What is this tool?
Property tax is a recurring tax levied by local governments on real estate, based on the value of the property. It is one of the largest ongoing costs of homeownership, and unlike a mortgage payment it never goes away — you pay it for as long as you own the property. Property taxes fund local services such as public schools, police and fire departments, road maintenance and libraries.
The amount you pay depends on two factors: the assessed value of your property (which is determined by the local tax assessor and may differ from the market value) and the local tax rate (often expressed as a percentage of assessed value or as a rate per thousand dollars of value, sometimes called a mill rate). Tax rates vary enormously between jurisdictions, so two identical homes in different areas can have very different tax bills.
This property tax calculator lets you enter the assessed value and the annual tax rate as a percentage. It computes the annual property tax, the equivalent monthly amount (useful for budgeting your total housing payment), and the effective tax rate. Everything runs locally in your browser.How it works
The annual property tax is calculated as Annual Tax = Assessed Value × (Tax Rate / 100). For example, a home assessed at 350,000 dollars in an area with a 1.2 percent tax rate has an annual property tax of 350,000 × 0.012 = 4,200 dollars. The monthly amount is simply the annual tax divided by 12: 4,200 / 12 = 350 dollars per month.
The effective tax rate expresses the annual tax as a percentage of the assessed value, which is useful for comparing the tax burden across different properties or jurisdictions. If you enter a tax rate in mills (1 mill = 0.001 dollars per dollar of value = 0.1 percent), simply convert it to a percentage by dividing by 10 before entering it (20 mills = 2.0 percent). The calculator validates that both the assessed value and the rate are positive numbers before computing the result.How to use

Frequently Asked Questions
What is the difference between assessed value and market value?
The assessed value is the value assigned by the local tax assessor for tax purposes, while the market value is what the property would sell for today. Assessed values are typically updated on a regular schedule (annually or every few years) and may lag behind market changes, so they can be higher or lower than the current market value.
How do I convert a mill rate to a percentage?
One mill equals one dollar of tax per thousand dollars of assessed value, which is equivalent to 0.1 percent. To convert mills to a percentage, divide by 10: a rate of 25 mills equals 2.5 percent. Enter the percentage value in the calculator’s rate field.
Why do property taxes vary so much between areas?
Property tax rates are set locally and depend on the funding needs of the community, the total tax base, the level of services provided and state-level caps or limitations. Areas with high home values may have lower percentage rates but still collect large amounts in absolute dollars, while areas with lower values may need higher rates to fund the same services.
Can I appeal my property tax assessment?
Yes, in most jurisdictions you have the right to appeal if you believe your assessed value is too high. You typically need to provide evidence such as recent comparable sales or an independent appraisal. Successful appeals can lower your assessed value and reduce your annual tax bill, so it is worth checking whether your assessment is in line with the market.

Tips & Advice
Property taxes are often the second-largest cost of homeownership after the mortgage payment, so always factor them into your housing budget before buying. When comparing homes in different areas, look up the actual tax bills rather than relying on listing estimates, which can be based on outdated assessments or previous (lower) values. Some states and municipalities offer homestead exemptions, senior-citizen discounts or other reductions that can significantly lower your effective tax rate, so check with your local tax office for available programs. If you are buying a newly built home, be aware that the current assessment may be based on the vacant land value and could jump dramatically once the home is completed — budget for the higher amount to avoid surprises. Property taxes generally rise over time as assessments increase and local governments adjust rates, so when planning long-term housing costs, assume a modest annual increase of 2–3 percent on top of today’s figure. Finally, remember that property taxes are typically deductible on your income taxes if you itemise deductions (subject to the SALT cap of 10,000 dollars in the US), which can partly offset the cost.
