About Earthquake Insurance

Standard homeowners insurance does not cover earthquake damage. Earthquake insurance is a separate policy — or endorsement — and is most critical in high-seismic-risk states like California, Washington, and Oregon. California has the CEA (California Earthquake Authority) which offers standardized policies. Older homes built before modern seismic codes face significantly higher risk and premiums. Earthquake deductibles are typically expressed as a percentage of your home's insured value (10-25%), making it important to have adequate savings for partial losses.

Frequently Asked Questions

Does homeowners insurance cover earthquakes?

No. Standard homeowners policies specifically exclude earthquake damage. You need a separate earthquake insurance policy or endorsement to be covered.

What is the CEA?

The California Earthquake Authority is a publicly managed, privately funded insurer that provides earthquake coverage to California homeowners. It's one of the largest earthquake insurers in the world.

What is a typical earthquake insurance deductible?

Earthquake deductibles are usually 10-25% of the dwelling coverage amount — far higher than standard homeowners deductibles. On a $500,000 home with 15% deductible, you'd pay $75,000 before insurance kicks in.

How does building age affect earthquake risk?

Older homes — especially those built before 1980 — may use construction methods that perform poorly in earthquakes (e.g., unreinforced masonry, soft-story framing). Retrofitting can improve safety and lower premiums.

Is earthquake insurance worth it outside California?

In moderate-risk areas like the Pacific Northwest and the New Madrid Seismic Zone in the Midwest, earthquake insurance can be cost-effective. In very low-risk areas, it's usually not worth the added expense.

About This Earthquake Insurance Cost Calculator

The Earthquake Insurance Cost Calculator helps you make smarter insurance decisions by turning complex coverage variables into clear, actionable numbers. Simply enter your details above and the calculator instantly shows you realistic estimates based on the key factors that insurers use to determine your costs.

Insurance professionals, financial planners, and consumers alike use home insurance calculators to benchmark costs, identify savings opportunities, and make informed coverage decisions. Rather than relying on guesswork or generic industry averages, this calculator applies the specific inputs you provide to generate a range that reflects your situation.

When interpreting results, keep in mind that actual home insurance premiums depend on many additional factors — including your credit history, exact location, prior claims, and the specific insurer's underwriting guidelines. The figures here represent a realistic estimate range, not a guaranteed quote. Use them as a starting point for conversations with licensed agents who can provide binding quotes from multiple carriers.

For the most accurate results, have your current policy documents nearby when entering inputs. Compare the output with at least two or three actual quotes to see how well the estimate aligns with real-world pricing in your market. Estimates can vary significantly by state and insurer, so shopping around remains the single most effective way to reduce your home insurance costs.

Results are estimates only. Actual earthquake insurance premiums depend on precise location, soil type, construction details, and insurer underwriting. Consult a licensed insurance professional for accurate quotes.
