How Property Tax Is Calculated
Assessed Value = Property Value × (Assessment Ratio / 100)
Taxable Value = Assessed Value − Exemptions
Annual Property Tax = Taxable Value × (Tax Rate / 100)
Monthly Property Tax = Annual Property Tax ÷ 12
Effective Tax Rate = (Annual Property Tax ÷ Property Value) × 100
