top.
Rates are nowhere near each other. Effective rates run from about 0.3% in Hawaii to over 2.2% in New Jersey - on this house, $900 a year against $6,600.

A browser cannot look up your parcel. It does not know your county rate, school and fire levies, special assessments such as Mello-Roos, a cap like California's 2% annual limit, or which exemptions you qualify for.

Frequently asked questions

What is the property tax on a $300,000 house?

At the 1.2% national ballpark, $3,600 a year or $300 a month. The same house costs about $900 in Hawaii and $6,600 in New Jersey, so the local rate matters more than the price.

How do I convert a mill rate to a percentage?

Divide by 10. A 25 mill levy is 2.5%; 8.5 mills is 0.85%. One mill is one dollar of tax for every $1,000 of assessed value.

Does property tax go up when my home value rises?

Usually, but not at once. Reassessment cycles run one to five years, several states cap annual increases, and districts often trim the rate when values jump so revenue stays flat.
