Florida Mortgage Calculator

Compute the real cost of a Florida home — not just the principal-and-interest payment. Layers in property tax under F.S. § 200.001, hurricane-loaded homeowners insurance under F.S. § 627.4133, HOA dues, and the Florida-specific closing-cost stack other mortgage calculators miss: deed documentary stamps (F.S. § 201.02), mortgage documentary stamps (F.S. § 201.08), the non-recurring intangible tax (F.S. § 199.133), and OIR-promulgated title insurance (F.S. § 627.7825). Surfaces cash to close, monthly all-in (PITI + HOA), affordability against the 28/36 rule, and total cost of ownership over the full loan term.

Florida county. Drives the typical total millage (used for the property-tax estimator), the coastal-vs-inland HOI default, and the customary owner's-title-policy payer convention (buyer-pays in Miami-Dade, Broward, Sarasota, and Collier; seller-pays elsewhere). For an exact bill, pull the millage from the parcel's TRIM notice and override below.

Single-family residential or condominium. Drives the framing of the Miami-Dade deed-stamp rate (the $0.60/$100 rate applies to SFR; a single condo unit in Miami-Dade is technically non-SFR and pays the surtax — for that case, use the Documentary Stamp Tax Calculator). Does not change Pinellas / statewide math.

How this calculator works

A generic mortgage calculator answers a narrow question: given a loan amount, an interest rate, and a term, what is the monthly principal-and-interest (P&I) payment? In Florida, that number captures roughly 60-70% of what actually leaves a homeowner's bank account each month. The remainder sits in four Florida-specific line items that generic calculators ignore:

  1. Property tax under F.S. § 200.001 and the rest of Chapter 200. At a Florida-typical 19 mills, a $400,000 home generates about $7,600 per year, or roughly $633 per month, before any homestead exemption. In year one of a new purchase, the Save Our Homes assessment cap under F.S. § 193.155 has not yet built up, so you pay the full ad valorem amount on just value.
  2. Homeowners insurance (HOI) under F.S. § 627.4133. Florida HOI is among the most expensive in the country because of hurricane and windstorm exposure. Typical 2026 figures: about $3,500 per year for an inland single-family home, $6,500 per year for a coastal single-family home, materially higher with separate flood coverage in flood zones.
  3. HOA or condominium dues, common in Florida new-construction subdivisions and condo buildings. Post-Surfside, condo dues have risen sharply under the structural-integrity reserve mandate of F.S. § 718.112(2)(g).
  4. The Florida closing-cost stack — paid once at closing rather than monthly, but large enough that no honest mortgage calculator can skip it: deed documentary stamps under F.S. § 201.02, mortgage documentary stamps under F.S. § 201.08, the non-recurring intangible tax under F.S. § 199.133, and OIR-promulgated title insurance under F.S. § 627.7825.

This calculator runs all of it in one pass and surfaces three numbers that matter: the monthly P&I (the conventional headline), the total monthly all-in (P&I plus escrowed taxes plus escrowed insurance plus HOA), and the cash to close (down payment plus the buyer-paid Florida closing costs). It also surfaces total interest paid over the loan term and total cost of ownership — principal plus interest plus 30 years of tax, insurance, and HOA — so you can see how much of "owning a Florida home" is not the mortgage payment.

The Florida closing-cost stack

This is the part generic mortgage calculators miss. Every Florida real-estate closing carries a stack of state-level transactional taxes and OIR-promulgated insurance premiums that other states either do not impose or impose at materially different rates. The pieces:

