How to Use This Glossary
Insurance policies are legal contracts, and that means they carry a vocabulary all their own. This glossary defines the terms most likely to appear across health, auto, home, and life policies. Use it as a reference when you're reviewing a quote, comparing options, or trying to understand why a claim was handled a certain way.

This Article Is General Information Only
The definitions here apply broadly across many policy types, but exact language varies by insurer, state, and policy form. Always read your actual policy documents and consult a licensed insurance agent or adviser for guidance specific to your situation.
Core Policy Terms Defined
The terms below form the foundation of nearly every insurance contract. Understanding them helps you evaluate what you're actually buying — and what you're not.
For a closer look at the declarations page specifically, our declarations page guide walks through each field line by line.
Terms That Affect What You Pay and What You Collect
Beyond the basic structure of a policy, several terms directly govern money — both what you owe and what the insurer will pay out.
- Out-of-pocket maximum: Common in health insurance, this caps the total you pay in a policy year for covered services. After you hit it, the insurer covers 100% of in-network costs for the rest of the year.
- Copay / Coinsurance: A copay is a flat fee for a covered service (for example, a fixed dollar amount per doctor visit). Coinsurance is a percentage split — you pay a share of each covered expense after meeting your deductible.
- Actual Cash Value (ACV) vs. Replacement Cost Value (RCV): ACV pays what a damaged item was worth at the time of loss, factoring in depreciation. RCV pays what it costs to replace the item new. The difference can be significant for older property.
- Umbrella coverage: An additional liability policy that kicks in after the limits on an underlying policy — such as auto or homeowners — are exhausted. It is not a standalone first-line policy.
Costs and claims go hand in hand. The Costs & Claims hub explains how premiums, deductibles, and the claims process connect in practical terms.
Exclusions and Conditions: The Fine Print That Matters
Many claim disputes trace back to two sections policyholders often skip: exclusions and conditions.
Exclusions are not loopholes — they are deliberate contract terms. Common examples include flood damage excluded from standard homeowners policies, pre-existing conditions under certain older health plans, and intentional acts excluded from liability coverage. Reading the exclusions section before a loss — not after — tells you where you have gaps worth filling with a separate policy or rider.
Conditions set the rules both sides must follow. A policyholder condition might require you to submit a proof of loss within a specific number of days, maintain the insured property, or cooperate with an adjuster's investigation. An insurer condition might govern when and how they can cancel your policy. Failing a condition does not automatically void a claim, but it can complicate one.
Understanding what an insurance policy is at its core — a contract with mutual obligations — helps frame why these sections exist.
If you identify a gap in coverage through exclusions or limits, ask a licensed agent whether a rider or a separate policy addresses it. No article can substitute for reviewing your actual policy documents with a qualified professional.
