Property tax is a local, recurring charge on real estate. The county assessor assigns your home an assessed value, then the total of all your local tax rates (county, school district, city, special districts) is applied to it. The math is simple: annual tax = (assessed value − homestead exemption) × tax rate. The monthly figure is that amount divided by 12, which is useful for budgeting since most lenders and many states collect in monthly installments.
Property tax is the assessed value of your home multiplied by the local tax rate. First, the county assessor assigns your home an assessed value (which may differ from the sale price). Then the local tax rate — set by your county, school district and other taxing authorities — is applied: annual tax = (assessed value − exemptions) × tax rate. This tool does exactly that, then divides by 12 for a monthly figure.
The national average effective rate is around 1.0–1.2% of the home's value per year. It varies widely by state and county: places like Texas, Louisiana and New Jersey commonly exceed 2%, while states such as Hawaii and Alabama average well under 0.6%. The rate you pay is the sum of all the taxing districts that cover your address.
A homestead exemption is a deduction from your home's assessed value that lowers the portion of the value subject to property tax. Rules vary by state: Florida allows $50,000, Texas a flat $100,000 for school districts, and some states cap the annual increase in assessed value instead. Generally you must live in the home as your primary residence and file an application with the county.
Assessed value is the assessor's estimate of your home's market value, updated on a set schedule (annually in some states, less often in others). It can be higher or lower than your purchase price depending on local market movement, and in some states it is artificially limited by assessment caps that prevent it from jumping too fast after a sale.
It is a reasonable estimate, not an official figure. Real bills depend on your county's exact assessed value, all applicable district rates, exemption rules and any billing adjustments. Check your local tax assessor's website for the precise numbers — but this tool gets you within a useful ballpark for budgeting and comparisons.
