Flood Insurance Cost Calculator

Across 303,299 single-family NFIP policy terms beginning 2026-05-01 to 2026-06-10, the median annual policy cost was $1,187, with the middle half falling between $785 and $1,513. That spread is the honest answer: flood premiums vary far more than a single average suggests. The zone is the fastest way to narrow it — the median is $989 in Zone X, $972 in Zone A, $1,375 in Zone AE and $1,833 in coastal Zone VE. These are policy costs including the federal policy fee and HFIAA surcharge, computed from FEMA's own published policy data rather than from quotes.

The median annual cost across 145,882 Zone AE single-family policies is $1,375. Within Zone AE the largest single driver is how the lowest floor sits relative to Base Flood Elevation: at the full $250,000 of building coverage, the median is $2,053 for a property below BFE against $1,073 for one four or more feet above it. That is a 1.9× spread inside a single flood zone, which is why "how much is flood insurance in Zone AE" does not have one answer. Coverage amount and whether the building is pre- or post-FIRM move it further.

No. Standard homeowners policies exclude flood, and that exclusion is why the National Flood Insurance Program exists as a separate product. FEMA's own consumer guidance states that most homeowners and renters insurance does not cover flood damage and that only a flood insurance policy will help you recover after a flood. Flooding for exclusion purposes means water arriving from outside — storm surge, overflowing rivers, surface water, heavy rainfall accumulation. A burst pipe inside the home is a different peril and is normally covered by the homeowners policy. Anyone comparing a flood premium against a homeowners premium is comparing two products that do not substitute for each other.

It is required by federal law for a federally backed mortgage on a property in a Special Flood Hazard Area, in a community that participates in the NFIP. Zones beginning with A — including A, AE, AH, AO, A99 and AR — and the coastal V and VE zones are the high-risk areas where that mandate applies. Outside those zones, in Zone X, coverage is optional and a lender cannot require it. Optional is not the same as unnecessary: Zone X policies are the cheapest in FEMA's data, and NFIP pays claims on properties outside mapped high-risk areas every year.

NFIP caps a residential policy at $250,000 of building coverage and $100,000 of contents coverage, and those limits hold regardless of what the home is worth. Rebuild cost above the building limit is simply uninsured under NFIP, which is the main reason owners of higher-value homes buy private flood insurance or an excess flood policy stacked on top. Contents coverage is a separate purchase from building coverage — a building-only policy pays nothing toward the belongings inside. The estimate on this page is matched on building coverage alone — contents coverage is not one of its inputs, so price it as a separate line rather than reading it into the figure.

Not on its own, not any more. FEMA's consumer guidance states that flood zones and the structure's elevation relative to Base Flood Elevation are no longer the only factors used in setting flood insurance premiums. Distance to a flooding source and what kind of source it is, the cost to rebuild the specific building, foundation type and prior claims all now feed the rate. That is why this calculator reports the median and the middle-half range of what real policies in your situation cost, alongside the number of policies behind the figure, rather than pretending a zone multiplied by a coverage amount produces your price.

NFIP coverage generally begins 30 days after purchase, and FEMA names four exceptions: there is no wait when you buy while making, increasing, extending or renewing a mortgage; no wait when you change coverage at renewal; a one-day wait if your property has just been mapped into a high-risk zone and you buy within 12 months of the change; and a one-day wait if a flood is caused or worsened by wildfire on federal land and you buy within 60 days of containment. The practical consequence is that you cannot buy coverage against a storm already in the forecast.

In the high-risk zones, frequently. Alongside what each policy currently costs, FEMA publishes a full-risk premium for the same property — the price that reflects its assessed flood risk. The comparison has to be made net of the federal policy fee, HFIAA surcharge and reserve fund assessment, because policy cost includes those three and the full-risk premium does not. Done that way, Zone AE policies pay a median of $1,057 against a full-risk premium of $1,549, and Zone VE $1,396 against $2,096 — both meaningfully below full risk and climbing toward it. In Zones A and X the gap is already closed, at $731 against $760 and $754 against $777. So a high-risk-zone premium quoted today is better treated as a floor than a settled figure; a Zone X one is more stable.
