About This Tool
Property taxes fund municipal services, public school districts, and county infrastructure through ad valorem assessments on real estate.
### Mathematical Formula Property tax liability is calculated across four sequential steps: 1. **Assessed Value:** Home Market Value * Assessment Ratio. 2. **Taxable Assessed Value:** Math.max(0, Assessed Value - Homestead Exemption). 3. **Annual Property Tax:** Taxable Value * (Property Tax Rate / 100). 4. **Monthly Tax Escrow:** Annual Property Tax / 12.
### Worked Numeric Example A home in Texas has an estimated market value of $450,000 in a jurisdiction assessing at 100% of market value with a $40,000 general homestead exemption and a 1.80% combined millage rate: 1. Assessed Value: $450,000 * 1.00 = $450,000. 2. Taxable Value: $450,000 - $40,000 = $410,000. 3. Annual Property Tax: $410,000 * 0.0180 = $7,380.00. 4. Monthly Escrow Payment: $7,380.00 / 12 = $615.00 per month. 5. Effective Tax Rate on Market Value: ($7,380 / $450,000) * 100 = 1.64%. 6. Five-Year Cumulative Projection (modeling 2% annual appraisal inflation): $38,745.00.

Frequently Asked Questions
How does an assessment ratio differ from market value?
Market value represents what a buyer would pay for your home. The assessment ratio is the percentage of market value that local taxing authorities use to determine your official tax bill.
What is a homestead exemption and how does it reduce property tax?
A homestead exemption shields a specific dollar amount or percentage of a primary residence value from school and county property taxation, lowering your taxable assessed base.
Is property valuation or real estate data stored on remote servers?
No. All calculations run strictly in client-side browser memory with zero network data transmission or cloud storage.
