Property Tax Estimator

Estimate your annual property tax based on your property's assessed value, assessment ratio, and local mill rate (tax rate per $1,000 of assessed value).

Market Value of Property ($)

Assessment Ratio (%)

Percentage of market value used for tax purposes (commonly 80–100%)

Mill Rate (mills)

1 mill = $1 per $1,000 of assessed value. U.S. average ≈ 10–20 mills.

Homestead / Other Exemption ($)

Amount subtracted from assessed value before tax is applied (e.g. homestead exemption)

#### Formula

Step 1 – Assessed Value Assessed Value = Market Value × (Assessment Ratio ÷ 100) Step 2 – Taxable Value Taxable Value = max(0, Assessed Value − Exemption) Step 3 – Annual Property Tax Annual Tax = Taxable Value × (Mill Rate ÷ 1,000) Step 4 – Monthly Equivalent Monthly Tax = Annual Tax ÷ 12 Step 5 – Effective Tax Rate Effective Rate = (Annual Tax ÷ Market Value) × 100

#### Assumptions & References

Mill rate (also called millage rate) is the tax rate expressed as dollars per $1,000 of assessed value. The U.S. national average is roughly 10–20 mills, but rates vary widely by county and municipality.
Assessment ratio is the fraction of market value used as the tax base. Many jurisdictions assess at 100% of market value; others use 80%, 50%, or other ratios set by state law.
Homestead exemption reduces the taxable assessed value for owner-occupied primary residences. Common amounts range from $5,000 to $50,000+ depending on the state.
