How this calculator works
Most jurisdictions don't tax your property's full market value — they apply an assessment ratio first (often well under 100%) to get an "assessed value," then apply the local tax rate to that smaller number. Any exemption (like a homestead exemption) is subtracted before the rate is applied.
Worked example
A property worth $400,000 with a 50% assessment ratio has an assessed value of $200,000. At a 1.1% tax rate with no exemption, that's $200,000 × 1.1% = $2,200 in annual property tax — notably less than the $4,400 you'd get by (incorrectly) applying the rate to the full market value.
A note on "mill rates"
Some US jurisdictions quote property tax as a "mill rate" instead of a percentage — one mill is $1 of tax per $1,000 of assessed value. A mill rate of 11 is the same as a 1.1% tax rate (11 ÷ 1000 = 0.011). If your local assessor quotes a mill rate, divide it by 10 to get the equivalent percentage to enter here.
Why a low assessed value isn't a red flag
Seeing your assessed value well below your home's market value doesn't mean it's been undervalued for resale purposes — assessment ratios below 100% are standard practice in most jurisdictions by design, specifically to keep the taxable base smaller than market value.
Factoring this into a buy decision
Property tax is one of the ongoing costs of owning that renting doesn't have — if you're weighing a purchase, the Rent vs Buy Calculator compares the bigger financial picture, though it doesn't currently factor in property tax directly, so it's worth adding this estimate to that comparison manually.
Frequently Asked Questions
How is property tax calculated?
Most jurisdictions apply an assessment ratio to your property's market value to get an "assessed value" (often well under 100% of market value), then apply the local tax rate to that smaller number — any exemption is subtracted before the rate is applied.
Why is my assessed value lower than my property's market value?
Local assessors typically apply an assessment ratio below 100% by design — this is standard practice in most jurisdictions and doesn't mean your property is undervalued for sale purposes.
How often does property tax change?
Rates and assessments are set locally and can change annually or on a reassessment cycle that varies by jurisdiction — always confirm current figures with your local assessor's office rather than relying on a past estimate.
What is a mill rate?
Some US jurisdictions quote property tax as a mill rate instead of a percentage — one mill equals $1 of tax per $1,000 of assessed value. A mill rate of 11 is equivalent to a 1.1% tax rate. Divide a mill rate by 10 to get the equivalent percentage for this calculator.
Does this calculator account for exemptions like a homestead exemption?
Yes — enter any exemption amount you qualify for and it's subtracted from the assessed value before the tax rate is applied, matching how most jurisdictions calculate the final bill.
