What this calculator does

Estimate annual and periodic property tax from assessed value, exemptions, and either a percent rate or millage rate.

How it works

The calculator evaluates taxable value = max(assessed value − exemptions, 0); tax = taxable value × rate. Inputs are checked before calculation, and invalid values such as zero denominators or out-of-range selections produce a clear error instead of a misleading result.
