Property Tax Calculator
Estimate annual property tax from property value, assessment ratio, exemptions, and your local rate.
Use your local assessment rules and tax rate
This estimator does not guess a rate from a country or state. Use the assessed value, assessment ratio, exemptions, and annual rate from your local assessor or latest tax notice.
This selection only labels entered values and results. It does not convert amounts or use exchange rates.
If you already know the assessed value, enter it here and leave the assessment ratio at 100%.
Assessed value = property value × assessment ratio.
Enter only an exemption that reduces assessed value in your jurisdiction.

How This Property Tax Calculator Works
This jurisdiction-neutral estimator uses the assessment ratio, exemption, and annual rate you enter. It does not guess current state, county, municipal, or national rates.
Formula and Calculation
The core formula used by this property tax calculator is: Taxable assessed value = (property value x assessment ratio) - eligible assessed-value exemption. Annual property tax = taxable assessed value x local tax rate.
The tool converts either a percentage or millage rate to a decimal, applies it to taxable assessed value, and shows annual, quarterly, and monthly budgeting equivalents.
For a property worth $300,000, a 100% assessment ratio and 1.2% rate produce an estimated annual tax of $3,600 before any additional local charges.
How to Use This Calculator
- Enter market value, or enter assessed value and keep the ratio at 100%.
- Enter the assessment ratio shown by your local authority.
- Subtract only an eligible exemption that reduces assessed value.
- Enter the current local rate as a percentage or mills and review the estimate.
