This calculator gives a rough estimate based on basic loan factors. It does not include every fee, cost, or variation that may apply to your situation, and Florida insurance in particular varies widely by age of roof, elevation and windstorm coverage. To work backward from your income instead, use the home affordability calculator.

Good to Know
What is PMI?
Private Mortgage Insurance is required when your down payment is less than 20%. It typically costs 0.5% to 1% of the loan annually.
Florida has no state income tax
This significantly reduces overall tax burden for homeowners compared to states like New York or California.
Homestead Exemption
Florida residents may qualify for a homestead exemption that reduces assessed home value by up to $50,000 for tax purposes.
How the mortgage calculator works
This tool estimates the monthly principal and interest on a fixed-rate loan using the standard amortization formula M = P[r(1+r)^n]/[(1+r)^n-1], where P is the loan amount, r is the monthly rate (annual rate divided by 12), and n is the number of payments. Each payment covers interest first, then reduces the balance.
For example, a $450,000 home with 20% down leaves a $360,000 loan. At a 6.9% annual rate over 30 years, r is 0.00575 and n is 360, which works out to about $2,371 per month in principal and interest. Rate figures here are illustrative only, not a quote.
Principal and interest is only part of a South Florida payment. This estimate excludes the property taxes, homeowners and flood insurance, and any condo or HOA dues that push real monthly costs higher here. Use it to compare loan amounts and rates, then add those local costs to see the full picture before you make an offer.
