Property Tax Estimator — Annual & Monthly Tax Calculator

Estimate annual property taxes by entering the assessed value and local tax rate (mill rate). The result shows the annual and monthly tax burden, the effective rate as a percentage of assessed value, and an affordability rating based on typical residential tax ranges. Because tax rates and assessment ratios vary significantly by county and state, this is a planning tool — verify with your local assessor's office for precise figures.

Frequently Asked Questions

How is property tax calculated?
Property tax equals the assessed value multiplied by the tax rate (mill rate). The assessed value may differ from market value — some jurisdictions assess at 100% of market value, others at 80% or less. The tax rate is set by local government and expressed as a dollar amount per $1,000 of assessed value.
Where do I find my local tax rate?
Your county assessor's or treasurer's website is the most reliable source. You can also look at recent tax bills for comparable properties in the area, which real estate listing platforms like Zillow and Redfin often display alongside listing details.
Can I appeal my property tax assessment?
Yes. Most jurisdictions allow homeowners to appeal an assessment they believe is too high, typically within 30–90 days of receiving the assessment notice. You'll need to provide evidence of the property's actual value — comparable sales, a private appraisal, or documentation of defects that affect value.
