Florida Financial Snapshot (2026) — Down Payment Savings Calculator
Home value, monthly carrying cost, property tax, and insurance are the four levers for the down payment savings calculator in Florida.
How the Down Payment Savings Calculator Math Works Under Florida Law
Every real-estate number on this page runs through the same core identity: the monthly principal-and-interest payment on a fully amortizing fixed-rate loan is M = P · r / (1 − (1+r)^(−n)), where P is the loan principal, r is the monthly rate (annual rate / 12), and n is the term in months. For a typical Florida buyer in 2026, P starts from an $395,000 median home value (Zillow ZHVI)[1], minus a standard 20% down payment.
On top of P&I the calculator adds the two Florida-specific carrying costs: property tax at the state effective rate of 0.89%[2] and homeowners insurance at roughly $7,136/year (NAIC state average)[3]. The Freddie Mac PMMS national average 30-year fixed rate (6.30% (Freddie Mac PMMS · week of ))[4] drives the payment curve — Florida rate quotes can move a few basis points around that number depending on lender, loan size, and credit band.
