How this works: The principal and interest payment uses the standard mortgage formula. The property tax uses the 2025 total millage for each county’s main unincorporated tax area, with the home price as its taxable value. With homestead, the first $25,000 is exempt from all taxes and up to another $25,000 is exempt from non-school taxes. City rates run higher, often 17 to 20 mills, so check yours with the county property appraiser.

Estimates: The insurance figure is the average homeowners premium with wind coverage for each county, from the Florida Office of Insurance Regulation (figures as of March 31, 2026). Your quote will depend on the home, the insurer, and your deductible. PMI is estimated at $50 a month per $100,000 borrowed, the middle of the $30 to $70 range Freddie Mac gives, and only applies with less than 20% down on a conventional loan.

Not included: Non-ad valorem assessments on the tax bill (trash, stormwater, and similar), the discount for paying property taxes early, maintenance, and utilities. The default rate is the Freddie Mac 30-year average as of October 1, 2026. For one-time costs at closing, use the closing cost calculator.

How to use the calculator

Start by picking the county. The calculator fills in that county’s property tax rate and its average homeowners insurance premium. Then enter the home price, your down payment, and your interest rate. The default rate is the national 30-year average as of October 1, 2026, so put in the rate your lender actually quoted if you have one. Choose “Yes, homestead” if the home will be your primary residence. That takes up to $50,000 off its taxable value. A second home or rental pays tax on the full value, so the tax line goes up noticeably.

The two pre-filled boxes are starting points, so change them whenever you have better numbers. Inside city limits, the property tax rate is usually higher than the county rate shown here. Look up the rate for the exact address on the county property appraiser’s website and type it in. Once you have a real insurance quote, replace the county average with it. If the home is in an HOA or a CDD, add the monthly fees, and add flood insurance if the lender requires it or you plan to carry it.

The results are split into two groups. The “Calculated” lines come straight from fixed formulas and published tax rates, so they’re accurate for the numbers you entered. The “Estimates” lines depend on the insurer, the lender, or the community. As an example, a $400,000 homestead in unincorporated Orange County with 20% down at 7.28% comes to about $3,090 a month: $2,190 in principal and interest, $599 in property tax, and $301 for insurance. For the one-time costs at closing, use the closing cost calculator. For each county’s full numbers, see what it costs to buy a home in Central Florida.

Frequently Asked Questions

At each county’s median price with 20% down and a 7.28% rate, the monthly cost including property tax and average insurance runs from about $2,270 in Polk to $3,160 in Orange. HOA or CDD fees, flood insurance, and PMI with less than 20% down add to that.

In unincorporated areas, 2025 rates run from about 12.4 mills in Brevard to 17.4 mills in Volusia, meaning $12.40 to $17.40 per $1,000 of taxable value. City rates are usually higher, often 17 to 20 mills. Your county property appraiser can give the exact rate for an address.

It takes up to $50,000 off a home’s taxable value: the first $25,000 for all taxes and up to another $25,000 for non-school taxes. On a $400,000 home in unincorporated Orange County, that saves about $640 a year, or $54 a month. The Save Our Homes cap on later increases saves more over time.

Freddie Mac puts private mortgage insurance at about $30 to $70 a month for every $100,000 borrowed. It applies to conventional loans with less than 20% down and drops off automatically when the loan balance is scheduled to reach 78% of the home’s original value.

The calculator uses the purchase price as taxable value and each county’s main unincorporated rate. Your bill may differ because of city millage, special districts, non-ad valorem assessments like trash and stormwater, an assessed value below the sale price, or the early-payment discount.
