How Much Does Flood Insurance Cost?

FloodSmart, the National Flood Insurance Program’s consumer site, says your flood premium is unique to your property and is based on several factors, including where the property is located, how it is built and what coverage amounts you buy. That is why this page doesn’t publish an average.

What drives an NFIP premium

Category	Examples from FloodSmart
Where it is built	Distance to the coast, rivers and other flooding sources; ground elevation compared with surroundings; community and any Community Rating System discount
How it is built	Occupancy, foundation type (slab vs. basement), first-floor height, number of floors, unit floor, construction type, flood openings, elevated machinery and equipment
What is insured	Building replacement cost value, building and contents limits, deductibles

FloodSmart also notes that higher deductibles can lower your premium, and that discounts may apply for elevating machinery and equipment, installing proper flood openings or being in a participating Community Rating System community.

Coverage limits and timing

• Building coverage up to $250,000 and contents up to $100,000 for a single-family home; contents is purchased separately.
• Renters can buy contents coverage.
• Most policies have a 30-day waiting period, so buying when a storm is approaching is usually too late. The Texas Department of Insurance stresses this point.

Same rates from different sellers

FloodSmart explains that NFIP flood insurance is sold through participating insurance companies and agents, and that NFIP rates are the same no matter which provider sells the policy. Private flood insurance, where available, is priced differently.

Flood zone and mortgage requirements

TDI notes that if your home is in a designated flood zone, your lender requires flood insurance, and that floods can happen anywhere. FloodSmart reports that nearly a third of NFIP claims over a recent 10-year period came from outside high-risk flood zones.

What flood insurance doesn’t cover

FloodSmart lists exclusions such as currency, vehicles, most property outside the building, temporary living expenses and many basement contents. Read the policy before relying on it.

Getting a flood quote

Ask the agent whether flood coverage can be quoted alongside your homeowners quote, the building and contents limits used, the deductibles and the effective date after the waiting period. See does homeowners insurance cover flooding? for the difference between flood, sewer backup and plumbing leaks.

By phone

What happens when you call

A conversation lets the agent ask about your specific home instead of relying on a generic online estimate. There are no online forms to fill out.

1. 1

   Describe your home

   Share the address, size, age, construction, and roof or system updates. You do not need every detail to start.

2. 2

   Talk through coverage

   Explain what you want covered and ask about limits, deductibles, and exclusions that apply to your property.

3. 3

   Compare and decide

   Ask for the written quote terms and compare them before deciding. A call or a quote does not start coverage.
