Earthquake insurance deductible calculator

A percentage deductible is often much larger than homeowners expect — calculate the dollar amount before choosing a deductible percentage.

What you need to know

Earthquake insurance deductible calculator

The Best Earthquake Insurance application calculates a deductible amount in dollars based on your selected percentage and dwelling limit in real time. This is one of the most important calculations to do before purchasing earthquake coverage — because the dollar amount of a percentage deductible at California home values is often surprisingly large.

Key application fields

What the Best Earthquake wizard captures

The application documents all the details underwriters look for. Gathering the following before applying produces a stronger submission and faster broker review:

  • Dwelling limit: enter the requested earthquake dwelling limit
  • Deductible percentage: 5%, 10%, 15%, 20%, or 25%
  • Calculated deductible: the dollar amount you pay before insurance responds
  • Example: $850,000 × 15% = $127,500 out-of-pocket deductible
  • Compare scenarios: see how annual premium changes versus deductible exposure
Why independent broker review matters

From indication to bindable options

The Best Earthquake Insurance application gives a preliminary annual range anchored to CDI data, then submits a completed Covwell application to Bollinsure for broker review. A licensed California broker reviews your construction, retrofit, and loss details and shops multiple carrier markets to find the best available terms.

The indication is not a bindable quote — final coverage is subject to underwriting, carrier eligibility, and policy terms. But starting with a strong, complete application gives the broker the best possible foundation for market submission.

How this fits the application

Ready to submit?

The 5-step application wizard takes approximately 5–8 minutes to complete. It walks through property and applicant details, coverage terms and deductible selection, construction and foundation type, retrofit and loss history, and a review-and-sign step where you can preview the completed PDF before submitting.

Your completed application is reviewed by a licensed broker who follows up — often the same business day — with market options and next steps.
