Why Property Tax Calculation Matters

Property tax is a major expense for homeowners and investors. Accurately estimating it helps with budgeting, mortgage planning, and investment analysis. This calculator gives you a quick, reliable estimate using the standard formula.

Formula Used

Annual Property Tax = Home Value × (Tax Rate / 100)
Monthly Tax = Annual Tax / 12
