Example Calculation

Let’s walk through a practical example:

• Assessed Property Value: $250,000
• Ad Valorem Tax Rate: 1.25%

Step 1: Convert the tax rate to a decimal → 1.25 ÷ 100 = 0.0125
Step 2: Multiply assessed value by rate → $250,000 × 0.0125 = $3,125

✅ Ad Valorem Tax = $3,125

So, the annual property tax on a $250,000 home at a 1.25% rate would be $3,125.
