Earthquakes can strike without warning, and the financial impact can be devastating for homeowners. While standard home insurance policies often exclude earthquake-related damages, stand-alone earthquake insurance provides essential protection. Understanding how much coverage you need — and how much it will cost — is crucial for any homeowner living in a seismic-risk zone.
To make this process simple, our Earthquake Insurance Calculator allows you to estimate your coverage amount, annual premium, and monthly premium within seconds. Whether you’re comparing insurance options or budgeting for home protection, this tool gives you clear, accurate insights.
In this comprehensive guide, you’ll learn what earthquake insurance is, how this calculator works, why coverage percentage matters, and how to interpret your results. You’ll also find examples, tips, and a detailed FAQ section to help you make informed decisions.

What Is Earthquake Insurance?
Earthquake insurance is a specialized policy designed to cover damage to your home and belongings caused by seismic activity. Depending on your region, this insurance may be optional or strongly recommended. Areas close to major fault lines—such as California, Alaska, Japan, and parts of South Asia—typically see higher demand for quake coverage.
A typical earthquake policy covers:
- Structural damage to your home
- Damage to interior fixtures
- Personal belongings lost due to the earthquake
- Additional living expenses if you must temporarily relocate
Premiums and coverage vary significantly depending on the home value, location, construction type, and deductible. That’s where an insurance calculator becomes incredibly helpful.
What the Earthquake Insurance Calculator Does
This tool is designed to estimate earthquake insurance premiums based on three simple inputs:
- Home Value – The market value or rebuild cost of your house.
- Coverage Percentage (%) – The percentage of your home value that you want insured.
- Premium Rate (%) – The insurance company’s rate, which determines your annual premium.
Once you enter these values and click Calculate, the tool instantly shows:
- Coverage Amount
- Annual Premium
- Monthly Premium
This gives you a quick snapshot of what your potential earthquake policy might cost.

Step 2: Enter the Coverage Percentage
This determines how much of your home’s value you want covered.
Common options include:

Example Calculation
Let’s walk through a realistic example to better understand how the tool works.
Example Scenario
- Home Value: $500,000
- Coverage Percentage: 60%
- Premium Rate: 1.8%
Step-by-step Breakdown
- Coverage Amount
= Home Value × (Coverage % ÷ 100)
= $500,000 × 0.60
= $300,000 - Annual Premium
= Coverage Amount × (Premium Rate ÷ 100)
= $300,000 × 0.018
= $5,400 - Monthly Premium
= Annual Premium ÷ 12
= $5,400 ÷ 12
= $450
Result
For a $500,000 home, insuring 60% coverage at a 1.8% premium rate would cost you:
- Coverage Amount: $300,000
- Annual Premium: $5,400
- Monthly Premium: $450
This type of estimate helps you understand whether the coverage is affordable or if you need to adjust your percentage or rate.
Tips for Choosing the Right Earthquake Insurance Coverage
1. Evaluate Your Region’s Earthquake Risk
High-risk areas require more coverage and usually have higher premiums.
2. Consider the Age and Type of Your Property
Older homes or properties built with certain materials may need stronger coverage.
3. Calculate Your Rebuild Cost
Home value and rebuild cost are not always the same — the rebuild cost may be higher.
4. Balance Coverage with Affordability
Full coverage offers maximum protection but has higher premiums. Use the calculator to find a realistic balance.
5. Compare Premium Rates
Different insurers offer different rates based on risk assessments, deductibles, and building codes.
