Tax Rate Calculator

The calculator floors the property-tax revenue needed at zero rather than letting it go negative, so the Required Mill Rate becomes 0 once Non-Tax Revenue meets or exceeds the Total Budget Needed. Beyond that point, further increases in Non-Tax Revenue have no additional effect on the mill rate since there's nothing left for property tax to cover.

The mill rate is the tax revenue needed divided by the total assessed value, then scaled to a per-$1,000 figure. With the dollar amount needed held fixed, spreading it across a larger assessed value base means each $1,000 of property has to contribute less, so the rate needed to hit the same revenue target goes down.

They represent the same underlying rate, just displayed two ways: Required Mill Rate is the raw mill figure to three decimal places, and Tax Per $1,000 Value shows that identical number formatted as a dollar amount. Neither one changes independently of the other -- moving any input moves both together.

No. It applies the calculated mill rate to a fixed illustrative $250,000 assessed value to give a concrete reference point, not an estimate for a particular property. Actual bills depend on that property's own assessed value, and in most places on additional mill rates set separately by overlapping taxing jurisdictions like school districts and counties.

No. It assumes the full assessed value figure you enter is fully taxable at the calculated rate. Real jurisdictions often apply homestead exemptions, senior or veteran exemptions, or caps that limit how fast assessed value can rise, all of which would reduce actual bills below what this simplified calculation shows.
