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

In pilot-scale mills, where it is possible to directly measure these losses it is found that proportionately they are relatively high and can be as much as 20% of the gross power. However, in full scale mills these losses are proportionately much smaller. A reasonable working estimate to use in the case of gear-and-pinion drives would be 6-7%
