How to use this calculator

This Florida mortgage calculator estimates your full monthly housing cost — not just principal and interest, but the line items that catch new buyers off guard. Plug in your home price, down payment, interest rate, and loan term, then add Florida-specific costs: property tax, hurricane-rated homeowner's insurance, HOA dues, and PMI if you're putting down less than 20%.

Principal & Interest

This is the portion of your payment that goes to your lender. It's calculated using the standard amortization formula: M = P [ i(1+i)^n ] / [ (1+i)^n − 1 ], where P is the loan amount, i is the monthly interest rate, and n is the number of monthly payments. For a $360,000 loan at 6.5% over 30 years, the principal & interest payment runs about $2,275 per month — and you'll pay roughly $459,000 in interest over the life of the loan.

Florida property taxes

Florida's average effective property tax rate hovers around 0.80%–0.90%, but actual bills vary widely by county and city. Miami-Dade, Broward, and Palm Beach trend higher; rural counties like Jackson and Holmes trend lower. If the home will be your primary residence, claim the Florida Homestead Exemption — it shaves about $51,000 off your taxable value and caps annual increases at 3% or CPI.

Homeowner's insurance in Florida

Florida homeowner's insurance is the highest in the nation due to hurricane exposure and litigation history. A typical single-family policy runs $2,400 to $6,000+ per year. Older homes, coastal properties, and homes without wind mitigation upgrades pay more. Newer construction and homes with hurricane shutters, impact windows, or upgraded roofs often qualify for wind mitigation credits that can cut the premium 20%–40%.

Flood insurance (separate from HOI)

Standard homeowner's policies do not cover flood damage. If your property sits in a FEMA Special Flood Hazard Area (Zones AE, VE, A, or AO), your lender will require a separate flood policy through the NFIP or a private carrier. Even outside the high-risk zones, flood insurance is recommended in Florida — about 40% of NFIP claims come from properties outside the mapped flood zones. See the Florida flood zones guide for zone definitions and rate ranges.

HOA dues

Florida has more HOAs and condo associations per capita than almost any other state. Monthly dues range from $25 in a deed-restricted subdivision to $1,000+ in a high-rise condo with amenities. Always factor HOA dues into your monthly payment — they affect your debt-to-income ratio and what you can qualify for.

PMI — when it applies and when it falls off

Private Mortgage Insurance is required on conventional loans when your down payment is less than 20%. PMI typically costs 0.3%–1.5% of the loan amount annually. Under the federal Homeowners Protection Act, your lender must automatically cancel PMI when your loan-to-value reaches 78% of the original purchase price. You can request earlier cancellation at 80% LTV if you're current on payments and the home hasn't dropped in value.

Florida-specific buyer tips

Beyond the monthly payment, budget for these one-time and recurring Florida costs:

• Documentary stamp tax on the deed — $0.70 per $100 of sale price (Miami-Dade is $0.60 plus $0.45 surtax). On a $450,000 home, that's about $3,150.
• Doc stamps and intangible tax on the mortgage — $0.35 per $100 plus 0.002% intangible. Roughly $1,980 on a $360,000 loan.
• Title insurance — usually paid by the seller in Florida, but negotiable. Promulgated rate of about 0.575% on the first $100K, then sliding down.
• 4-point inspection — most insurers require one for homes 25+ years old. $100–$200.
• Wind mitigation inspection — $75–$150, often pays for itself in insurance discounts.
