A millage rate (also called mill rate or mill levy) is the dollar amount of tax per $1,000 of a property's assessed value. 1 mill = $1 of tax per $1,000.
Example: A property with an assessed value of $200,000 and a millage rate of 10 mills would owe $2,000 per year in property taxes (before exemptions).
Formula: Annual Tax = (Assessed Value − Exemptions) × Mill Rate ÷ 1,000

A millage rate (or mill rate) is the amount of property tax levied per $1,000 of assessed value. 1 mill = $1 of tax per $1,000. So a 10-mill rate on a $200,000 property equals $2,000 per year in property taxes.
Check your county assessor or tax collector's website, or look at your property tax bill — it usually lists the total mills or mill levy. You can also call your local tax office. Many counties publish their mill rates annually.
Market value is what your home would sell for on the open market. Assessed value is the value assigned by your local government for tax purposes — typically 50–100% of market value depending on your state's assessment ratio.
Use this formula: Tax = (Assessed Value − Exemptions) × Mill Rate ÷ 1,000
Example: ($300,000 − $25,000) × 15 ÷ 1,000 = $4,125 per year. Our calculator does this automatically.
A homestead exemption reduces the assessed value of your primary residence for property tax purposes. Common exemption amounts range from $25,000 to $50,000 depending on the state, lowering your overall tax bill.
