Millage Rate Overview, Sources, How To Calculate
2020-8-29 By definition, one mill is equivalent to $1 owed per $1,000 (one-thousandth of a dollar). Millage rates are mathematically expressed as %0. It means that 1%0 represents one part per thousandth and can also be expressed as 0.1%. Thus, 45 mills are equal to $45 per every $1,000 of the estimated property value.
