What it means
The National Association of Insurance Commissioners explains that a deductible is the amount of loss paid by the policyholder before the insurer pays. For most perils, such as fire and theft, it can be a percentage of insured value or a flat amount such as 500 or 1,000.
In many coastal states, homeowners policies also carry a deductible that applies only to hurricane damage. The NAIC says it is applied separately from standard peril deductibles and is typically higher.
It can be a fixed amount or, more commonly, a percentage of the home's insured value, which can vary from 1 percent to as high as 15 percent. A named storm deductible is wider.
It covers categorised hurricanes and also weather events such as a tropical storm or cyclone that have been given a name by the National Weather Service or National Hurricane Centre. Definitions vary by policy.
The NAIC page says these deductibles were introduced as a risk-sharing mechanism, so insurers could keep premiums from becoming unaffordable. They were first used in 1992 after Hurricane Andrew, and spread widely after Hurricane Katrina in 2005.
As of June 2025, the NAIC said 19 states and the District of Columbia had some form of hurricane or named storm deductible in place. Whether the deductible applies depends on a trigger chosen by the insurer and set out in the policy, often shaped by state law.
The NAIC notes that no two state laws are identical, and triggers vary by state and insurer. Some policies add a windstorm or wind and hail deductible.
A tree falling on a roof on a windy day would be subject to that deductible. Flood or storm surge damage is covered only with a separate flood policy.
The Texas Department of Insurance says windstorm cover along the coast may require a separate policy, and that you may have a different deductible for windstorm damage. This entry gives US examples, and the policy wording controls.
In practice
Real-world examples.
Example
A fictional coastal homeowner has a 2% hurricane deductible on a home insured for $250,000. A named hurricane damages the roof, and the 2% applies, giving a deductible of $250,000 x 0.02 = $5,000 rather than the standard deductible. The homeowner budgets for that sum before storm season.
Example
A fictional policy has a flat $1,000 deductible for most perils and a percentage deductible for named storms. A kitchen fire is paid with the $1,000 deductible. A hurricane claim uses the higher storm deductible, so the homeowner keeps both figures noted beside the policy.
Example
A fictional homeowner reads that the policy's trigger depends on the storm being named. A thunderstorm tree fall is handled under the wind deductible instead. The trigger in the policy decides which deductible applies, so the homeowner asks the insurer to confirm it in writing.
Formula
Calculation
Hurricane deductible = insured value x deductible percentage. Insurer pays = covered loss - deductible, if the loss exceeds it; otherwise the insurer pays nothing.
Worked example with assumed figures: insured value $300,000 and a 2% hurricane deductible. Deductible = $300,000 x 0.02 = $6,000.
If the covered hurricane loss is $20,000, the insurer pays $20,000 - $6,000 = $14,000. If the loss is $5,000, the insurer pays nothing, since the loss is below the deductible and the homeowner bears the whole $5,000.
The same home with a 5% deductible would carry $300,000 x 0.05 = $15,000, which shows why the percentage matters as much as the premium. The figures are assumptions for illustration.Case study
Seen in the real world.
This case study is fictional and illustrative. A homeowner on a coastal strip has a policy with a $1,000 standard deductible and a 5% hurricane deductible. The home is insured for $300,000. A named storm tears off part of the roof, and repairs cost $22,000.
The hurricane deductible is $300,000 x 0.05 = $15,000. The insurer pays $22,000 - $15,000 = $7,000. The homeowner pays $15,000, far more than the standard deductible would have required. The homeowner had not read the declarations page, which lists the deductible.
A flood claim for water that came in with the surge would need a separate flood policy. The following year the homeowner set aside a storm fund equal to the hurricane deductible and asked the insurer what premium saving a lower percentage would cost. The lesson is to check the percentage, the trigger and the insured value before the season.
Watch out
Common mistakes.
- Assuming the standard deductible applies to a storm, when a separate hurricane or named storm deductible may apply.
- Reading the percentage as a flat amount, when it is usually applied to insured value.
- Ignoring the trigger, since policies set the conditions that start the deductible and state laws differ.
Questions

What is a hurricane deductible?
It is a separate deductible that applies only to damage from a hurricane or named storm. It is usually a percentage of insured value.
How is it different from a standard deductible?
It is applied separately and is typically higher. The NAIC says it can range from 1 percent to as high as 15 percent of insured value.
Does it cover flood damage?
No. The NAIC says flood or storm surge damage is covered only if a separate flood policy was purchased.
