- Enter your home's market value and your county's assessment ratio (many states assess at less than 100% of market value).
- Add your total millage or tax rate — find it on your current tax bill or county assessor site.
- Project annual increases to see your 5-, 10-, and 20-year tax trajectory with assessment caps applied.
How the Math Works
Worked example: a $350,000 home in a county assessing at 80% with a 1.4% effective rate: $350,000 × 0.80 = $280,000 assessed; × 1.4% = $3,920/year ($327/month — a real part of PITI that first-time buyers routinely underestimate). Effective rates swing wildly by state: New Jersey, Illinois, and Texas commonly exceed 1.8%–2.2% effective; Hawaii, Alabama, and Colorado run under 0.5%. On the same $350k home, that's the difference between $1,575 and $7,700 per year. Many states cap annual increases (California's Prop 13 caps assessed-value growth at 2%/yr until sale) — which is why two identical neighbors can pay very different taxes.
Property Tax FAQ
How do I find my property tax rate?
Your annual tax bill or county assessor website lists the millage. Effective rate = annual tax divided by market value - the number that compares fairly across states.
What is an assessment ratio?
The fraction of market value that is taxed - e.g., 80% means a $350k home is taxed as if worth $280k. Ratios vary from under 10% in some states to 100% in others.
Can I lower my property taxes?
Often yes: check for homestead exemptions, senior/veteran/disability exemptions you qualify for, and appeal assessments that rose faster than comparable sales. Appeals succeed at meaningful rates and cost little.
Why did my tax bill rise if the rate stayed flat?
Assessed value usually follows market value. A flat rate on a rising assessment still raises the bill - the projector shows this compounding over decades.
Are property taxes included in my mortgage payment?
Usually yes - lenders escrow taxes and insurance with each payment, then pay the county. Your monthly PITI includes 1/12 of the annual tax bill.
