Use this calculator to estimate your annual property taxes based on your local millage rates.
How to use the millage calculator
1. Enter your property’s assessed value. This is usually lower than market value and can be found on your property tax bill or the county assessor’s website.
2. Find your millage rates. You can typically find these rates on your most recent property tax bill, your county tax assessor or treasurer’s website, or your local municipality or school district website.
3. Enter each local millage rate. Add the millage rates for the municipality (city or township), school district, county, and any other additional local taxes (if any).
4. View your estimated property taxes. The calculator will total your millage rates and estimate your annual real estate tax based on your assessment.
If you’re unsure about decimal placement, you can use the calculator’s decimal-moving feature to adjust the millage rate format.

How millage relates to property tax
Property taxes are typically calculated by multiplying your home’s assessed value by local tax rates. In many areas, those tax rates are expressed in mills (also called millage rates).
Your total property tax bill is usually made up of several millage rates combined — including rates from your municipality, school district, and county.
What is a mill?
A mill represents one-tenth of a cent in property tax for every dollar of assessed value.
- 1 mill = 0.001
- 10 mills = 0.010
- 100 mills = 0.100
Another way to think about it: One mill equals $1 in tax for every $1,000 of assessed property value.
So if your home has an assessed value of $100,000:
- 1 mill = $100 in property tax
- 10 mills = $1,000 in property tax
- 39 mills = $3,900 in property tax
Example calculation
| Taxing authority | Mills | Assessment | Property tax | ||
|---|---|---|---|---|---|
| Local | 0.0030 | x | 100,000 | = | $300.00 |
| School district | 0.0300 | x | 100,000 | = | $3,000.00 |
| County | 0.0060 | x | 100,000 | = | $600.00 |
| Total | 0.0390 | x | 100,000 | = | $3,900.00 |
