Insurance policies are written in a vocabulary that nobody teaches. Premium, deductible, limit, endorsement, rider, exclusion, peril — these words have precise meanings that determine exactly what you are owed after a loss.
This section is the reference layer of the site. It exists so the rest of the guides can be read without a dictionary.
What you'll find in this section
- The three numbers that matter. Premium, deductible and limit — and why the limit is usually the one people get wrong.
- How to read a declarations page. The one-page summary of everything your policy actually promises.
- Endorsements and riders. The add-ons that change coverage, sometimes significantly.
- Named perils versus open perils. Whether your policy lists what's covered, or lists what isn't.
Where to start
If you read only one thing here, make it the guide to your declarations page. It is one or two pages, it summarizes your entire policy, and almost nobody reads it until after a loss.
Published guides

What a Declarations Page Tells You (Line by Line)
Two pages that determine most of what happens if you ever file a claim.
Before you act on this
This page explains a general process. It is not advice about your specific policy or claim. Insurance rules vary by state and by policy, and they change.
Read your own policy documents, and for anything with money or deadlines at stake, talk to a licensed agent, a licensed public adjuster, or your state Department of Insurance — contacting your Department of Insurance is free.
