Your storm deductible, in dollars

Your storm deductible is not your regular deductible
$3,000

A typical 1% catastrophe deductible on $300,000 of coverage means you pay the first $3,000 of storm damage yourself 3x the $1,000 deductible that applies to everything else. That is $2,000 more you would need on hand after a named storm than after a kitchen fire.

Iowa is landlocked and does not appear on the Insurance Information Institute's list of nineteen states plus DC with hurricane or named-storm deductibles. The separate deductible that matters here is for WIND AND HAIL, and Iowa is one of the clearest Midwest cases of it. Separate wind/hail deductibles are common on Iowa policies and are typically written as 1% to 5% of the dwelling limit rather than a flat dollar amount: on a $300,000 dwelling limit a 1% deductible is $3,000 and a 5% is $15,000, against the $1,000 shown for everything else. THE DERECHO IS WHY. The August 10, 2020 Midwest derecho -- which the National Weather Service called the costliest severe thunderstorm event in United States history, with damage estimated above $11 billion, much of it concentrated in Cedar Rapids and eastern Iowa -- materially reset this market. Carriers tightened underwriting, raised wind/hail deductibles, and in some cases stopped writing. Iowa Insurance Division consumer-advocate commentary dates the sustained rate increases in the state to that event. The 1% recorded here is the low end of the documented 1%-to-5% range and is a representative figure rather than a measured statewide mode. For an Iowa homeowner the practical point is blunt: wind and hail is the claim you are most likely to file, and it is the one claim your $1,000 deductible does not cover.

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.
