Your personalized analysis

Summary

Your property tax is about $4,400 a year

At a 1.10% rate on $400,000 of taxable value, that's $4,400 annually, or $367 a month. Most lenders collect this in your escrow account as part of your mortgage payment. Your effective rate on the full $400,000 value is 1.10%.

Recommendation

Check whether you qualify for an exemption

Many areas offer a homestead exemption that removes part of your home's value from taxation, plus exemptions for seniors, veterans and people with disabilities. These usually require a one-time application and are frequently missed. Even a modest exemption can save hundreds a year — worth a call to your county assessor.

Watch out

Rates and assessments vary enormously by location

Property tax rates range from under 0.3% to over 2.2% across US states, and assessments can rise year to year. If your assessment jumps or seems high relative to comparable homes, you can usually appeal it — a meaningful share of appeals succeed. This estimate uses the rate you entered; confirm your actual rate with your county, since local rates aren't something to guess at.

Property tax is one part of your monthly housing cost. The mortgage calculator combines it with principal, interest, insurance and PMI for your complete payment.

Summary

Your property tax is about $4,900 a year

At a 1.40% rate on $350,000 of taxable value (after a $50,000 exemption), that's $4,900 annually, or $408 a month. Most lenders collect this in your escrow account as part of your mortgage payment. Your effective rate on the full $400,000 value is 1.22%.

Recommendation

Your exemption saves $700 a year

The $50,000 homestead exemption removes that value from taxation, saving you about $700 annually at your rate. Homestead and other exemptions (senior, veteran, disability) are often not automatic — you usually have to apply once. If you haven't, it's worth checking what your county offers.

Watch out

Rates and assessments vary enormously by location

Property tax rates range from under 0.3% to over 2.2% across US states, and assessments can rise year to year. If your assessment jumps or seems high relative to comparable homes, you can usually appeal it — a meaningful share of appeals succeed. This estimate uses the rate you entered; confirm your actual rate with your county, since local rates aren't something to guess at.

The basics

How property tax is calculated

Property tax is your home's taxable value multiplied by a local tax rate set by your county, city, school district and other local authorities combined. The taxable value is usually the assessed value — which may differ from market value — minus any exemptions you qualify for. Because the rate is local, two identical homes in different towns can have very different tax bills.

This calculator uses the rate you enter, because local property tax rates aren't something to estimate from a formula — they're set locally and vary widely. Your actual rate is on your tax bill or available from your county assessor. The US average is around 1.1%, but rates range from under 0.3% to over 2.2% depending on the state and locality.

  • Property tax = taxable value × local rate
  • Taxable value = assessed value − exemptions
  • Rates are set locally and vary widely
  • Usually collected monthly in your mortgage escrow

Going deeper

Exemptions and appeals

Most areas offer exemptions that reduce your taxable value: a homestead exemption for your primary residence is the most common, with additional exemptions for seniors, veterans and people with disabilities. These usually require a one-time application and are surprisingly often missed — claiming one you're entitled to can save hundreds of dollars a year, every year.

If your assessment rises sharply or looks high compared to similar nearby homes, you can appeal it. The process varies by county but generally involves submitting comparable sales or an independent appraisal. A meaningful share of appeals succeed in lowering the assessment, and because property tax recurs annually, a successful appeal keeps paying off for years.

Common mistakes

  1. 1

    Guessing the tax rate

    Property tax rates are local and vary widely. Use your actual rate from your tax bill, not a national average, for an accurate figure.

  2. 2

    Missing exemptions

    Homestead and other exemptions often require a one-time application and are frequently missed, leaving hundreds a year on the table.

  3. 3

    Not appealing a high assessment

    If your assessment jumps or exceeds comparable homes, an appeal can lower it — and the savings recur every year.

  4. 4

    Forgetting taxes rise over time

    Assessments and rates increase. Budgeting today's tax bill for the long term understates future housing costs.

  5. 5

    Ignoring property tax when buying

    A low price in a high-tax area can cost more monthly than a higher price in a low-tax area. Factor tax into affordability.

Common questions

How much is property tax?

It's your home's taxable value times a local rate, which varies enormously — from under 0.3% to over 2.2% across US states, averaging about 1.1%. On a $400,000 home at 1.1%, that's roughly $4,400 a year, or $367 a month. Enter your home value and local rate above for an estimate; find your actual rate on your tax bill.

How is property tax calculated?

Multiply your home's taxable value (assessed value minus any exemptions) by your combined local tax rate. The rate is set by your county, city, school district and other authorities together. Because rates are local, this calculator asks you to enter yours rather than guessing — it's on your tax bill or from your county assessor.

What is a homestead exemption?

A homestead exemption reduces the taxable value of your primary residence, lowering your property tax. The amount and rules vary by area — some exempt a fixed dollar amount, others a percentage. It usually requires a one-time application and is often missed. Additional exemptions exist for seniors, veterans and people with disabilities.

How can I lower my property tax?

Claim every exemption you qualify for (homestead, senior, veteran, disability), and appeal your assessment if it seems high relative to comparable homes. A successful appeal lowers the assessed value, and because property tax recurs every year, the savings compound. Both steps are underused ways to reduce a recurring cost.

Is property tax included in my mortgage payment?

Usually, yes. Most lenders collect property tax monthly in an escrow account as part of your mortgage payment, then pay the county on your behalf when it's due. That's why your monthly payment (PITI) is higher than principal and interest alone. If you own outright, you pay the county directly, typically once or twice a year.
