Practical tools for the two questions homeowners actually ask: am I being assessed fairly, and what would I pay somewhere else? Each one runs entirely in your browser — nothing you enter is sent to us or stored anywhere.
Works out a full monthly payment — principal, interest, taxes, insurance, PMI and HOA — with the property tax line calculated from your county’s real rates instead of the flat national guess most mortgage calculators apply to every house in the country.
When to use this: Use it when you are working out what a specific house would actually cost per month, particularly if you are comparing homes across county or state lines where the tax difference is large.
Compares your assessment notice and tax bill against what is typical for your county, and tells you whether a closer look might be worthwhile. It works backwards from your state’s statutory assessment ratio to show what your assessor appears to think your home is worth, then measures that against your own estimate.
When to use this: Use it when your assessment notice arrives and the number looks higher than you expected — before you spend time on a formal appeal.
Estimates what a move would do to your property tax bill using your own numbers — what your current home is worth and what you would actually pay for the next one — with each state’s exemptions and first-year caps applied to both sides.
When to use this: Use it when you have a specific move in mind and want the personalised figure. For browsing two areas against a single reference home, the County Comparison below is the better starting point.
Puts any two counties side by side and works out what the same home would cost you in each, applying real homestead exemptions, assessment caps, and equalization factors rather than a flat rate.
When to use this: Use it when you are exploring and want a like-for-like read on two areas. If you already know your own numbers, the Relocation Calculator above is the personalised version.
Every tool here works from county-level averages and published statutory rules. That makes them useful for orientation — for telling you whether something looks unusual and is worth investigating — and unsuitable as a substitute for your county’s own figures. None of them is an appraisal, a valuation, or tax advice, and none can tell you what your specific parcel is assessed at or why. For that, your county assessor or appraisal district is the only authority, and every county page on this site lists their phone number and website.
About this site's data and estimates. The Property Tax Almanac is an independent editorial reference. It is not affiliated with any government agency, tax assessor, or tax preparation service. The calculators and data on this site are informational and are not a substitute for advice from a qualified tax professional, attorney, or your official county assessor or appraisal district.
Accuracy, sources, and scope. Source years and review coverage vary. A record’s update date is not confirmation of its tax year. Reviewed guides identify their official sources and calculation limits; other records may have incomplete source documentation. See our methodology and review process.
How to use these estimates. Read the scope of each tool: it may use a representative district, a historical rate, or hypothetical inputs. County benchmarks are not a parcel-specific tax quote. Confirm the taxable value, taxing districts, applicable year, exemptions and additional charges with the responsible local office before relying on an estimate.