  • Deed documentary stamps (F.S. § 201.02) — $0.70 per $100 of consideration statewide; $0.60 per $100 in Miami-Dade County on single-family residential transfers under the home-rule carve-out preserved by F.S. § 201.031. On a $400,000 sale that is $2,800 statewide or $2,400 in Miami-Dade. Customarily seller-paid in Florida.
  • Mortgage documentary stamps (F.S. § 201.08) — $0.35 per $100 of the face amount of the promissory note. Statewide; no county variation. On a $320,000 loan that is $1,120. Customarily buyer-paid.
  • Non-recurring intangible tax (F.S. § 199.133) — 2 mills per dollar of mortgage amount, or $2.00 per $1,000. On a $320,000 loan that is $640. A holdover from Florida's broader intangible personal property tax (largely repealed 2007) preserved as a stand-alone mortgage tax at recording. Customarily buyer-paid.
  • Title insurance owner's policy (F.S. § 627.7825) — promulgated by the Florida Office of Insurance Regulation under OIR Rule 69O-186.003 at a five-tier per-thousand schedule: $5.75 per $1,000 on the first $100,000, $5.00 per $1,000 on $100K-$1M, $2.50 per $1,000 on $1M-$5M, $2.25 per $1,000 on $5M-$10M, and $2.00 per $1,000 above $10M. On a $400,000 home: $575 plus $1,500 equals $2,075. Customarily seller-paid in most counties; customarily buyer-paid in Miami-Dade, Broward, Sarasota, and Collier.
  • Title insurance lender's policy (simultaneous-issue) — flat $25 when issued at the same closing as the owner's policy on residential under $1M (OIR Rule 69O-186.003). Always buyer-paid.

Customary allocation is what most Florida title agents put on the Closing Disclosure unless the contract specifies otherwise. The Florida Realtors / Florida Bar standard contract at Paragraph 9 encodes the convention. For the buyer's cash-to-close figure, what matters is the buyer-paid portion: in a Pinellas (statewide) purchase, that is the mortgage stamps plus intangible plus lender's policy, with the owner's policy customarily on the seller's settlement side. In a Miami-Dade purchase, the owner's policy is added to the buyer's side.

A worked example: $400K Pinellas single-family home

A buyer purchases a $400,000 single-family home in Pinellas County (statewide rate jurisdiction) with 20% down, financing $320,000 at 7.0% for 30 years. The buyer is using an inland-typical HOI premium of $3,500 per year and the Pinellas-typical 19-mill total millage. The home is not in an HOA.

Monthly payment:

  • Monthly P&I: $320,000 at 7.0% / 30y = $2,128.92
  • Monthly property tax: ($400,000 x 19 / 1,000) / 12 = $633.33
  • Monthly HOI: $3,500 / 12 = $291.67
  • Monthly HOA: $0
  • Total monthly all-in: $3,053.92

Note that the headline P&I (about $2,129) is roughly 70% of the actual monthly outlay (about $3,054). The other $925 per month is property tax and insurance — neither of which is a "lender" cost. Both continue forever, including after the mortgage is paid off.

Florida closing-cost stack:

  • Deed documentary stamps (seller's customary side): $400,000 / 100 x $0.70 = $2,800
  • Mortgage documentary stamps (buyer's side): $320,000 / 100 x $0.35 = $1,120
  • Non-recurring intangible tax (buyer's side): $320,000 x 0.002 = $640
  • Owner's title insurance premium (seller's customary side in Pinellas): $575 + $1,500 = $2,075
  • Lender's title insurance (buyer's side, simultaneous-issue flat): $25
  • Total Florida closing costs: $6,660

Cash to close:

  • Down payment: $80,000
  • Buyer-paid Florida closing costs (mortgage stamps + intangible + lender's policy): $1,120 + $640 + $25 = $1,785
  • Buyer cash to close (Florida portion): $81,785

(The full cash-to-close on the Loan Estimate will also include lender origination fees, appraisal, survey, recording fees, prepaid escrow deposits, and per diem interest — items that are not Florida-specific and that we do not model here. Pull those from the lender's Loan Estimate.)

