When to use this calculator
Use this property tax calculator to estimate annual and monthly property tax from a home value and tax rate. It is useful when comparing homes, building a housing budget, or checking whether a mortgage payment estimate leaves enough room for ownership costs.
Formula
Annual property tax = property value x tax rate
- Property value is the assessed or estimated value used for the calculation.
- Tax rate is entered as a percentage.
- Monthly property tax is the annual estimate divided by 12.
Worked example
For a $500,000 property with a 1.1% tax rate, the calculator estimates annual property tax and divides it into a monthly amount for budgeting.
Common mistakes
- Using market value when your local tax bill is based on assessed value.
- Forgetting that tax rates can change over time.
- Leaving property tax out of monthly affordability planning.
FAQs
Is property tax based on purchase price?
Not always. Many areas use an assessed value, which may differ from market price or purchase price.
Why convert annual tax to monthly?
Monthly estimates make it easier to compare property tax with mortgage payments and other housing costs.
Does this include special assessments?
No. Add local levies, special assessments or other charges separately if they apply.
