Your storm deductible, in dollars

Your storm deductible is not your regular deductible
$6,000

A typical 2% catastrophe deductible on $300,000 of coverage means you pay the first $6,000 of storm damage yourself 6x the $1,000 deductible that applies to everything else. That is $5,000 more you would need on hand after a named storm than after a kitchen fire.

Mississippi is one of 19 states plus DC that use hurricane or named-storm deductibles, and on the Gulf Coast a separate named-storm deductible is the norm rather than an option. Mississippi Insurance Department regulation (19 Miss. Code R. Part 1 Chapter 41, 'Named Storm Deductible and Hurricane Deductible') does not force insurers to use one, but sets the rules when they do: the deductible must be expressed as a percentage of the insured value, the insurer must file and use approved uniform policy language, and the insurer must offer a buy-back provision letting the homeowner buy the percentage deductible back down for extra premium. The trigger period starts when the National Hurricane Center issues a watch or warning for Mississippi and ends 24 hours after the last such warning for any part of the state is terminated -- so it is state-wide-trigger, not damage-location-based. Typical percentages run 1% to 5% of Coverage A; 2% is the common selection and is the maximum most mortgage programs will accept (Mississippi's Veterans Home Purchase Board caps required deductibles at 2%, allowing 5% only in limited circumstances). The Mississippi Windstorm Underwriting Association offers a 2% named-storm deductible on dwelling and mobile-home risks. On a $300,000 dwelling limit, 2% is $6,000 and 5% is $15,000 -- against a $1,000 all-perils deductible for everything else. NOT law, but worth knowing: HB 1479 (2025 Regular Session) would have required these deductibles to apply once per calendar year rather than per storm and mandated a signed disclosure form; it died in committee on February 4, 2025, so per-occurrence application remains the default here, unlike Florida.

Is a higher deductible worth it?

This needs your two real quoted premiums. We deliberately don’t apply a “typical savings” percentage: deductible credits vary by carrier, state, and filing, so a made-up multiplier would give you a break-even that looks precise and isn’t. Ask your insurer to quote both deductibles — it takes one phone call, and the answer is specific to you.
