Wind Deductible Calculator

Coastal and hurricane-exposed properties have separate wind or 'named-storm' deductibles — typically 3-5% of building value. A $2M building with 5% wind deductible eats $100K before insurance pays. This calculator sizes the deductible gap versus the standard all-perils deductible.

How the math works

Coastal properties (FL, LA, TX Gulf) commonly carry 3-5% named-storm deductibles — $60-$100K on a $2M building. This kicks in specifically on named windstorms; regular wind damage uses the all-perils deductible. Huge difference at claim time.

Wind mitigation credits (hurricane straps, impact windows, upgraded roof) can reduce wind deductibles by 10-25%. Required documentation and inspector sign-off but very worth pursuing.

How to Use

  1. Enter building replacement cost.
  2. Enter wind / named storm deductible percent.
  3. Enter standard all-perils deductible.
  4. Enter estimated wind claim.
  5. Read deductible, claim payout, and gap vs standard deductible.

Frequently Asked Questions

Named storm vs wind?

Named storm = officially named tropical storm or hurricane. Regular wind = tornado, microburst, severe wind without name. Some policies treat both as 'wind deductible'; others separate. Read the policy wording.

Mitigation credits?

Florida and Texas allow documented wind mitigation (hurricane straps, impact glazing, upgraded roof) to reduce wind deductible. Annual savings can be 10-25% — very worth the mitigation cost.

Annual aggregate vs per-event?

Per-event is standard — each named storm triggers deductible independently. Annual aggregate caps total out-of-pocket but is rare and pricey. Most coastal landlords stick with per-event.
