📐 How We Calculate This
Our insurance estimates use actuarial models based on publicly available rate filings, NAIC data, and national averages from the Insurance Information Institute. Factors include age, location, coverage level, claims history, and asset value.
Premiums vary significantly by state and insurer. This calculator provides a baseline estimate — we recommend comparing quotes from at least 3 licensed carriers for accurate pricing.

Does homeowners insurance cover earthquake damage?
No. Standard homeowners insurance policies explicitly exclude earthquake damage. You need a separate earthquake insurance policy or an endorsement to your existing policy. This is true nationwide — even in low-risk areas. In California, the CEA (California Earthquake Authority) is the primary provider, while private insurers offer coverage in other states.
Why are earthquake insurance deductibles so high?
Earthquake deductibles are percentage-based (typically 10–25% of coverage amount) rather than flat dollar amounts. This is because earthquake damage tends to be catastrophic and widespread, making flat deductibles impractical for insurers. A 15% deductible on a $400,000 home means you pay the first $60,000 out of pocket. Higher deductibles significantly reduce your premium.
Is earthquake insurance worth it?
It depends on your risk level and financial situation. If you live in a high seismic zone (California, Pacific Northwest, Alaska), have a mortgage, or couldn't afford to rebuild, earthquake insurance is generally worth it. Even with high deductibles, it protects against total loss. In low-risk areas, the cost-benefit may not justify the premium unless you have a high-value home.
What does earthquake insurance actually cover?
Earthquake insurance typically covers three things: dwelling coverage (structural repairs to your home), personal property (furniture, electronics, clothing), and additional living expenses / loss of use (hotel and food costs if your home is uninhabitable). It does not usually cover external structures like fences and pools, vehicles, or land damage. Some policies offer optional coverage for masonry veneer and breakable items.
How does my foundation type affect earthquake insurance?
Foundation type significantly impacts both your risk and premium. Homes bolted to their foundation or on concrete slabs perform best in earthquakes (lower premiums). Homes with cripple wall foundations (short wood-framed walls between the foundation and first floor) are most vulnerable and cost much more to insure. Retrofitting a cripple wall can reduce premiums by 5–20% and is often required by the CEA in California.
