About this tool

Property tax is a three-step chain — market value, assessment ratio, millage rate — and this estimator walks the whole chain in the open. Enter your home's value, your jurisdiction's assessment ratio (many states tax only a fraction of market value), the combined millage rate from your last tax bill, and any homestead or other exemptions; the tool computes assessed value, taxable value, annual tax, the monthly amount to budget, and your effective rate. An optional cap projects next year's bill where states limit assessed-value increases. Because rates, ratios, exemptions and caps are set county by county, results can differ sharply across state lines even for identical homes — always confirm against your actual assessment notice. This is an educational estimate, not professional advice. All math runs locally in your browser and nothing is uploaded.