Total 30-year cost of ownership:

  • Principal: $320,000
  • Total interest paid (monthly P&I x 360 minus principal): approximately $446,412
  • 30 years of property tax at $7,600 per year: $228,000
  • 30 years of HOI at $3,500 per year: $105,000
  • 30 years of HOA at $0: $0
  • Total 30-year cost of ownership: approximately $1,099,412

The single most counterintuitive number on this list is the 30-year property tax and insurance total: about $333,000 of ownership cost that no generic mortgage calculator surfaces and that does not go away when the mortgage is paid off. On a $400,000 home, a Florida buyer pays roughly the equivalent of another whole purchase price in tax and insurance over a 30-year horizon. That is a separate conversation from the mortgage decision — but one a buyer should have before signing the contract.

A note on Miami-Dade

The Miami-Dade variant of the same $400,000 purchase shifts two numbers materially. The deed-stamp rate is $0.60 per $100 instead of $0.70 (saving the seller $400), but the owner's title insurance policy is customarily buyer-paid in Miami-Dade (adding $2,075 to the buyer's cash-to-close). Net: the buyer's cash-to-close in Miami-Dade runs about $2,075 higher than the same purchase in Pinellas, even though the deed-side rate is cheaper. The same flip applies in Broward, Sarasota, and Collier — three of the four are coastal high-value counties where the relocating-buyer surprise is largest.

What this calculator does NOT do

This is a Florida-specific estimator. It does not:

  • Replace the lender's Loan Estimate. Origination fees, discount points, appraisal, survey, recording fees, prepaid escrows, and per diem interest are non-Florida-specific items that vary by lender and that you should pull from the LE rather than estimate. The Florida portion of the closing costs surfaced here is consistent across lenders because it is statutorily fixed.
  • Apply the F.S. § 196.031 homestead exemption or the F.S. § 193.155 Save Our Homes cap. Both apply in year two and beyond of a homestead claim and reduce the property-tax line by approximately $900 per year in year one and meaningfully more over time. For the exact bill, use the Florida Property Tax Calculator.
  • Compute the exact deed-stamp and intangible-tax math on edge cases. Mortgage assumptions, refinance modifications, like-kind exchanges, and no-consideration transfers (gifts, divorce-incident transfers, transfers to revocable trusts) all have nuances under F.S. § 201.02 and F.S. § 199.133. For those, use the Documentary Stamp Tax Calculator.
  • Compute reissue credit on title insurance. A prior owner's policy issued less than 3 years before the new closing qualifies for a 30% reissue discount under F.S. § 627.7825. For a refinance or a quick second-sale scenario, use the Title Insurance Calculator.
  • Compute mortgage insurance (PMI / MIP) or escrow shortage / overage. PMI is required on conventional loans with under 20% down (Homeowners Protection Act, 12 USC § 4901); FHA MIP runs for the life of the loan on FHA originations after June 2013 with under 10% down; VA loans carry no monthly mortgage insurance. Escrow shortage / overage is calibrated by the lender annually under RESPA. None of those are Florida-specific.
  • Substitute for a Florida-licensed mortgage broker or financial planner. For the actual loan decision — comparing 15-year vs 30-year products, conventional vs FHA vs VA, fixed vs adjustable, and the timing of the lock — consult a Florida-licensed mortgage broker or financial planner before acting on the calculator's output.

Common questions

Edge cases and clarifications around florida mortgage calculator.

A generic mortgage calculator computes principal-and-interest from loan amount / rate / term and stops there. In Florida, that number captures roughly 60-70% of the actual monthly outlay. The missing pieces are Florida-specific: (1) property tax at a typical 19 mills runs about $633/mo on a $400K home — and there is no Save Our Homes cap protecting you in year one; (2) homeowners insurance averages $3,500/yr inland and $6,500/yr coastal because of hurricane and windstorm exposure under F.S. § 627.4133; (3) HOA or condo dues, common in Florida new-construction and condo markets. Plus the one-time Florida closing-cost stack — deed stamps (§ 201.02), mortgage stamps (§ 201.08), intangible tax (§ 199.133), title insurance (§ 627.7825) — that no other state imposes in the same configuration. The 'real' Florida monthly is the P&I plus escrowed taxes and insurance plus HOA — what lenders call PITI plus HOA, what we surface as 'total monthly all-in'.
