What your storm deductible actually comes to in dollars, and whether raising your regular deductible is worth the exposure. Estimates only — not a quote.

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.

South Dakota has no coast and no hurricane deductible, but it sits in Hail Alley and a separate PERCENTAGE wind and hail deductible is common here for that reason - which is exactly the Midwest/Plains case the schema means to capture. Typical selections run 1% to 5% of the dwelling limit; Insurify's May 2026 study measures South Dakota's statewide average wind/hail deductible at 1.81% of dwelling coverage, or about $5,213 in dollar terms, the fourth-highest percentage in the country behind Texas, New Jersey, and Massachusetts. On a $300,000 dwelling limit a 2% wind/hail deductible is $6,000 out of pocket. The trigger is broad: unlike a named-storm deductible, this applies to ordinary severe-thunderstorm hail and straight-line wind, which in South Dakota is not a rare event but the routine one. Some policies still use a flat wind/hail deductible ($1,000 or $2,000) instead of a percentage, and roof-age underwriting frequently rides alongside it, so a South Dakota declarations page needs to be read for both the percentage and any roof settlement schedule.

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.
