Since 1978 the National Flood Insurance Program has paid $19.33 billion on 313,527 flood claims in Florida. The median paid claim was $19,287.
Premium figures tell you what cover costs. Claims tell you how often it gets used, where, and for what. This section covers the second question.
Official source figures, as of 14 August 2026. Calculated from National Flood Insurance Program policy records published by FEMA. These are premiums other policyholders paid, not a quote or an offer of coverage.
One in eight paid claims came from a zone where cover is optional
Of the 313,527 Florida claims that resulted in a payment, 40,039 were on properties rated in zones X, B, C or D. Those are the zones outside the Special Flood Hazard Area, where no mortgage lender requires you to carry flood cover. That is 12.8% of all paid claims, and $1.56 billion paid out.
The reason becomes obvious once you look at what actually caused the damage.
Outside the floodplain, two in three claims are rainfall
FEMA records a cause of loss on every claim. Across Florida, rainfall accumulation accounts for 67.1% of claims in the optional zones, against 52.6% in the high-risk zones.
Flood maps are drawn around water that rises out of a channel or comes in off the sea. Rain that falls faster than the ground and the drains can take it does not respect that boundary, and it is the single most common cause of a Florida flood claim.
Rain is more frequent. The sea is more expensive.
Rainfall caused 208,244 claims with a median payment of $14,687. Tidal water overflow caused 138,475 claims, fewer in number, but with a median payment of $29,000, almost exactly double.
Both matter, and they are not the same risk. A property inland faces the frequent, cheaper version. A property on the coast faces both.
The median claim involves two inches of water
Where depth was recorded, the median was two inches. Nine in ten claims came in under a foot.
That is worth sitting with. Half of all Florida flood claims involve water that would not reach the top of your shoe, and the median payment across the whole programme is $19,287. Flood damage is not mainly about dramatic depth. It is about what water does to drywall, flooring, wiring and everything stored at floor level.
Where these numbers come from
Every figure on this page is calculated from the FEMA OpenFEMA NFIP claims file, filtered to Florida. Claims are anonymised by FEMA to ZIP code and census tract, so nothing here identifies an individual property, and nothing here can tell you whether one particular house has flooded.
What it can tell you is how often the programme has paid out in an area, for what, and how much. Read the full method, or browse what each named event cost.
