How to Calculate the Mill Rate

Step 3. Take the newly converted rate (.02) and multiply it by your property's assessed value to determine the amount of tax owed for the year. For example, an owner of property assessed at $650,000 would find the property tax amount by first multiplying the mill rate of 20 by .001 (equaling .02) and then multiplying .02 by $650,000 to get
