### Millage Rate - Overview, Sources, How To Calculate

Aug 29, 2020  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.
